Shanghai Wuzheng Engineering Technology Co., Ltd. and Inner Mongolia 3D Coal Chemical Technology Co., Ltd. signed a feasibility study report contract for the coal-based ethylene glycol industrial demonstration plant project in Hohhot on April 12, 2008. The project is an extension of the coal chemical industry chain and can replace the ethylene glycol process. The production of ethylene glycol from coal is in line with China's energy structure. China's coal is rich in gas, gas is low, and oil is scarce. The production of ethylene glycol from coal has realized the comprehensive utilization of coal chemical industry, and can break the petroleum-based process route of ethylene glycol production. From the perspective of energy strategy security or economics, it will benefit the contemporary and future generations.
