Amoco Hugoton Jayhawk Gas Processing Plant

In June 1996 Amoco Production Company (Amoco) reached final agreement with all external stake holders to build the new Hugoton Jayhawk Gas Processing Plant in the Hugoton Field of southwest Kansas. The new plant, which began operations in February 1998, replaced both the Amoco operated Ulysses Gasoline Plant and the Warren operated Jayhawk Plant. The plant design processing capacity of 450 MMscfd will accommodate substantially all of Amoco's proprietary production and an ever increasing share of third party production as proprietary volume declines over time. The plant is well positioned to be a regional processing hub, not only for Hugoton gas, but for gas produced in Oklahoma, Colorado and the Texas Panhandle as well. Hugoton Jayhawk is designed to recover in excess of 80% of the ethane and essentially all of the propane plus components in a Y-Grade NGL product stream of approximately 31,000 b/d. Hugoton area gas contains approximately 0.4% helium, of which up to an estimated 98% is recovered in a product stream of approximately 700 MMscf/yr. The plant operates in deep nitrogen rejection to reduce the nitrogen content from an inlet level in excess of 15% to less than 3% in the residue gas. After product and inert shrinkage, the residue gas stream contains about 360 MMscfd of 1025 Btu/scf gas. ABB Randall was the prime contractor with responsibility for engineering, procurement, fabrication and construction of the plant, which is now one of the top five NGL producing plants in the U.S.
