The 1.13 million ton/year disproportionation unit process package developed by the Shanghai Petrochemical Research Institute and with independent intellectual property rights has been reviewed by the headquarters process. The device is expected to be completed and put into operation in 2008, and its overall technical and economic indicators of the process have reached the international advanced level.
In addition to Shanghai Petrochemical, Liaoyang Petrochemical, Maoming Petrochemical and other companies will also use this technology to design large toluene disproportionation device. By then, the market share of the technology in the domestic aromatics market will reach 67%. This indicates that China has entered a mature development period in the development of large-scale toluene disproportionation device technology.
For a long time, toluene disproportionation and transalkylation technology have been mainly based on the introduction of foreign technology. Shanghai Petroleum and Chemical Research Institute, based on independent innovation and integrated multiple technologies, has developed a large-scale disproportionation device technology with independent intellectual property rights in China. The overall technical and economic indicators have reached the international advanced level, and the material consumption and energy consumption indicators are at the leading international level. They have become one of the world's three largest patent companies, and have promoted the technological advancement of China's aromatics complexes and have comprehensively promoted the overall level of technology in this field.
S-TDT toluene disproportionation technology includes a number of technological innovations and integration, with independent intellectual property rights, and it has enormous economic and social benefits.
Shanghai Petrochemical's 1.13 million tons/year disproportionation unit process package was reviewed by the headquarters process and is another result of the Shanghai Petroleum and Chemical Research Institute in the disproportionation technology field. Since the successful implementation of toluene disproportionation and transalkylation technology in Fushun Petrochemical Industry in 1997, the company has completed 400,000 tons/year of Fushun Petrochemical, 870,000 tons/year of Iran, and 1 million tons of Zhenhai Petrochemical/ The annual scale, development scale of 1.25 million tons/year of Fujian Refining & Chemical Co., Ltd., Jinling Petrochemical's 1.4 million tons/year scale, and Ukrainian Petrochemical's 1.8 million tons/year scale toluene disproportionation and transalkylation technology package have been completed and put into production. .
Take Zhenhai Refinery and Chemical Co., Ltd. as the example of the disproportionation device with a capacity of 1 million tons per year, the industrial application results show that due to the high degree of heat integration, the energy consumption is reduced by more than 38%.
