Submit Your Presentation Abstract for Emerson Exchange Brussels 2016

Over the past several weeks we have been featuring Emerson experts who will be presenting at the October 12-16 Emerson Exchange conference in Denver, Colorado here in the USA.

If you are located in Europe, the Middle East or Africa that may be further than you want to travel to connect with the experts and share your expertise.

The good news is that an Emerson Exchange conference will take place in Brussels, Belgium on April 12-14, 2014. This conference provides an opportunity to understand what the industry is doing to compete in challenging economic times through numerous workshops, presentations, industry forums, short courses, technology exhibits and product roadmaps.

The call for presentations is now open and will be until September 30th. If you submit an abstract of your presentation and it is approved by the Board of Directors, your registration fees for the conference will be waived (for one person for each accepted presentation).

The Board offers these guidelines the types of presentations sought by the conference attendees: Continue Reading

Optimizing Multi-well Gas Lift Operations

As oil prices have remained lower for many months, many oil & gas producers have shifted their priorities from new production to optimizing existing production and reducing operating costs with the assets currently in place.

Emerson's Lou Heavner


In the quick, 2-minute video, Optimizing Oil & Gas Production, Emerson’s Lou Heavner describes how model predictive control (MPC) optimizer technology is being applied to optimize gas lift operations on producing oil wells.

Lou explains that optimized gas lift operations begin with reliable and accurate flow measurement on the injected gas being supplied to the wells. For offshore platforms and well pads with multiple wells undergoing gas lifting, it is important to optimize the allocation of the gas, particularly where supply gas is limited.

The MPC controller optimizer uses models created from the well test data to maximize production for the amount of gas injected. The platform or well pad may have constraints such as the volume of produced water, which can be handled by the water treatment process. The constraints are added to the model to reduce the injected gas to the wells with the highest water cuts to address these constraints while maximizing the oil produced. Continue Reading

Crude Oil Property Variability Requires Real-time Analysis

Emerson's Patrick Truesdale


Recently, we highlighted a recorded webinar on the use of online analyzers in refinery blending operations. The presenters, Emerson’s Patrick Truesdale and Topnir SystemsDidier Lambert, also recently wrote a Processing Shale Feedstocks article, Three steps to successful processing of shale and other opportunity feedstocks.

Three steps to successful processing of shale and other opportunity feedstocksIn the article, they highlight the challenge many refiners face who process “opportunity crudes” from shale oil and other non-conventional sources. The feedstock varies much more in terms of density, sulfur content, salt content and volumetric yield than traditional sources of crude oil have varied. They noted for traditional sources, the:

…crude assay would usually change little over time, often measured in years and only happening slowly as the well moved toward the end of its productive life. What is more, one well’s crude assay could frequently serve as a proxy for all other wells within the field.

Stable feedstocks are not the case for shale oil:

So, the type of crude assay that has been valuable in the past is no longer as useful because assays that were once good for many years, if not decades, may no longer hold from one well to another, or from one well to itself a few months hence.

Addressing the challenge of feedstocks with widely variable properties, involves three steps: Continue Reading

Increasing High-Pressure Flow Measurement Calibration Capacity

FORCE Technology high-pressure gas meter calibration facility

FORCE Technology high-pressure gas meter calibration facility

This May, the world’s largest closed loop for high-pressure calibration of gas meters opened at Force Technology in Vejen, Denmark. The facility’s purpose is to calibrate all types of gas meters that measure or settle gas types (natural gas), including:

  • Turbine meters
  • Swirl meters
  • Ultrasound meters
  • V-cone and M-cone meters
  • Vortex meters
  • Coriolis meters
  • Thermal mass flow meters
  • Mass flow controllers


Emerson’s Jacob Freeke was invited to the grand opening to present on the global development and future of natural gas measurement. He shared some trends about the growing percentage of natural gas in the total global energy supply. It is now around 23% and growing at a compound annual rate of approximately 2.5%.

Transferring the custody of natural gas between gas producers and distributors in the supply chain requires reliable and accurate measurement. As such, the demand for high-pressure natural gas calibration continues to grow. This calibration facility is part of the expanding global capacity to meet these needs. Continue Reading

Reducing Plant Energy Consumption

In an earlier post, Identifying Components then Optimizing Industrial Energy Consumption, we discussed how energy optimization initiatives were affected by what could be measured. Emerson’s Jonas Berge added a great comment to that post, which I will share here to bring it greater visibility.

Emerson's Jonas Berge


Running fans at excess speed, failed steam traps, fouling, inefficient combustion, pipe leaks, poor insulation on steam and condensate lines, relief valve leaks, tank leaks, unused equipment not turned off, valve leaks, and valves left open are some of the other reasons why plants are consuming more energy than they should. Poor combustion control, especially when fuel heat content changes, wastes energy by causing excessive stack losses. Leaking compressed air systems and valves left open, when not producing, waste the electricity that was consumed to compress the air.

Leaking steam systems waste the fuel that was consumed to generate the steam. Pumps and fans left on, when not producing, waste electricity. Water leaking and condensate not recovered waste the water itself plus the chemicals and energy required to treat it.

Most plants today only measure the energy streams in a single point at the source; where water, gas, and electricity enter the plant, from the air compressors, from the steam boiler, and from the utilities plant etc. Therefore, there is no visibility if there are leaks in an area somewhere in the plant, if consumption is higher than normal in some plant unit, or if some equipment is running when not needed.

By only looking at overall plant energy consumption, problems cannot be pinpointed so there is little or nothing that can be done to improve and sustain. Thus energy managers at most sites do not have the information they need in order to drive an energy management practices according to ISO 50001 to reduce reduction in energy consumption and losses. Whatever little data is available from the control system is infrequently put into spreadsheets manually.

Energy management is not just about electricity
