 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 carbon dioxide 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.
QuestAir Technology
A key step in the processing of carbon dioxide contaminated natural gas is the separation of carbon dioxide present in the gas. The QuestAir™ M-3100 and M-3200 PSA systems offer compact, low-cost, carbon dioxide separation solutions for lower capacity applications (up to 4,000 NCMH product methane). In addition,QuestAir plans to develop a larger capacity PSA system for natural gas processing based on the QuestAir™ H-6200 product The compact, skid mounted features of this product are expected to be particularly competitive in applications where space is at a premium, such as on offshore gas production platforms.
