Yankuang’s 100,000-ton/year high-temperature Fischer-Tropsch synthesis industrial demonstration plant passed the evaluation / Author/Source: Chemical Industry Network – Coal Chemicals / Date: 2019-09-12 / Clicks: 20. From September 7 to 10, the China Petroleum and Chemical Industry Federation organized an expert team to conduct a 72-hour continuous operation assessment of Yankuang’s Yulin 100,000-ton/year high-temperature Fischer-Tropsch synthesis industrial demonstration plant at Shaanxi Future Energy Chemical Co., Ltd. On September 7, the China Petroleum and Chemical Industry Federation organized a meeting to launch the assessment process. The assessment panel consisted of Professor Ma Xiaoxun from Northwest University, Professor-level senior engineer Liang Longhu from Sinopec Luoyang Engineering Co., Ltd., and Professor-level senior engineer Li Chen from the Petroleum and Chemical Industry Planning Institute. The panel listened to a presentation by Shaanxi Future Energy Chemical Co., Ltd. on the construction and operation of the 100,000 tons per year high-temperature Fischer-Tropsch synthesis industrial demonstration plant in Yulin, as well as a report from Shanghai Yankuang Energy Technology R&D Co., Ltd. on the assessment plan and the preparations for it. The assessment plan was finalized, and the calculation methods for various assessment indicators were confirmed. Leaders and representatives such as Sun Qiwen, Deputy General Manager of Yankuang Group Co., Ltd., and Zhu Qingrui, General Manager of Shaanxi Future Energy Chemical Co., Ltd., attended the launch meeting. The meeting was chaired by Wang Xiujiang, deputy secretary-general of the Coal Chemicals Committee of the Petrochemical Federation. The 100,000 tons per year high-temperature Fischer-Tropsch synthesis industrial demonstration plant in Yulin, operated by Yankuang, utilizes the high-temperature Fischer-Tropsch synthesis technology independently developed by Shanghai Yankuang Energy Technology R&D Co., Ltd. The project was EPC-general contracted by Hualu Engineering Technology Co., Ltd.; construction began in June 2017. Since it started operating on an industrial demonstration basis on April 20, 2019, it has been in continuous operation for over four months. During the assessment period, the expert group conducted on-site inspections of the main production systems such as catalyst activation, high-temperature Fischer-Tropsch synthesis, and reaction water distillation, as well as the auxiliary production systems for utilities, safety, and environmental protection, to examine their operational status in practice ； Checked the original data records ； Inspections were conducted of the control room, analysis room, and on-site sampling areas to ensure that the data collected for this assessment are accurate and reliable. On the morning of September 11, the China Petroleum and Chemical Industry Federation organized a meeting to summarize the assessment. Based on the inspection of on-site operation conditions and the analysis of performance data: the device operated continuously at full load for 143 days, with the load reaching 102% of the design value. The products produced were high-temperature condensates (heavy oil), low-temperature condensates (light oil), C2+ gaseous low-carbon hydrocarbons, mixed alcohols, and CH4. The selectivity for methane was 10.03%, for C5+ hydrocarbons it was 52.54%, for oxygenated compounds it was 10.48%, and for total olefins it was 52.38%; among these, the selectivity for ethylene was 3.75%, for propylene it was 8.42%, and for C4+ α-olefins it was 29.07%. The evaluation expert group believes that the overall process flow of this device is advanced and reasonable; the process operating conditions are well in line with the design values. The carbon number distribution of the high-temperature Fischer-Tropsch products is narrow, with a predominance of short-chain olefins, and no wax components are present. The olefin content is high, especially that of high-value-added α-olefins. This allows for the production of high-value-added chemical products that cannot be obtained or are difficult to obtain through conventional petrochemical routes. It enables the development of a processing approach that focuses on high-end, fine chemical products, supplemented by high-end oils, thereby enhancing the competitiveness and market viability of the products. Such an approach provides reliable technical support for the design, construction, and operation of large-scale industrial facilities for the indirect liquefaction of coal using high-temperature Fischer-Tropsch synthesis. High-temperature Fischer-Tropsch synthesis technology can be effectively integrated with existing technologies such as direct coal liquefaction, low-temperature Fischer-Tropsch synthesis, coking, and petroleum refining. By leveraging the advantages of each approach and minimizing their disadvantages, it is possible to maximize the value of the products produced and extend the industrial chain, thereby providing important technical support for the clean utilization of coal and its efficient circular development in the future.
