    How do you Measure your Plant’s Energy Usage?

    Diminishing resources, rising prices and increased sensitivity to environmental issues makes the efficient use of energy more important today than ever before, especially in areas with high consumption.

    Using intelligent power management with energy-efficient components can easily optimize energy management in process plants and significantly reduce operating costs. Be sure to take advantage of systematic, scalable solutions; from basic power monitoring to complete, integrated energy management with transparent visualization of consumption from the process control system.

    Energy management is not a single product; it is a strategy. Implementing the energy management strategy can be broken down into a three-step process:

    1. Identify
    2. Evaluate
    3. Realize

    • Identify
      In order to provide transparency for energy data, intelligent devices must be capable of capturing energy information. Installing devices that have this capability creates easy tracking and measuring of energy potentials, which can be understood and incorporated into the energy management strategy. 

    • Evaluate
      Once you are able to identify the devices in the plant that are energy management capable, your process control system coupled with the plant’s energy management software (which can be incorporated as an add-on or 3rd party software package) can provide transparency of energy usage to operations and plant managers. This information can include the load profiles, trend usage and provide detailed reporting.

      Well-designed and optimized energy usage helps to reliably avoid the cost of consumption peaks. Using an energy management software package makes it possible to monitor power limits with integrated load management. The plant can selectively switch off consumers to smooth large peaks and comply with the contractual limits made with energy suppliers. Loads can be dropped in unstable supply networks, to continue operation of the other plant critical components with the remaining supply.

    • Realize
      Intelligent energy devices coupled with energy management software makes it possible to reduce energy peaks and avoid exceeding set power limits.  The operators can be made aware in real-time via Warning/Alarm messages if excess power usage is expected.  Additionally, the process control system should be able to program the load management through start/stop of electrical loads, as well as assign priorities of the loads.

    Incorporating these three steps into your energy management strategy will help you to decrease energy costs and environmental issues, and it will provide the ability to measure and understand your plant’s energy usage patterns.

    How do you level your issues with flour?

    It is pretty amazing the many types of goodies that you can create with flour. These creations require various types of flour and some of these flours, because of their composition, are tougher than others to accurately measure their levels in a silo.

    To the flour mill producer, the characteristics of each type of flour allows for the right recipe blend. In the milling process, production goes hand-in-hand with inventory. It happens that the various characteristics that flour exhibits from crop-to-crop, season-to-season or environment-to-environment can create some challenges in terms of level measurement. Thus, to accurately monitor the flour level in a silo, it requires us to take a closer look.

    So what causes variances in flour, and what should you watch for when deciding if a technology will perform as desired to meet your level measurement needs?

    Claims are often made that one technology or instrument can be suitable to all your flour level application needs; however, this is not entirely accurate. In general, non-contacting level technologies are more favorable than other technologies, but sometimes the type of flour may call for a contacting one whereas in other applications it may not be applicable.

    Remember, not all flours are created equal. The season, harvest, mesh, bleaching and maturing agents play a role in the flour’s make-up. Because flour composition varies greatly, how the flour settles or flows out of the silo can differ from one type to another. Also, the filling method, which is typically pneumatic, creates lots of dust and the aeration tends to lower the bulk density on some flours more than others. The level of humidity of the product or the environment can also be good or bad. Good because humidity increases the bulk density of the product, and bad because it increases the potential for buildup on the measuring device.

    So to minimize fussing with accurate level measurements, watch for some of the tell-tale signs that can be problematic. This will help you make better educated choices as to what types of instruments would be more in line with the process conditions that you are dealing with.

    What should you consider when picking your level device?

    Chances are that you are handling more than one type of flour, and the more that you know about the flour properties that you are dealing with, the better solution you can find for your applications.

    To help identify whether or not you need more than one type of technology, take a look at the list below to see if any of these conditions exist. 

    • Does the flour pack easily into shapes?
    • Does it exhibit a high angle of repose?
    • Does the material bridge or rat hole?
    • Does it build up on the silo walls?
    • Is the space very dusty when filling?
    • Does the inside of hatch show excessive buildup?
    • Past level experiences, does it behave differently according to the season?

    Choosing your level technology? Here are some tips that might help in the process!

    In a nutshell, dusty environments these days are easily handled with high frequency non-contact radar transmitters, i.e. 78 GHz. An easy way to remember this is:

    • If the flour tends to build up too much, contacting technologies will require more maintenance.
    • If the bulk density of the flour drops too much due to aeration, guided wave radar can be a suitable alternative. This, of course, is valid as long as the pull forces exerted by instrument cables on the roof and material contacting the instrument are not a concern. 
    • Anything operating off of laser or acoustic energy can be challenged under very dusty conditions, which makes these technologies less favorable.

    What then?

    It is wonderful that there are many kinds of flours to create the myriad of recipes we all enjoy directly and indirectly. As you know, these flours flow, disperse, compact and/or stick to surfaces differently. Trying to measure the level in a silo with one technology can be a daunting task. To help you solve your problem, understanding the flour behavior and using suitable process instrumentation can lead not only to better automation and control, but also to better recipes.

    What level measurement challenges keep you awake at night?

    Who do you turn to when you don’t have engineering or solutions support in-house?

    What is the most important factor you consider when selecting an outside solutions or engineering provider?

    Do you look for companies that are geared only to the products you have in-house, or do you look at companies that can offer guidance on an array of products? How about lead time? Are you looking for an immediate solution, or can your system set-up support a lengthy downtime depending on the solutions provider? What about the specifics of the services? Are you interested in a solutions provider that customizes their services to whatever you need, or one that has packages that you can choose from?

    Regardless of the solution you seek, all factors mentioned above will play a role in your experience with outside engineered solutions providers. You must have complete confidence that the engineering team working on your project will meet all of your process control needs.

    How can you ensure the most competent engineers in the field will be working with you?

    If your company is looking for a solutions provider, it is best to begin by considering providers that specialize in the products needed for your project. The next step involves identifying the service and support requirements for your project, and eliminating companies that aren’t up to your standards. Finally, you want to make certain that your solutions experts are actually experts – ensure that their engineers have extensive experience with similar applications and can supply the high quality products you desire.

    Investing the time and research necessary to identify a high-quality solutions provider is costly and time consuming work. So, what’s the best way to save time and money while still finding the most qualified provider?

    If your project includes process instrumentation products, I recommend reaching out to the company that you initially purchased the instrumentation from. These companies may have a department for their products or would be able to recommend a third-party that would be able to advise you.

    Recently, Siemens announced a new department that provides custom engineered solutions for process instrumentation. With a wealth of expertise along with an expansive portfolio of products and services, our handpicked engineers are able to design effective and integrated solutions for your process control challenges, without having to reach out to third-party providers!

    Siemens engineering solutions team offers experience and insight into the following industries:

    • Oil and Gas
    • Chemical
    • Food and Beverage
    • MAC (mining, aggregate and cement)
    • Water technology
    • Power Generation

    What challenges do you experience when looking for outside solutions assistance?

    How much water is used in the oil and gas market?

    Quick quiz: How much water is needed to drill and frack a horizontal well?
    a) 25,000 gallons
    b) 250,000 gallons
    c) 2,500,000 gallons

    It may seem crazy but each new well requires over 2.5 million gallons of water for completion. Not only that, besides the water needed for drilling and fracking, industry experts have found that for every one barrel of oil produced, over seven and a half barrels of water are also produced. For the production of one million cubic feet of natural gas, over 260 barrels of water are produced. With this much production, water plays a key role in keeping the well pad running and maintaining an optimized system. 

    Produced water can have a combination of materials in it; some from the fracking process chemicals (although these typically account for less than 0.5 percent of the total makeup) and others that are found in the Earth’s crust including greases, salts, etc.

    Produced water can be recycled. Some produced water is cleaned up and used in irrigation, dust control and de-icing of the roads but the majority of it is used to continue to increase well efficiency. Here, the produced water is re-injected into the well to maintain pressure and output of the well. This process must be carefully monitored to ensure optimum output and prevent shutdown of hydrocarbon stimulation.

    What do you need to monitor your process effectively?

    With this much water being produced, there is a high demand for water recycling systems and flow measurements. To ensure that your system runs smoothly, some of the key instruments that you need in your process are magnetic flow meters, level devices and valve positioners. These devices are able to perfectly into any solution needed for water transfer, frack transfer, impaired water transfer and filtration.

    Skid manufacturers have developed mobile solutions to measure water at the well site. For this application we recommend magnetic flow meters, particularly the SITRANS Mag 5100W, to monitor the flow rate of clean water where power is available. Battery-powered mag meters, like the Siemens SITRANS Mag 8000, are also beneficial and ideal for frack water impoundments/tanks that provide a solar powered flow measurement. For handling chemical compatibility for produced water and salt water flows, mag meters with a variety of liners similar to the SITRANS Mag 3100 are what you would need to use. 

    While magnetic flow meters have a huge presence in the oil and gas industry, level instrumentation is just as important. Level instrumentation, particularly the SITRANS LR250, is ideal for frack tank measurements as it provides accuracy within +/- 3mm, while the SITRANS LG250 is able to provide interface detection and dual outputs, creating an easy solution for monitoring the amount of crude separated from water. These level devices provide a greater degree of control and therefore a greater sense of reliability and efficiency to the user.

    With oil prices slowly starting to climb everyone is looking for new ways to create better efficiency and reliability on their wells. What better place to focus on then the biggest product of the US petroleum industry, water.

    How much have you focused on water in the oil and gas industry?

  • What is biogas, what are some approaches to digester optimization and how does it affect me?

    If you work in or around the wastewater industry you have most likely heard of, or been involved in some sort of investigation on solids waste digesters. Their use in the industry has surpassed just being a trend and is getting closer to becoming an ubiquitous facet of most medium-sized to large-sized facilities.

    I recently attended a 2-day conference on wastewater with my sole objective being to understand the general attitude toward the operation of digesters, what facilities are doing to optimize the production of biogas in digesters and what types of results can be expected in the quest to achieve energy independence through on site power generation. Well, starting with the basics and going into the specifics, here’s a rundown of what I’ve learned.

    What is biogas?

    Biogas is a gas that is formed by anaerobic microorganisms. These microbes feed off carbohydrates and fats, producing methane and carbon dioxides as metabolic waste products. This gas can be harnessed as a source of combustible fuel.

    Biogas is considered to be a renewable fuel and we continue to see an increased emphasis and support on the use of renewable fuels from government agencies. Since wastewater facilities have the main ingredients to create this resource, namely digestible sludge, many of our organizations are investigating and implementing energy production strategies fueled by the biogas generated in the digesters.

    What are some of the benefits of anaerobic digestion and biogas?

    Key benefits of anaerobic digestion and biogas include the:

    • Production of renewable power through combined heat and power cogeneration
    • Disposal of problematic wastes
    • Diversion of waste from landfill and an overall reduction of solid waste coming out of the plant.
    • Production of a low-carbon fertilizer
    • Avoidance of landfill gas escape and reduction in carbon emissions.

    To break down the formula, we send our solid waste to an anaerobic digester where microorganisms consume a percentage of them and then produce a methane-rich gas. That methane is then used to run a power generation unit to produce power to run our plants. Sounds simple, right?

    How do we make sure it works as planned?

    One of the first things you need to do is optimize the amount of methane that you are producing in your digester. The relative percentages of methane and carbon dioxide in the biogas are influenced by a number of factors including:

    • The ratio of carbohydrates, proteins and fats in the feedstock
    • The dilution factor in the digester (carbon dioxide can be absorbed by water)

    It has become a common practice to find local sources of high-strength waste (HSW) and add them into your digester to increase the amount of biogas produced. This is also referred to as co-digestion. There are multiple choices for co-digestion feedstock including restaurant and cafeteria food wastes, food processing wastes or byproducts; fats, oils and grease (FOG) from restaurant grease traps; energy crops; crop residues; and others.

    The addition of HSW into a digester can produce 50% - 100% increases in biogas production. The actual increase will vary depending on the current state of your digester feed stream and the types of feedstock added.

    One concern that I’ve heard many times is the local availability of these HSW, or at least the premium FOGs we are all looking for, within an easy to obtain distance from the plant. With the popularity of co-digestion increasing, it is prudent to check with your surrounding producers or haulers of FOG to make sure their waste stream isn’t already spoken for.

    Another key to success is to not give up on energy reduction and conservation just because you are now producing your own power. One of the most helpful actions in the quest for energy independence is to reduce the amount of energy you consume to run your facility. This has become a pretty common emphasis for most of us, but we can also find a source of HSW in our efforts to reduce energy usage. However, implementing and enforcing grease traps and interceptor regulations and requirements will ultimately improve efficiencies at your facility. Keeping these FOGs out of your influent stream eases the biological load coming into the headworks of the plant. Efforts can then be put into getting the FOGs that are collected delivered straight to your facility where they can be added directly to your digester. So an emphasis on grease disposal enforcement can reduce the influent load, which will reduce the power consumption of the plant, and also supply you with a nice source of premium fats, oils, and greases to load into your digester.

    Additionally, if you have producers of biological waste in the vicinity of your plant, it might be beneficial to directly pipe their HSW straight to your digester, again eliminating it from your influent stream and delivering it in a more manageable way than via the sewer. The added upfront cost should pay off down the road for both parties involved.

    Finally, utilizing the most efficient means to generate the amount of power you need with the methane produced will go a long way in determining the success of your installation. Sizing the correct power generation unit with the methane available and load needed is critical. Whether you use engines or turbines, producing power also generates heat, and capturing that heat and efficiently using it in the digester process and throughout your facility is all part of piecing together an energy independent operation.

    I’ve learned of facilities that could produce all the power they need if they could just produce enough biogas and of the facilities that are producing so much biogas that they are converting it into a type of compressed natural gas to fuel their automotive fleet at the plant. Most importantly, I’ve learned of facilities that claim to be net energy neutral today.

    As digesters and the use of their byproducts become more prominent in our industry, we are increasingly seeing them as a source for renewable energy and as a revenue stream. I believe it will be a way of life for the wastewater industry for a long time. We are still constantly learning about ways to get the most out of our digesters and their systems but we seem to be at a place now where we shouldn’t be viewing biological influent as a waste, but more as a resource.

    What do you look for when purchasing new process instrumentation?

    What is the most important factor to you when purchasing new process instruments?

    Is it the product cost, fancy features, fast delivery or warranty period? Or, is it the extensive cost of process downtime, proper regulatory reporting, or safety and reliability features of the equipment?

    Whatever your motivation is, there is no doubt that fast, accurate and reliable device configuration is critical to your process. So, what options do you have to ensure accurate configuration while managing any hurdles that may arise?

    While training sessions are extremely effective and can teach you to become an expert, is this an option for you? Do you travel frequently or are you in a position that has you running around constantly? If something does happen to your instrumentation, do you have a plan in place?

    In a world where “time is money” and keeping costs down to a minimum is the ultimate goal in every business, what options are available to you as a maintenance solution?

    If you haven’t taken training sessions in the past, you would need to call someone fast and hope to get the next available field service opening. Planning ahead would avoid costly service calls and protect you from lost downtime.

    The time is NOW to take a fresh look at upgrading technologies

    Since late-2014, the price of crude oil has consistently been dropping lower and lower. Already, we’ve already seen a decrease in drilling, fracking and production cuts, not to mention thousands of layoffs. The predictions of when prices will be back into the $70 BBL mark have ranged from July 2015 to the second quarter of 2016. While this may seem like a cruel (short-term) eternity, this could actually be a blessing in disguise for the industry.

    With dropping crude prices, it’s the ideal time to look at what technologies are used in well completion, production and pipeline transport. The industry, as a whole, needs to take a deep breath and look at how they can cut costs, increase safety and still meet environmental regulations while at the same time increasing productivity at a lower breakeven point.

    How can you significantly cut costs while still improving your system?
    With new fracking systems, although we are seeing smaller footprints when fracking a well, we’re still lacking proper management for the fracking components like water, proppant and chemicals.

    Correct management of the proper instrumentation can dramatically cut transport handling cost and demurrage fees. I have personally seen sites where the trucks have waited between 10 and 20 hours to deliver water and/or proppant. Cutting these fees alone would provide immediate payback for the proper instrumentation, in addition to a reduction in fracking costs.

    On many production sites, we are still seeing turbine meters used for flow measurement and pneumatic float to control the interface level and dump cycles of separators. These instruments can easily be upgraded to technologies that require less maintenance and offer increased accuracies over the existing systems in place. There are other benefits too like the ability to eliminate the bleed from the pneumatic devices reducing the overall emissions of greenhouse gasses.

    In addition, as output and communication systems continue to improve, companies are now able to monitor remote sites from one central location, which allows for better utilization of resources with less downtime.

    The list of where an upgrade in instrumentation is a benefit for the future of the industry is too large for a blog; however, you’re in luck! Siemens is holding their 3rd Annual Siemens Oil and Gas Innovation at the Minute Made Stadium in Houston, TX, on April 22- 23, 2015, and this will be a hot topic! We invite all who are in the Oil and Gas industry to join us, and not only network with others in the industry but to see what Siemens is doing to help decrease costs, become more efficient and safe, protect the environment and work toward shrinking the breakeven point.

    Let’s work together and have it where we can all be profitable - whether crude is at $100BBL or at $30 BBL.

    How do you create a safe environment while increasing operational efficiency?

    Over the past 50 years, there have been more than 900 instances of grain engulfment with 62% of those cases resulting in death. In 2010, over 26 fatalities, the highest number of U.S. deaths occurred due to grain engulfment. Companies need to be aware of how to reduce the chances of their employees becoming the next statistic.

    Grain engulfment can occur when an employee has to climb to the top of a storage bin to manually measure the level of product and is trapped in flowing grain. Occupational Safety and Health Administration (OSHA) has developed strict guidelines for agricultural and grain handling industries to abide by but by being proactive you can decrease the likelihood of an accident from happening. With the installation of level instrumentation, you greatly reduce trips to the top of storage bins and the opportunity for an accident to present itself.


    As companies weigh increased production against limited resources, worker efficiency continues to be a key topic of discussion. The less time workers spend making trips to the storage bins, the more time available to delegate for other important jobs at your facility. With level instrumentation, increased operational efficiency can save you time and improve your bottom line.


    What instrumentation is right for my storage bin?
