On July 12, the circulating gas compressor of Series 7 in the FTO synthesis unit of Project B’s synthetic oil plant was started up, and the system began to operate under nitrogen atmosphere; this marked the entry of this plant’s Project B into its final testing phase. By introducing nitrogen for combined operation in this system, a comprehensive inspection will be carried out on the performance and quality of the pipelines, valves, automatic control instruments, interlocks, and other utility systems within the gas-phase section of the FTO synthesis unit. At the same time, practical training will be provided to the production operators responsible for this unit, aiming to improve their ability to manage the operation of the equipment. It is understood that the circulating gas compressor, which serves as the power source for the combined cycle, is a three-in-one centrifugal compressor; this represents the first industrial application of such a type. Its successful use in coal-to-oil projects is of great significance for improving the level of manufacturing in the chemical equipment sector. At the beginning of the year, the plant took proactive measures by carefully analyzing various problems that arose during the operation of Line A for processing oil products. It addressed similar issues in Line B in advance, carrying out repairs and upgrades to equipment such as reactors, cyclone separators, circulating heat exchange separators, reciprocating compressors, along with their associated components, as well as numerous process pipelines and valves. At the same time, the original startup experience for Oil Product Line A was carefully reviewed and summarized; personnel from various positions were organized to study the revised commissioning plan repeatedly, with enhanced training efforts being undertaken. While ensuring the stable operation of Line A, skilled personnel were assigned to assist with the commissioning of Line B. The preliminary preparations such as plant purging, airtightness testing, and equipment calibration have been completed, and the commissioning activities for Oil Product Line B are progressing steadily. The project is located in the Ningdong Energy and Chemical Industry Base in Ningxia, with a total investment of around 55 billion yuan. It processes 20.46 million tons of coal per year, producing 4.05 million tons of petroleum products annually, including 2.73 million tons of diesel, 980,000 tons of naphtha, and 340,000 tons of liquefied gas ； 200,000 tons of sulfur, 75,000 tons of mixed alcohols, and 145,000 tons of sulfuric acid will be produced as by-products, with an additional 1 million tons per year of methanol being generated. On December 21, 2016, Line A of the oil products produced by the coal-to-oil project was brought online across the entire facility. By the end of April 2017, Line A for oil products was capable of producing 3,300 tons of methanol and 4,700 tons of diesel per day, with 35,000 tons of coal being consumed daily.
