Sinopec Group disclosed on March 6 that the 4.6-million-ton/year catalytic cracker installed by Sinopec's deep catalytic cracking (DCC) patented technology was successfully accepted and officially put into operation on February 27. The application of DCC technology and catalysts in the world's largest olefin plant indicates that Sinopec's DCC technology has maintained a world-leading technology advantage in the field of prolific low-carbon olefins production.

Ziad S. Al-Labban, President and CEO of Rabigh Company, said at the acceptance meeting that the DCC process has played a pivotal role in the production and operation of the petrochemical complex.

It is understood that this DCC technology was developed independently by the Sinopec Research Institute of Petroleum and Petrochemicals . It is a catalytic cracking process for the production of light olefins using heavy oil as a raw material, breaking the bottleneck of traditional processes using light naphtha to produce olefins. It is internationally The pioneering use of heavy oil direct production of propylene technology can be flexibly operated according to market demand, maximizing the production of propylene, iso-olefins and high-octane gasoline.

According to the person in charge of the Sinopec Research Institute of Petroleum and Petrochemical Sciences, the scale of the plant has increased, and it is necessary to adjust the process and the catalyst. The difficulty has increased and more stringent requirements have been placed on the performance of the catalyst. At present, the largest DCC installation in China is 900,000 tons/year, and the planned construction is 2.2 million tons/year. In foreign countries, the largest installation of DCC in Thailand is 900,000 tons/year and the proposed construction is 1.5 million tons/year. India will start work for 2.2 million tons/year.

Shatrabig is a joint venture between Saudi Aramco and Sumitomo Chemical Co., Ltd. The first stage of refining capacity is 20 million tons/year, and its core unit is 460 tons/year catalytic cracker is the world's largest multi-produced low-carbon plant. Olefin plant. The device has been running smoothly since the trial run in May 2009, and all the indicators have reached or exceeded the design targets, of which propylene production reached 950,000 tons/year, and it was dubbed as "Propylene Generator" by the users.

At present, Sinopec has realized the use of independent intellectual property rights technology to design and build the world's most advanced level of 10 million-ton refinery and million-ton ethylene and related equipment, DCC, catalytic cracking, delayed coking, large ethylene cracking furnace, toluene disproportionation, SBS Wait for a batch of technology and refinery catalysts to export.
