The Yanchang Petroleum Yushen 500,000 tons/year coal-based ethanol project adopts the dimethyl ether carbonylation ethanol technology jointly developed by Yanchang Petroleum and the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, with an annual output of 500,000 tons of ethanol. The project has an investment of 6.98 billion yuan and is located in the southern area of Qingshui Industrial Park, Yushen Industrial Park, Yulin City, Shaanxi Province, covering an area of 1,365 acres. The project officially started construction on November 6, 2018, and is scheduled to reach production and standards in 2022. The construction content includes the methanol joint center (coal unloading and storage, coal gasification device, conversion device, purification device, gas separation device, methanol device, sulfur device and other devices), ethanol device (dimethyl ether, carbonylation, hydrogenation, separation, compression, heating furnace, refrigeration station and other units), as well as the new parts of public works and auxiliary facilities, and is designed to convert 1.22 million tons of coal per year.
