Title: Commercialization of previously-wasted coal mine gob gas and coalbed methane

Abstract

Enrichment of a gas stream with only one contaminant is a relatively simple process (depending on the contaminant) using available technology. Most of the gas separation technology developed to date addresses this problem. However, gob gas has a unique nature, consisting of five primary constituents, only one of which has any significant value. These constituents are: methane, nitrogen, oxygen, carbon dioxide and water vapor. Each of the four contaminants may be separated from the methane using existing technologies that have varying degrees of complexity and compatibility. However, the operating and cost effectiveness of the combined system is dependent on careful integration of the clean-up processes. In summary, the system design that is expected to be the most favorable from both technical and economic viewpoints is a facility consisting of (1) a PSA nitrogen rejection unit, (2) a catalytic combustion deoxygenation process, (3) an amine or membrane carbon dioxide removal system, and (4) a conventional dehydration unit, as depicted in Figure 1.
