Recently, an exhibition showcasing the achievements in scientific and technological innovation over the past 40 years since the launch of reform and opening up was held in Anhui Province, highlighting the progress and innovations that have taken place in this region during that time. Among them, Donghua Engineering Technology Co., Ltd. (abbreviated as “Donghua Technology”) showcased its “technological achievements in the hydrogenation of dimethyl oxalate to produce ethylene glycol”. A scale model of a plant for producing ethylene glycol via the hydrogenation of dimethyl oxalate was displayed in the Knowledge Innovation Exhibition Area. It is reported that as of December 2018, Donghua Technology had signed 22 technology transfer contracts for ethylene glycol production facilities, generating over 10 billion yuan in new contract value for the company; the transfer of process packages alone was worth more than 200 million yuan. On December 27, 2018, Donghua Technology signed another turnkey contract for an ethylene glycol production plant with Guangxi Hua Yi Energy Chemical Co., Ltd., with a contract value of 946 million yuan. The di-methyl oxalate hydrogenation to ethylene glycol plant model displayed by Donghua Technology is a 1:125 scale physical model of the main ethylene glycol production facility. This model visually presents the main process flow of the di-methyl oxalate hydrogenation to ethylene glycol technology, as well as the process by which ethylene glycol and purified terephthalic acid (PTA) are used as raw materials to produce high-quality products such as handkerchiefs or suit linings, among other polyester products, through processes like high-speed spinning.
