A gas processing facility in the Haynesville Shale in Louisiana runs two trains processing approximately 225 MMSCFD of sour gas and was experiencing frequent filter change outs and foaming in the amine regeneration tower. This was a new plant that was put in service in four years ago and had purchased Pentair’s UltiSep® vessels for the inlet separation on trains 1 and 2 as well as upstream of their glycol unit. The plant did not utilize Pentair’s particle filtration vessels when the plant was built.
