PL Propylene LLC, a PetroLogistics company, has announced commencement of a project to construct a 1.2 billion pound capacity propane dehydrogenation plant to produce propylene. The facility will be located in the vicinity of the Houston Ship Channel at the site of the former Houston Olefins Plant recently acquired by PL Propylene from ExxonMobil Oil Corporation (ExxonMobil). The infrastructure, logistics and certain of the processing units of the former ExxonMobil plant will be used as the platform for the project, which will utilize the CATOFIN® technology licensed by Lummus Technology. Upon completion in mid-2010, the plant will produce both chemical grade and polymer grade propylene, and will have extensive pipeline connectivity to propylene consumers. The plant will also produce commercial quantities of hydrogen and other co-products. S & B Engineers and Constructors will serve as the principal EPC contractor.
