Technical Exchange Meeting on Advanced Purification of Coke Oven Gas Held Author/Source: Sinochem New Network Date: 12-15-2020 Clicks: 16 On December 12, the Supergravity Chemical Engineering Innovation Team from North University of China, Saiding Engineering Co., Ltd., and Shanxi Juyuan Coal Chemical Co., Ltd. jointly held a meeting to summarize the results of field experiments on the advanced purification of coke oven gas and to exchange technical insights, with a focus on the pilot-scale implementation of this technology. Professor Yuan Zhiguo from the Supergravity Chemical Engineering Innovation Team at North University of China explained that the experimental research on the deep purification of coke oven gas using supergravity was carried out on the side stream of coke oven gas at Juyuan Company. Supergravity collectors were used as the purification equipment, and the following experiments were conducted: first, methanol or water was used as a detergent to study and test the efficiency of supergravity collectors in removing dust, tar, and naphthalene from coke oven gas ； Second, methanol or water is sprayed into the gas pipeline to study and test the degree of contamination of coke oven gas on the filler of the hypergravity catcher, as well as the removal efficiency of dust, tar, naphthalene, and other substances in the gas. Based on the test data collected over 40 days, this technology has achieved the desired results in removing naphthalene, ammonia, tar, and dust. Coke oven gas contains substances such as naphthalene, tar, dust, and sulfides. Even after processes such as cooling, dust removal, desulfurization, decyanation, denitration, and naphthalene removal, it still causes blockages in pipes and compressor valves, forcing the compressors to be shut down for maintenance almost weekly, which severely impacts production and represents a significant challenge for the industry. This field experiment represents an attempt at innovative collaboration between the Supergravity Chemical Engineering Innovation Team at North University of China, Saiding Engineering Co., Ltd., and Shanxi Juyuan Coal Chemical Co., Ltd. All three parties expressed satisfaction with the progress of this technology, noting its advantages such as high purification efficiency, small space requirements, low investment costs, and low operating expenses. They decided to further improve this technology and launch large-scale industrial demonstration projects as soon as possible.
