【Major Industrial Equipment in the Chemical Industry】434—SINOPEC’s technology for producing olefins through crude oil catalytic cracking has passed evaluation
Thread Content
“The technology of directly producing olefins from crude oil has always been a bottleneck restricting the transformation of China’s petrochemical industry. The promotion of the integrated technology for producing olefins through the catalytic cracking of crude oil (UPC) is also in full alignment with the objectives set out in the \"Guiding Opinions on Promoting the High-Quality Development of the petrochemical industry during the 14th Five-Year Plan period,\" issued jointly by six departments: the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Ecology and Environment, the Ministry of Emergency Management, and the National Energy Administration. These objectives include \"progressively promoting the transformation of refining projects from focusing on oil production to chemical production\" as well as \"accelerating the development and application of energy-saving and carbon-reduction technologies such as direct cracking of crude oil to produce ethylene, the use of one-step processes to generate olefins from syngas, and the use of intelligent continuous micro-reactions for the production of chemical products.\" After more than a decade of research efforts, the research team in Catalytic Reaction Engineering at the School of Chemistry and Chemical Engineering of China University of Petroleum (Huadong) overcame a series of challenges related to catalysts, reactors, and regenerator reburning. They completed pilot-scale experiments, and in August 2020, they signed agreements with Shandong Dongming Petrochemical Group Co., Ltd. and Shanghai Zhuoran Engineering Technology Co., Ltd. to jointly build an industrial test facility aimed at developing the technology for producing ethylene and propylene through catalytic cracking and expanding its use in both domestic and international markets. During the nearly two years that followed, dedicated to the promotion of this technology, the members of the research team worked together with company staff to identify and resolve issues on site in a timely manner, while also providing technical guidance and support; finally, the system was successfully put into operation in January 2022.
Recently, the \"Complete Set of Technologies for Producing Olefins via Catalytic Cracking of Crude Oil (UPC)\\", developed by a research team in catalytic reaction engineering from the School of Chemistry and Chemical Engineering at China University of Petroleum (Huadong), in collaboration with Shandong Dongming Petrochemical Group Co., Ltd. and Shanghai Zhuoran Engineering Technology Co., Ltd., passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. The appraisal experts unanimously agreed that this technology possesses independent intellectual property rights; the specialized metal oxide catalyst developed is a world first, and the overall technology is at the international leading level.
Compared with traditional processing technologies, this technique offers advantages such as lower investment, reduced resource consumption, shorter processing times, greater energy efficiency, improved safety, better environmental protection, and higher economic benefits. It can reduce energy consumption by 20% and save 30% in resource usage. The industrial application of UPC technology will fill a gap in the world, providing technical support with independent intellectual property rights for the high-quality development of China’s refining industry, particularly for the chemical transformation of private refining enterprises.
Is there any difference from the technology of the Institute of Rock Mechanics? Is the so-called ethylene ethylene dry gas? Still pure ethylene? Is catalytic cracking carried out using light crude oil?
Is the technology of the Institute of Rock Mechanics the same as that of Sinopec in Tianjin? ? ?
On April 26, 2021, the Press Office of Sinopec announced that recently, the crude oil catalytic cracking technology developed independently by the Petrochemical Research Institute under Sinopec was successfully tested on an industrial scale at Yangzhou Petrochemical, enabling the direct conversion of crude oil into chemicals such as light olefins and aromatics. This represents a major breakthrough in the industrial application of crude oil catalytic cracking technology, signaling significant progress in China’s technology for converting crude oil directly into chemicals, and positioning China as a leader in this field worldwide.
Crude oil catalytic cracking technology is one of the technical routes for directly converting crude oil into chemicals. This technology can \"skip\" traditional petroleum refining processes such as atmospheric and vacuum distillation as well as feedstock purification, converting crude oil directly into light olefins and aromatics. This approach significantly increases the production of high-value chemicals such as ethylene, propylene, and light aromatics, while simultaneously reducing overall energy consumption and carbon emissions. Sinopec stated that the test results showed that the total yield of low-carbon olefins and light aromatics increased by a factor of two, reaching over 50%; in other words, using this technology, approximately 500,000 tons of high-value chemicals can be produced per 1 million tons of crude oil processed. The successful application of this technology is of great significance in addressing the issues of overcapacity in China’s refining industry and insufficient supply of chemicals. Li Mingfeng, the dean of the institute, said that this technology opens up a new pathway for converting crude oil into chemicals, with a chemical yield of up to 70% expected. This means that for every 1 million tons of crude oil processed, approximately 700,000 tons of high-value chemicals can be produced. In the future, this technology will be applied to the construction of new chemical-based refineries or the upgrading of existing catalytic cracking units in refineries, thereby ensuring the security of China’s chemical supply chain, alleviating supply-demand imbalances in the industry, and supporting the transformation and upgrading of enterprises.
Magnificent! ! Magnificent! ! Atmosphere! ! Thank you to the original poster for sharing
It needs to be clear that this is catalytic cracking. In fact, it involves a zoned design of the reactor, rather than steam cracking. This technology can **increase the propylene yield**.
