QuestAir's H-3100 system will recover hydrogen from offgas produced by an ethylene cracker being installed in a new linear low density polyethylene (LLDPE) plant located near Sao Paulo, Brazil. The high-purity hydrogen product from QuestAir's H-3100 will be used in the production of polyethylene.

Jonathan Wilkinson, President and CEO of QuestAir said, "Ethylene cracker offgas is an important source of cost-effective hydrogen to meet the burgeoning demands for hydrogen in the petrochemical industry, and we are excited by the growth prospects for QuestAir's hydrogen recovery systems in this application. The advanced H-6200 hydrogen purifier that we have developed in collaboration with ExxonMobil Research and Engineering Company is targeted specifically at larger capacity applications in this market."

"In addition, this is our first sale into Latin America, which represents a significant growth market for QuestAir," Wilkinson said.
