MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517055497 A) filed by Zhenhai Petrochemical Jianan Engineering Co. Ltd., Zhejiang, China, on June 9, for 'heat exchange assembly for hydrogenation of diesel and wax oil, and hydrogenation system.'
Inventor(s) include Tao, Jiang; Tang, Qiyu; Hu, Xingmiao; Wang, Jianliang; Yu, Xiaofang; LV, Bin; and Xu, Weidong.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "A heat exchange assembly for hydrogenation of diesel and wax oil, and a hydrogenation system. The heat exchange assembly comprises: a first heat exchanger, wherein an inlet of a first heat medium passage of the first heat exchanger is used for inputting a first-stage reaction effluent, an inlet of a first cold medium passage of the first heat exchanger is used for inputting a first-stage reaction influent, and an outlet of the first cold medium passage of the first heat exchanger is used for outputting the first-stage reaction influent having undergone heat exchange; a second heat exchanger, wherein an inlet of a second heat medium passage of the second heat exchanger is communicated with an outlet of the first heat medium passage, an outlet of the second heat medium passage of the second heat exchanger is used for being communicated with an inlet of a hot high-pressure separation tank, and an inlet of a second cold medium passage of the second heat exchanger is used for inputting a stripping tower bottom liquid; a third heat exchanger, wherein an inlet of a third heat medium passage of the third heat exchanger is used for inputting a second-stage reaction effluent, an inlet of a third cold medium passage of the third heat exchanger is communicated with an outlet of the second cold medium passage, and an outlet of the third cold medium passage of the third heat exchanger is used for being communicated with a downstream apparatus; and a fourth heat exchanger. Compared with the prior art, the present invention can reduce apparatus investment, and improve heat exchange efficiency."
The patent application was internationally filed on Mar. 27, 2024, under International application No.PCT/CN2024/083938.
