Compression Report: Trade Keeps Sharp Eye on Changing Market

September 2015, Vol. 242, No. 9

It’s a topic the general public doesn’t know much about, but there would be no natural gas pipelines – hence no natural gas – without compressors. Today compression is a main topic of conversation in the industry for many reasons, environment – which includes siting, noise and emissions control – economics, and engineering/construction challenges. As the natural gas industry continues to expand and change direction, more pipelines will be built in the next few years, all dependent on compression.

Systematic Turbine Compressor Controls Employ High Performance Modules

May 2012, Vol. 239 No. 5

On its long journey from extraction to the consumer, natural gas has to be compressed repeatedly to maintain the required discharge pressure in the pipelines. Russia’s leading supplier of automation equipment for the gas turbine compressors used for this purpose places its trust in the proven “made in Germany” control technology. This ensures reliable long-term operation as well as maximum supply quality and reliability during natural gas transport.

Compressor Control Is Moving Beyond Black Boxes

February 2012, Vol. 239 No. 2

Until recently, many compressor operators considered black boxes the best available technology to maintain consistent compressor control, despite the technology’s many drawbacks. Chief among those are: 1) the lack of interoperability with other plant controls, 2) the difficulty of quickly accessing critical operating data, 3) the need for specialized tools to maintain or expand compressor control systems and 4) the demand for more redundancy and energy efficiency.

One-Dimensional Modeling For Compressor Engine Controls

September 2011, Vol. 238 No. 9

In modeling and control of power equipment, mathematical models are often used to develop robust control systems. The models are used both in the calculation of performance metrics and in determining control set-point parameters. These one-dimensional control functions require a method to determine an output value given some known input parameter. This article will describe various mathematical modeling methods that are used in compressor unit control systems as well as the advantages and disadvantages of each method.
