THE WOODLANDS, Texas -- Lummus Technology, a CB&I company (NYSE:CBI), has been awarded a contract from PL Propylene LLC (a PetroLogistics company) for the license and basic engineering of the proprietary CATOFIN([R]) technology. The 1.2 billion pound (544 million metric ton per annum) capacity propane dehydrogenation plant, designed to produce both chemical grade and polymer grade propylene, will be located near the Houston Ship Channel.

The CATOFIN dehydrogenation process features the use of Sud-Chemie's latest CATOFIN catalyst in reliable fixed-bed reactors.
