Not only is it a best-seller but production volume also exceeds expectations; the load on Ningxia Coal’s light white oil production facility has reached 130%. Author/Source: Xinning Coal. Date: February 23, 2022. Clicks: 18. In less than a year and a half since its operation, Ningxia Coal’s light white oil production capacity has achieved new milestones on multiple occasions. Currently, the light white oil upgrading and efficiency improvement unit is operating at 130% capacity, with an average daily output of 1,400 tons, generating over 21 million yuan in additional efficiency gains per month. “With full strength, it took the lead from the start, and the Ningxia Coal Oil Production Branch successfully accelerated its progress right from the beginning. Light white oil can be used in industries such as printing supplies, calibration of specialized equipment, metal processing, household chemicals, and cigarettes; it has high potential demand and a higher added value. After its official commissioning in September 2020, light white oil has become a \"star product\" for Ningxia Coal’s pursuit of refined development and operational efficiency. However, since light white oil and low-pour-point diesel share the same raw materials, in winter, -20# diesel is a key product in oil sales. Increasing its production will inevitably affect the operating load of the light white oil plant. How to control the production of diesel with different freezing points while ensuring high-load operation of the light white oil unit has become a key factor for the safe production and improved efficiency of this unit. To effectively address the issue of increasing the production of light white oil while maintaining the output of -20# diesel, the technical experts at the synthetic oil plant of the coal-to-oil division explored potential improvements by examining the operating conditions of various pumps and motors as well as their operating currents. They also conducted comparative analyses of the amount of heating steam used and the valve opening degrees to find effective ways to make adjustments” ； By collaborating multiple times with Zhongke Synthetic Oil Technology Co., Ltd. and the Research Institute of Coal Chemical Industry Technology, production plans were formulated, setting a target of 1,400 tons per day of light white oil production. Subsequently, the coal-to-oil division established a technical task force that, through stable operation, data analysis, and process optimization, continuously adjusted the temperature rise in the reactors to maintain a stable temperature of the materials within the reactors. Through continuous attempts and optimizations, it was eventually achieved that the light white oil production facility could produce 1,435 tons per day, setting a new record for output while also ensuring stability in both the amount of light white oil produced and the yield of diesel. Currently, the Coal-to-Liquids Branch of Ningxia Coal Industry is accelerating the implementation of projects with good market prospects and high return on investment, such as air separation for argon extraction and the separation of refined naphtha. Focusing on intermediate products from the Fischer-Tropsch synthesis process, the company is conducting research and making preparations regarding technologies for producing downstream fine chemicals like single-carbon cut products, white oil, and higher alcohols. These efforts aim to further extend the industrial chain and leverage its advantages.
