Zhoubang Chemical has applied for a patent for a waste heat utilization system and waste heat recovery method for carbonate production units, designed to achieve energy savings in the distillation process. According to information from the Intellectual Property Office, Huizhou Zhoubang Chemical Co., Ltd. submitted an application for a patent titled “A Waste Heat Utilization System and Waste Heat Recovery Method for Carbonate Production Units”, with the publication number CN120466867A; the application was filed in June 2025. The patent abstract indicates that this invention relates to a device for producing carbonate solvents, specifically a waste heat utilization system and a waste heat recovery method for such production devices. It includes a carbonate production unit, a lithium bromide absorption heat pump unit of the second type, an expansion-compression unit, and a hot water circulation system. A heat exchanger is installed at the top of the distillation tower in the carbonate production unit; the circulating water exchanges heat with the vapor from the top of the tower within this heat exchanger before entering the lithium bromide absorption heat pump unit of the second type. After being cooled, the circulating water returns to the heat exchanger ； The second type of lithium bromide absorption heat pump units uses the heat from circulating water to generate steam waste gas, which then enters the expansion and compression unit to produce low-pressure steam ； High-pressure steam from the outside is introduced into the expansion and compression unit to generate medium-pressure steam. According to Tianyancha, Huizhou Zoubang Chemical Co., Ltd. was established in 2007 and is located in Huizhou City; it is a company that focuses on the manufacturing of chemical raw materials and chemical products. The registered capital of the company is 600 million RMB. According to the big data analysis provided by Tianyancha, Huizhou Zoubang Chemical Co., Ltd. has participated in 38 bidding projects and holds 62 patent records; in addition, the company possesses 179 administrative licenses.
