Since 2016, No. 711 Institute has been conducting research on technologies related to screw steam compressors. It has since collaborated with Sinopec Engineering Construction Co., Ltd., Sinopec Jiujiang Branch, and Fujian United Petrochemical Co., Ltd. to develop a new generation of screw steam compressors for aromatic compound production facilities. After more than two years of technical research and development, various technical challenges such as those related to high temperature and pressure differences were overcome, resulting in the creation of a screw-type heat pump unit with large flow rates, high discharge pressures, and high power output, featuring independent intellectual property rights. Once this device is put into operation successfully, it can reduce the energy consumption per ton of PX in aromatic compounds production by nearly 50%, which holds great practical significance for enhancing the competitive profitability of China’s aromatic compounds industry.
