Maoming Petrochemical: Full cooperation in the high-load calibration tests for coal-based hydrogen production units. Author/Source: Sinopec News Network. Date: 2019-08-16. Clicks: 31. “We must provide full cooperation in the high-load calibration tests of the coal-based hydrogen production units used in oil refining; it is essential to ensure a stable power supply and the proper operation of key equipment.” ”On August 14, during the morning meeting of Maoming Petrochemical’s Thermal Power Division, the division’s management and the leaders of the relevant departments emphasized the need to ensure a stable supply of electricity and steam during the load ramp-up tests of the coal-to-hydrogen facility. The purpose of the high-load calibration test for coal-to-hydrogen plants is to determine the maximum load and maximum production capacity that the plant can achieve under stable operation, to identify the bottlenecks restricting an increase in the plant’s load, and to provide a scientific basis for optimizing production processes and reducing energy consumption. During the high-load calibration tests of the coal-to-hydrogen plant, the Thermal Power Division worked diligently to ensure stable supply and operation. Electrical Workshop 1 has established a special care team to fully assist in ensuring the stable supply of power to the electrical system. The special care team has assigned dedicated personnel to enhance the maintenance of the substation, and to conduct more thorough inspections of all equipment within it. In particular, they monitor the operating parameters of key devices such as incoming lines, PTs, transformers, and frequency converters, to check for any signs of overload or overheating. Enhance on-site monitoring of critical equipment such as slurry pumps and circulating hydrogen compressors, with a focus on checking parameters such as motor vibration, temperature, and current. The frequency of daily inspections has been increased from 2 times to 4 times in order to keep track of the operating conditions of these key devices in a timely manner. Workshop 1 focuses on strengthening the monitoring of CFB boiler systems; operators pay close attention to the condition of these boilers. The main operator and the assistant operator maintain close communication, keep an eye on the boiler’s combustion process, and are ready to use gas guns at any time to ensure stable operation of the steam network and maintain steam balance, thereby meeting the varying steam demands of the coal-to-hydrogen production facility. On the morning of the 14th, there were changes in the hydrogen content in the dry gas. The operators in the power workshop worked closely together, following the instructions from the production control team, and carried out their tasks carefully, thus successfully adjusting the boiler load. This not only met the requirements for testing the coal-to-hydrogen facility but also ensured that the stable operation of the boiler system was not affected. On the afternoon of the 14th, the coal-to-hydrogen plant successfully completed its high-load calibration test. The plant’s load was gradually reduced, and the Thermal Power Department continued to monitor and adjust the balance of gases. Operators in the Power Workshop kept a close eye on the effects of changes in gas composition on combustion, making timely adjustments to ensure the stable operation of the boiler system.
