Successful individual testing of the turbine in the air separation unit of Shenhua Ningmei’s coal-to-oil project Author/Source: Date: 2016-09-02 Clicks: 9 On June 27, the individual testing of the turbine in Unit 3 of Series 1 of the air separation unit in Shenhua Ningmei’s coal-to-oil project was successful. Over the past few days, through efforts such as stress analysis and optimization of spring supports, the high-pressure steam pipelines of the Shenhua Ningmei air separation units have been cleaned, completing the cleaning process for pipelines 1–3 of Series 1. After the preliminary preparations were completed, including the installation and commissioning of the turbine quick-shut valve, the insulation of the turbine, the cold-state alignment of the turbine, and the commissioning of the vacuum system, at 15:43 on June 27, Turbine No. 3 of Unit 1’s air separation plant was ready for single-unit testing. After a brief low-speed warm-up at 1736 rpm, it was raised directly to the trip speed; tests were conducted using both the MFC and Brown overspeed protection systems, and the testing was completed at 17:10. During operation, parameters such as bearing temperatures, shaft vibration, and shaft displacement were within normal ranges; all controllers were functioning properly, and subsystems including the lubrication system, air cooling system, condensate system, steam trap system, and vacuum system were all operating normally. The air separation unit for Shenhua Ningmei’s 4 million tons per year coal indirect liquefaction project is the largest cluster of air separation units in the world, with design and procurement services provided by Sinopec Ningbo Engineering Company. This cluster of air separation units is part of the upstream processing facilities in Shenhua Ningmei’s 4 million tons per year coal indirect liquefaction project; it consists of 12 air separation units, which are currently the largest in terms of production capacity in Asia, with a designed output of 100,000 standard cubic meters of oxygen per hour. This air separation unit cluster is divided into two series, eastern and western, with each series comprising 6 air separation units, along with 1 backup system and 1 nitrogen compression system. Series 1 (the 6 units) utilizes the process technology and complete equipment provided by the foreign company Linde, while Series 2 (the 6 units) employs the process technology and complete equipment supplied by the domestic company Hangyang. The 11 core air compressors are the latest models of compressor units from German company Mannesmann, with one unit having been developed through domestic efforts. Shenning Group’s 4 million tons per year coal indirect liquefaction demonstration project is the second **coal deep processing demonstration project** following the success of Shenhua Group’s direct coal liquefaction project in Ordos. It is also the largest coal-to-oil project in the world in terms of the scale of its single processing unit. The project is located in Area A of the coal chemical industry park within the Ningdong Energy and Chemical Industry Base in Ningxia, covering a total area of 815.23 hectares, of which the main factory area occupies 334.4 hectares. The project uses coal as its raw material, converting 20.36 million tons of coal per year; of this amount, 16.45 million tons are used as raw material coal and 3.91 million tons as fuel coal. It consumes 24.78 million cubic meters of water per year, and produces 4.052 million tons of synthetic oil products annually, including 2.733 million tons of blended diesel, 983,000 tons of naphtha, and 336,000 tons of liquefied petroleum gas ； By-product sulfur: 128,000 tons; mixed alcohols: 75,000 tons; sulfuric acid AN: 107,000 tons. The total investment in the project is estimated at 55 billion yuan, with completion and operation scheduled for 2016. Once operational, it is expected to generate annual sales revenue of 26.6 billion yuan and an annual total profit and tax amount of 15.3 billion yuan. Gasification employs the GSP dry coal powder pressurized gasification technology, while the oil product synthesis unit uses the UST slurry-bed Fischer-Tropsch synthesis technology developed by Zhongke Synthetic Oil.
