Muttenz, May 14, 2012 - Süd-Chemie AG, a Clariant group company, has announced that its breakthrough in CATOFIN® propane dehydrogenation (PDH) catalyst has been successful in delivering a significant increase in propylene selectivity, while simultaneously reducing energy consumption.
Since the new catalyst was introduced just over a year ago, commercial operations employing the improved catalyst have delivered a 2-3% selectivity boost as well as energy savings of between 5-10%, both of which have a significant and very positive impact on plant economics, enabling an increase in production without additional operating costs. For a new grassroots facility, this performance improvement can translate into a profit improvement of up to $30 million, when compared to using conventional catalysts.
The CATOFIN PDH process is a reliable, proven route for the production of propylene from propane; the process can also be used to produce isobutylenes from isobutane. It operates at an optimum reactor pressure and temperature to maximize conversion of propane (or isobutane) with low investment and operating costs. Süd-Chemie produces the CATOFIN catalyst, and Lummus Technology, a CB&I business sector, has exclusive worldwide licensing rights to the technology.
CATOFIN technology has been selected by 20 licensees worldwide and is in operation in 14 units today, including the largest PDH unit currently in operation with a capacity of 500 kta. A 600 kta CATOFIN PDH unit will start operation in 2013. The CATOFIN process offers superior selectivity and on-stream efficiency.
