In April 2023, Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province, undertook the 100000 tons/year DMC project of Linhuan Coking under the general contracting of China Chemical Donghua Technology. The project includes DMC gas removal tower, MN regeneration tower, DMC distillation tower, and light component feeding tank air washing tower, which are designed, manufactured, supplied, and installed by our company. The main products used include metal float valve tray, trough liquid distributor, wire mesh demister, hump support, packing support, packing pressure grid, metal and plastic material ball ring packing, metal orifice plate corrugated packing, etc.

After being installed and completed by the professional construction team of Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province in September, it achieved complete success through a one-time feeding test. The successful trial run of the DMC project also fully demonstrates the efficient execution, cohesion, and good service attitude of our downstream chain's technical level.

DMC (dimethyl carbonate) is an important raw material for the production of new materials polycarbonate and new energy lithium batteries, with broad market prospects and high added value. The project uses carbon monoxide and methanol as raw materials, and adopts the methanol gas-phase oxidative carbonylation method to produce dimethyl carbonate. After completion and production, it can produce 90000 tons/year of industrial grade dimethyl carbonate and 10000 tons/year of battery grade dimethyl carbonate, which can transform resource advantages into economic benefits.
