QuestAir to supply PSA to natural gas processing plant in California

VANCOUVER, B.C. – QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) announced today that it will supply a M-3100 pressure swing adsorption (“PSA”) system to help a Los Angeles area gas processing plant meet the California Air Resources Board CNG specification for natural gas. The customer is a large independent oil producer in the Los Angeles Basin.
 
QuestAir’s M-3100 PSA system will be used to increase production capacity at the gas processing plant, allowing the customer to produce additional gas from several wells that are currently curtailed. QuestAir’s M-3100 will separate carbon dioxide, water, ethane, propane and heavier hydrocarbons from natural gas to meet the strict quality specifications of the gas customer, Southern California Gas Company. It is expected that the project will have a payback of 8-10 months.

“This application is a logical extension of QuestAir's M-3100 PSA to meet the specific requirements of gas processors in California,” said Jonathan Wilkinson, QuestAir’s President and CEO.

“Gas utilities and the California Air Resources Board are imposing strict new quality specifications on gas producers in California to increase the methane content of the natural gas within the state. QuestAir’s M-3100 offers gas producers a compact, cost effective solution to separate hydrocarbons and other constituents present in well-head gas in order to meet these demanding specifications,” Wilkinson said.

About the QuestAir M-3100
QuestAir’s M-3100 purifies methane-containing gas streams to high purity methane, removing contaminants such as CO2 and C2+ hydrocarbons. QuestAir’s PSA process and proprietary rotary valve technology deliver higher efficiency than conventional PSA systems in a more compact, cost-effective package. QuestAir’s M-3100 system can upgrade up to 9 million cubic feet of feed gas per day.
