On September 6, 2019, Hebei Jingzhi Technology Co., Ltd. added two more invention patents authorized by the State Intellectual Property Office, namely “A desulfurization solvent and treatment process for sulfur tail gas treatment” (ZL.201610350149.1) and “A sulfur tail gas purification process that can be directly discharged after treatment” (ZL.201710290388.7). To date, the company has more than 40 patents, including 33 invention patents. The Claus process is one of the methods for recovering sulfur from acid gases and remains the main process for acid gas treatment to date.
2019On September 6th, Hebei Jingzhi Technology Co., Ltd. was granted two more invention patents by the State Intellectual Property Office, namely "A desulfurization solvent and treatment process for sulfur tail gas treatment" (ZL.2016 1 0350149.1)and "A sulfur tail gas purification process that can be directly discharged after treatment" (ZL.2017 1 0290388.7). To date, the company has more than 25 patents, including 19 invention patents.
The Claus process is one of the methods for recovering sulfur from acid gases, and it remains the main process for acid gas treatment to this day. After the 1960s, due to the gradual strengthening of emission limits on SO2 in sulfur tail gas by developed countries, requiring a total sulfur recovery rate of up to 99.8%, sulfur tail gas treatment technology was developed.2 Under the increasingly severe environmental situation in China, and in order to meet the increasingly stringent environmental standards of the country, our company has further upgraded the sulfur tail gas treatment process (SCOT) through research and development, resulting in these two new invention patents:
According to the needs of the process, single-tower dual-function solvent, double-tower dual-function solvent, and pressurized desulfurization processes can be used to effectively remove HS and COS, achieving clean production (no slag discharge) and clean tail gas indicators (SO2 emission <50mg/m2H2S and COS are effectively removed, realizing clean production (no slag discharge) and clean tail gas indicators (SO2emission <50mg/m3) , ultimately achieving the direct tail gas discharge goal described in the patent.

On November 16, 2022, the Euro IV gasoline upgrading project at the Hengyuan Refinery in Malaysia was successfully started up, producing qualified products. This project uses our company's gasoline extraction and hydro-desulfurization combined desulfurization technology (referred to as "EHDS"), which won the second prize of the National Technological Invention Award. Our company provides a complete process package for pre-hydrogenation, extraction desulfurization, and heavy gasoline hydrogenation, with Global Company as the general contractor. At the request of the owner and Global general contractor, an experienced team of technical experts was sent to the site in July 2022. In the face of the risk of the epidemic, they actively participated in the cooperation of various stages of the device "three checks and four determinations", sealing test, water linkage transportation, and commissioning, and carefully carried out the work.
