ExxonMobil And QuestAir Technologies Address Increased Hydrogen Needs In The Refining Industry

ExxonMobil Research and Engineering Company (“EMRE”) and QuestAir Technologies Inc. have signed an agreement to jointly market a novel, large capacity hydrogen purifier as a compact solution for hydrogen recovery in the oil refining industry. QuestAir has been working with EMRE since 2003 to develop this advanced, rapid cycle pressure swing adsorption (“RCPSA”) system, marketed as the H-6200, for use in oil refineries and petrochemical plants. A prototype plant test is planned at an ExxonMobil refinery beginning the second half of 2006.

The multi-year agreement signed today covers the marketing of the H-6200 hydrogen RCPSA to third party customers in the oil refining industry. Under the terms of the agreement, EMRE will lead the marketing effort to refinery customers. QuestAir will support EMRE’s marketing efforts, and will be the contracting party responsible for manufacturing, supplying and commissioning of plants sold to refinery customers.

About the H-6200
The H-6200 hydrogen purifier incorporates QuestAir’s proprietary Rapid-Cycle Pressure Swing Adsorption (“RCPSA”) technology, which operates at significantly higher cycle speeds than conventional PSA systems. This results in a direct reduction in the size and cost of the equipment required to purify a given volume of product gas. The H-6200 will be marketed in the oil refining industry as a compact solution for hydrogen recovery, helping refineries address the growing demand for hydrogen to process increased supplies of heavy, sour crude oil.
