Successful commissioning of the core equipment for the Shanxi Xiaxin project 2024-12-10 Recently, the high-end electronic new materials project of Shanxi Xiaxin Rongke New Materials Co., Ltd. reached an important milestone: the DMC recycle gas compressor was successfully commissioned in just one attempt. This marks the entry of the project into the full-scale commissioning phase, laying a solid foundation for subsequent trial production activities. The DMC cycle gas compressor, which was successfully tested this time, is a key equipment in the DMC synthesis plant. There are 2 sets of centrifugal units in total; each unit weighs 4,400 kilograms, the power of each motor is 1,400 kilowatts, and the rated gas flow rate for each unit is as high as 46,611 cubic meters per hour. This project uses CO produced as a by-product of the new carbon-reduction materials project for coke oven gas, along with methanol supplied by the methanol production facility, as raw materials. It employs Ubiquitous Corporation’s patented CO oxidation coupling method to produce dimethyl carbonate (DMC). Through DMC synthesis and purification, electronic-grade DMC products are obtained, with DMO being produced as a by-product. Then, using DMC and purchased ethanol as raw materials, a catalytic reaction is carried out under certain temperature and pressure to produce ethyl methyl carbonate and diethyl carbonate (EMC/DEC), with methanol as a by-product. Making full use of the coke oven gas resources from the coking plant of Shanxi Axin New Energy Technology Co., Ltd. as well as the existing 300,000-ton methanol production facility, advanced and reliable process technologies are selected and the process flow is arranged reasonably to ensure safe, stable, and continuous operation of the project after it goes into production. The company has an advantage in terms of raw materials, and it uses pipeline transportation, which is safe, results in low losses, and eliminates transportation costs. Make full use of the existing utility systems and infrastructure at Shanxi Axin New Energy Technology Co., Ltd. to minimize project costs and save on investments. The total investment for the project is 1,207,552.7 thousand yuan, of which the construction cost (excluding value-added tax) amounts to 1,035,138.8 thousand yuan
