Thread Content
According to reports from July 4th, **information from the Intellectual Property Office shows that Shandong Qilu Petrochemical Engineering Co., Ltd. has obtained a patent titled “Thermal Energy Utilization System for C3-C4 Mixed Dehydrogenation Units”. The approval notice number is CN223055125U, and the application was filed in August 2024. The patent abstract indicates that this utility model discloses a thermal energy utilization system for a carbon tris-carbon tetra mixed dehydrogenation device, and relates to the field of thermal energy utilization technology. This practical new design utilizes the heat generated by the heat pump compressor as a heat source for the reboiler of the propane column and for heating the material drawn from the side stream of tower A in the C3/C4 separation tower. The heat from the aromatic solvent system is used as the heat source for the reboiler of tower A in the C3/C4 separation process, while the heat from the bottom material of tower B is used as a heat source to exchange heat with the inlet material of tower A in the C3/C4 separation tower. This approach makes full use of the excess heat generated by the dehydrogenation unit, reduces steam consumption, and thus achieves energy savings. According to Tianyancha data, Shandong Qilu Petrochemical Engineering Co., Ltd. was established in 1992 and is located in Zibo City; it is a company that operates in the field of professional technical services. The registered capital of the company is 120 million RMB. According to the big data analysis conducted by Tianyancha, Shandong Qilu Petrochemical Engineering Co., Ltd. has made investments in 4 companies in total, and has participated in 664 bidding projects. In terms of property-related information, there are 3 trademark records and 171 patent records; furthermore, the company holds 16 administrative licenses.
