About Gas Separation Technology LLC

GST was formed in 1991 to develop gas enrichment processes for small, low quality methane sources. The goal is to achieve a positive environmental impact by reducing methane emissions to the atmosphere, while at the same time utilizing energy resources that are generally being wasted.

Early on, GST obtained a Small Business Innovative Research grant from the U.S. Department of Energy for removing contaminants from coal mine methane gas mixtures, but most of the effort, amounting to over half a million dollars worth, has been self financed to date. The owners of the company are Major W. Seery; Raven Ridge Resources, Incorporated; and U.S. Zeolites, Inc.

Seery has a Geol. Eng. degree from the Colorado School of Mines and attended Stanford University's Graduate School of Business. He had over thirty years varied experience in the mineral industry, including exploration, production, accounting and taxes, and general management before founding Gas Separation Technology.

Raven Ridge Resources, based in Grand Junction, Colorado, is a service organization specializing in coalbed methane assessment, evaluation and research. Its clients include a number of major coal and oil and gas companies, as well as the U.S. Environmental Protection Agency, the World Bank, AID, and the United Nations. It has been active in the United States, Spain, Eastern Europe, both Russia and countries of the former Soviet Union, China, Australia and New Zealand. Raymond C. Pilcher, a graduate of the University of Texas, is President.

U.S. Zeolites, based in Arvada, Colorado, mines and processes zeolite from a large deposit located in Sweetwater County, Wyoming. U.S. Zeolites is a subsidiary of Addwest Minerals, Inc., a small, publicly held gold mining company. An associated company is Water Remediation Technology, which uses natural zeolite for various water cleanup applications.
