The Gasification Center of Inner Mongolia Yitai Coal-to-Oil Company actively implements the company’s strategies for reducing costs and increasing efficiency, takes proactive actions, and strives to find new ways to save energy and reduce consumption. Among them, the coal slurry concentration project, which was given priority for implementation, achieved successful commissioning on the first attempt and yielded results in terms of energy savings and consumption reduction. ? On November 3, 2017, the gasification unit at the Gasification Center organized pre-commissioning inspections and tests, as well as individual tests of the pumps, for the coal slurry concentration unit. The instrumentation staff was contacted to conduct a thorough check of all instruments, valves, and PLC control systems in the system. The electrical staff was engaged to inspect and lubricate the motors of the mechanical equipment; any issues identified were promptly reported to the maintenance center for resolution, thereby ensuring that all preliminary preparations were in place for the smooth operation of the system. On November 21, 2017, the Gasification Center conducted a water-cooled commissioning test on the coal slurry concentration unit. In January 2018, the Gasification Center, in collaboration with the Production Assurance Department, calculated the amount of synthetic oil wastewater generated; the conclusion was that the level of synthetic oil wastewater could be maintained stable once the slurry concentration unit was put into operation. On January 8, 2018, the manager of the gasification center organized the managers of the gasification unit, the equipment manager, process and equipment technicians, process supervisors, and safety officers to carry out the preparatory work prior to starting up the coal slurry concentration unit, after which the startup phase began. Thanks to the strict implementation of the relevant regulations set by the center during the previous phase of inspections, tests, individual unit trials, and water integration tests, the slurry concentration unit was able to start operating successfully on the first attempt. After the coal slurry concentration unit was put into operation, thorough calculations showed that the concentration of the coal slurry in tank V1106 increased from 56.7% before operation to 59.3%, the gas generation per ton of slurry rose from 1120 Nm3/ton to 1160 Nm3/ton, the effective gas yield improved from 78% to 80%, the total gasification load decreased from 117 m3/h to 113 m3/h, the coal consumption dropped from 600 to 580, and the oxygen consumption fell from 440 to 430. Since the commissioning of the coal slurry concentration unit, the gasification center and gasification facilities have actively optimized various parameters, thereby expanding the range of raw coal that can be used and enhancing the unit’s adaptability. This has laid an important and solid foundation for the long-term operation of the gasifiers. On this basis, the gasification center will continue to optimize the processes to ensure the safe and stable operation of the system, and achieve further improvements in energy conservation and consumption reduction.
