On the afternoon of November 13, the China Petroleum and Chemical Industry Federation organized a launch meeting for this assessment in Hangjin Banner, Ordos City, Inner Mongolia. The assessment expert panel consisted of Wang Shoujian, former chief engineer of Sinopec Group; Zhang Zhongqing, a leading expert at Fushun Research Institute of Petrochemical Technology under Sinopec; Liang Longhu, former deputy chief engineer of Luoyang Engineering Co., Ltd. under Sinopec; and Li Chen, former deputy chief engineer of the Petroleum and Chemical Industry Planning Institute. The expert group listened to a presentation by Inner Mongolia Yitai Chemical Co., Ltd. on the construction and operation of the 1.2 million tons per year fine chemicals demonstration project facility, as well as a report on the assessment plan and the preparations for it. They finalized the assessment plan and confirmed the calculation methods for various assessment indicators. Leaders and representatives from the entities responsible for completing this project, including Qi Yaping, Vice President of Inner Mongolia Yitai Group Company; Liu Shangli, Chairman of Inner Mongolia Yitai Chemical Co., Ltd.; Wang Chunsheng, General Manager; and Cao Liren, Chief Engineer at Zhongke Synthetic Oil Technology 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 image shows the launch meeting for the assessment.

The main process technologies used in Inner Mongolia Yitai Chemical Co., Ltd.’s 1.2 million tons per year fine chemicals demonstration project are the Zhongke high-temperature slurry-bed medium-temperature Fischer-Tropsch synthesis technology, which possesses independent intellectual property rights in China, as well as the Aerospace Changzheng pressurized coal gasification technology. The main construction components include six primary process units for air separation, gasification, purification, exhaust gas conversion, synthesis, and processing, along with supporting utility and auxiliary systems such as boilers, power supply, water supply, coal transportation, and storage and handling facilities. On July 7, 2017, the project underwent a successful one-time trial run, completing the entire process and producing qualified products. On September 14 of the same year, the air intake volume of the entire plant reached its designed full capacity, achieving an excellent result of reaching full operational capacity within 100 days from the start of operation. As of November 10, 2019, the project had been in operation for a total of 836 days, during which 2.2968 million tons of the main product were produced. During the inspection period, the expert team inspected on-site the main production units such as gasification units, purification units, and synthesis and processing units, as well as the auxiliary units including thermal power units, sewage treatment systems, and circulating water stations. They listened to detailed explanations provided by the technical personnel regarding the operation of these units, visited the central control room and the central laboratory, and learned about the key operational control parameters for the main production units as well as the analysis and testing procedures for raw materials and products. They also gained insight into the measuring instruments, analytical equipment, methods used, and the calculation methods for various assessment indicators, in order to ensure that the data collected during this inspection are accurate and reliable. The assessment team inspected the control center and the equipment sites. On the afternoon of November 15, the China Petroleum and Chemical Industry Federation organized a meeting to summarize the assessment results. Deputy Section Chief Wang Yunpeng from the Energy Bureau of Ordos City, Qi Yaping and Li Juncheng, vice presidents of Inner Mongolia Yitai Group Company – the entity responsible for completing this project, Liu Shangli, chairman of Inner Mongolia Yitai Chemical Co., Ltd., Wang Chunsheng, general manager of the same company, Yang Yong, executive president of Zhongke Synthetic Oil Technology Co., Ltd., and Chief Engineer Cao Liren, among other leaders and representatives, attended the meeting to mark its conclusion. The image shows the summary meeting for the assessment of Inner Mongolia Yitai Chemical Co., Ltd.’s 1.2 million tons per year fine chemicals demonstration project. Based on the inspection of the plant’s operational conditions and the analysis of the assessment data, the load of this facility reached 108.7% of the design value; the comprehensive energy consumption per unit of product was 1.98 tce per product (with purchased electricity calculated on an equivalent basis) ； Coal consumption per unit of product: 3.48 tce per product ； Water consumption per unit of product: 5.12 t/t product (winter) ； Energy conversion efficiency: 43.85 % ； Zero wastewater discharge is achieved. The evaluation expert group recommends that, building on the economic benefits already achieved by this project, efforts should be continued to innovate in the development of fine chemical products via Fischer-Tropsch synthesis, to develop new processed products, to strengthen research on application technologies and market promotion, in order to further enhance the project’s profitability.
