In August 2022, the aromatic compound combined screw heat pump system developed by the 711th Research Institute of China State Shipbuilding Corporation was successfully put into operation at Fujian United Petrochemical Co., Ltd. and Sinopec Jiujiang Branch. At the project site of Fujian United Petrochemical Co., Ltd. and at the project site of Sinopec Jiujiang Branch, since 2016, the 711 Institute has been conducting research on technologies related to screw steam compressors. It has subsequently 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.
I can’t remember which aromatic compound processing unit uses a screw heat pump I’m afraid I’m too old and don’t have enough knowledge.
Is the px tower top the heat pump that provides heat to the tower bottom?
