Midstream Company Case Study
Midstream services are an integral part of transporting natural gas, crude oil, condensate, and NGL commodities across the United States. With an expansive gathering, processing, fractionation, transportation, and logistics assets located in the U.S. pipelines are strategically focused on core growth areas of the Permian’s Midland and Delaware basins, Oklahoma’s Midcontinent, and Louisiana’s Gulf Coast. This particular customer operates approximately 11,000 miles of gathering and transportation pipelines, 20 processing plants with 4.8 billion cubic feet of net processing capacity, and seven fractionators with 260,000 barrels per day of net fractionation capacity.
The Compressor Station faced high levels of iron sulfide and other oxides that were contaminating systems downstream.
This Compression Station is one of 25 compressor stations throughout the U.S. with more added each year. Iron sulfide is the most prominent contaminant in natural-gas pipelines and compression equipment in pipeline, refinery, gathering, and storage applications. Black powder collects in gas pipelines, causes wear and reduced efficiency in compressors, clogs instrumentation and valves, and leads to flow losses. Iron sulfide has both a chemical and a microbial source in pipelines. The most common way of dealing with black powder is to filter it immediately before it enters a compressor station or processing plant. Filters are usually specified and supplied as a part of the compressor design package when the unit or piping is installed. Because iron sulfide shears so easily, it frequently breaks down into submicron-sized particles, which require even-finer mesh filters. There are two vessels at this location, a low pressure system holding 29 elements and a high pressure system holding 18 elements. Because of the amount of iron sulfide build-up the competitor elements were allowing liquids to be passed downstream.
Jonell installed Twist-LOK filter elements to address the iron sulfide contaminants and eliminate liquids downstream.
The Twist-LOKTM elements have three sealing points which eliminated the liquids flowing through the bypass and by optimizing the media options reduced the contaminants downstream.
By installing Twist-LOK filters, the Compressor Station reduced the impact of the iron sulfide contamination.
The success with the Twist-LOK elements carried over to other midstream gas plants in the same company. Improvements were realized intermediately which helped to preserve equipment downstream. The improvements resulted in millions of dollars in savings.
