Economics of toluene methanol methylation for p-xylene production

Thread Content

Sea friends, has anyone worked with the units used for toluene methylation to produce p-xylene? I’m curious about the economic benefits China’s first industrial facility for toluene-methanol methylation was successfully tested in operation at Yangzi Petrochemical. The test results showed that the process technology is feasible, the engineering design meets the requirements, the facility operates stably at full capacity, and all technical parameters are superior to those specified in the design. The success of the industrial operation test marks Sinopec as the world’s first company to possess proprietary technology for toluene methanol methylation, demonstrating the advantages of Sinopec’s system and mechanisms for technological innovation. The successful development and application of this technological process have opened up new avenues for the integration and comprehensive utilization of petroleum and coal resources, while also effectively increasing the self-sufficiency rate of xylene raw materials at Yangzi Petrochemical.
