【Ten Years of Great Progress in Chemical Engineering Technology】The Complete Process Technology for the Catalyze-Free Partial Oxidation of Coke Oven Gas to Synthesis Gas from 2015 to 2020

Thread Content

Ningxia Baofeng Energy Group Co., Ltd. has collaborated with East China University of Science and Technology to build the largest single-series facility of its kind in Lingwu City, Ningxia – an installation capable of producing 75,000 Nm3/h of syngas through the non-catalytic partial oxidation of coke oven gas, using the technology developed by East China University of Science and Technology. Construction of this facility began in August 2011, and it was put into operation in May 2014. By 2019, it had been in operation for nearly 5 years. The facility has operated safely, stably, over long periods of time, at full capacity, and with high quality; its product quality meets the design specifications, and it meets the requirements for performance evaluation. From March 26 to 29, 2019, the China Petroleum and Chemical Industry Federation organized an on-site evaluation team to visit Ningxia Baofeng Energy Group Co., Ltd., where a 72-hour continuous operation test was conducted on the facility for producing syngas through the non-catalytic partial oxidation of coke oven gas. The assessment expert panel consisted of three experts: Sun Zhengtai, an expert from the Coal Chemicals Committee of the China Petroleum and Chemical Industry Federation; Hu Wensheng, the deputy chief engineer of Donghua Engineering Technology Co., Ltd.; and Zhao Fangping, the deputy general manager of the National Reserve Company at China National Petroleum Corporation Lanzhou Petrochemical Company. On March 29, 2019, the China Petroleum and Chemical Industry Federation organized a review meeting. Based on inspections of the on-site operation conditions and analysis of the data obtained from evaluations, it was determined that the non-catalytic partial oxidation unit for coke oven gas was operating in a stable, efficient, and optimal manner; both the performance of the unit and its technical parameters met or exceeded the design values. The CH4 content in the synthetic gas produced by this unit was 0.22%, while the hydrocarbon conversion rate was 98.8%. High-temperature non-catalytic partial oxidation can decompose highly toxic pollutants in coke oven gas, such as organic sulfur compounds like thioethers, phenols, benzene, naphthalene, etc., at high temperatures within the conversion furnace ； No pre-conversion desulfurization is required; it is not restricted by catalysts related to sulfides, temperature, or carbon deposition, and no hazardous waste is generated ； It features low COD and suspended solids levels in wastewater, low discharge amounts, and recycling; moreover, the syngas contains no carbon black, giving it excellent environmental properties. On January 10, 2020, the China Petroleum and Chemical Industry Federation organized experts in Beijing to hold an appraisal meeting for the scientific and technological achievement of the \"Complete set of technologies and equipment for the catalyze-free partial oxidation of gaseous hydrocarbons to produce syngas\", which was developed through collaboration among institutions such as East China University of Science and Technology, Ningxia University, Sinopec Ningbo Research Institute, Ningxia Baofeng Energy Group Co., Ltd., China Tianchen Engineering Co., Ltd., and Xi’an Tuowonengdong Technology Co., Ltd. The appraisal committee is composed of 13 renowned experts in the field of energy and chemical engineering, including Academician Xie Kechang from the Chinese Academy of Engineering, Academician Jin Yong from Tsinghua University, Academician Jiang Jianchun from the Institute of Forest Products Chemistry, Chinese Academy of Forestry, Academician Sun Lili from Sinopec Engineering Co., Ltd., and Academician Ren Qilong from Zhejiang University. The meeting was chaired by Wang Xiujiang, deputy director of the Science and Technology Department of the China Petroleum and Chemical Industry Federation. The appraisal committee believes that the technical raw materials in question have strong adaptability, significant innovation, and independent intellectual property rights, placing them at the international leading level.
