Natural Gas Upgrading
The United States Department of Energy estimates that natural gas production worldwide will increase from 90 trillion cubic feet per year in 2002 to 118 trillion cubic feet per year in 2015. A significant portion of natural gas produced worldwide is considered sub-quality due to contamination by carbon dioxide - in 1999 the production of carbon dioxide contaminated gas accounted for 13% of total North American gas production (Gas Technology Institute).
Natural gas pipeline operators have strict specifications with respect to the energy content of gas distributed via pipeline and carbon dioxide must typically be removed from sub-quality gas before the gas can be transported to market.
Our compact, proven, proprietary technology provides Xebec with a competitive advantage in niche markets that demand small size and significant production capacity.
For instance, Venoco, Inc, one of the largest independent oil and natural gas companies in California, purchased Xebec purification technology to purify natural gas to meet strict quality specifications in California. Xebec’s NGX PSA system will increase the quality of ‘associated gas’ produced on Venoco’s Platform Gail. The $700,000 order is the first application of Xebec’s NGX for gas processing on an offshore platform, where the system’s compact size is a significant advantage.
A key step in the processing of carbon-dioxide contaminated natural gas is the separation of carbon dioxide present in the gas. The NGX PSA systems offer compact, low-cost, carbon dioxide separation solutions for lower capacity applications (up to 4,000 NCMH product methane).
