Sinopec’s DCC-PLUS technology with self-owned intellectual property right was successfully applied in a 1.5 million tonnes/year device of Thailand's IRPC Company recently.
The DCC-PLUS technology is an improved deep catalytic cracking technology for propylene production, which is developed by Sinopec Research Institute of Petroleum Processing (RIPP). The technology has advantages of increasing the yield of propylene, butylene and gasoline and reducing the yield of byproducts such as dry gas and coke.
