Heilongjiang Anruijia Petrochemical in China has selected the petrochemical manufacturing technology developed by Honeywell-owned UOP for production of key constituents for plastics, synthetic rubber and fuels.
The C4 Oleflex technique from UOP has been selected for the production of isobutylene, a vital constituent for synthetic rubber and fuels. Heilongjiang Anruijia Petrochemical will also employ the UOP Butamer technology to manufacture standard butane which is the raw material for ethylene, the main constituent of plastics.
Heilongjiang Anruijia Petrochemical expects the new units to commence operation in 2014 with a targeted annual capacity of 180,000 mt for isobutylene and 150,000 mt for butane. The isobutylene facility will be the first production plant in China to be solely based on the UOP C4 Oleflex technology. It is also the first to secure the license for the UOP Butamer process in China. UOP will also support Heilongjiang Anruijia Petrochemical with technology licensing, technical services, engineering design, equipment, staff training and catalysts required for the plant development.
The C4 Oleflex process facilitates low cost production of isobutylene from isobutene by catalytic dehydrogenation. The technology features the smallest environmental impact by adopting a completely recyclable catalyst system derived from platinum-alumina and through low water and energy consumption. In addition, uninterrupted supply of catalysts is facilitated for steady-state operations by independent regeneration and reaction systems that ultimately results in high levels of reliability, on-stream factor and flexibility of operation. Till date, UOP has commissioned two Butamer units for standard butane production and 75 units for isobutene production. UOP has installed six C4 Oleflex units and prior to that, nine C3 units for propylene production.
