Hualu’s “Key Technologies for Large-Scale, High-Efficiency Low-Temperature Desulfurization and Decarbonization of Syngas” Passed Evaluation Author/Source: Gasification World Date: 2023-04-19 Views: 157 Recently, the “Key Technologies for Large-Scale, High-Efficiency Low-Temperature Desulfurization and Decarbonization of Syngas”, independently developed by Hualu Engineering Technology Co., Ltd. (referred to as “Hualu Company”), successfully passed the evaluation of scientific and technological achievements by the Shaanxi Chemical Industry Society. The appraisal committee unanimously agreed that this technology has reached an internationally advanced level. Through thermodynamic analysis and fluid dynamics simulation of the absorption and desorption processes, Hualu Company has developed thermodynamic models for gas-liquid phases under hydrogen-rich conditions, supercritical conditions, and highly polar environments. Through the operations of \"diverting flow to the lower tower/eliminating redundancy in the upper tower\", as well as the use of \"auxiliary towers\" and \"multi-point gas extraction and distribution\", the operating load per tower is effectively increased, while equipment investment and energy consumption are reduced. The newly developed multi-dimensional precision sulfur control process for ultra-high sulfur content syngas addresses the challenge of extremely high sulfur levels in syngas alongside very low sulfur levels in the exhaust gases emitted. The new technology for deep CO removal from exhaust gases developed in the syngas purification unit addresses the safety and environmental protection challenges in related fields. These technological achievements have been widely applied in the chemical industry, yielding significant economic and social benefits. They have effectively promoted technical advancements in the low-temperature desulfurization and decarbonization of large-scale syngas, and hold great importance for fostering the green and low-carbon development of this industry. This technology has been successfully applied in 15 large-scale domestic projects, including Shandong Hualu Hengsheng, Guangdong Petrochemical, Shaanxi Coal Industry, Shanxi Yangmei, Ningbo Wanhua, and Hebei Jiantao. Hualu Company is a technology-based international engineering firm that integrates services such as technology research and development, engineering design and general contracting, investment and financing, as well as specialized industrial operations. Leveraging its strengths in translating independently developed technologies into practical applications, the company is at the forefront of the industry in terms of technological innovation, engineering implementation, and digital delivery. It has undertaken over 2,900 large and medium-sized engineering contract projects as well as design projects. To date, it has developed more than 100 new processes and technologies, created over 200 new chemical products, and holds more than 300 proprietary and patented technologies.
