New achievements have been made in the cost reduction and efficiency improvement efforts at Pu Jie Energy’s methanol production facility. Author/Source: Pu Jie Energy. Date: 2021-12-14. Clicks: 5. Since the start of the fourth quarter, the company’s methanol production unit has focused on two key areas in order to make concerted efforts to reduce costs and improve efficiency. After optimizing the roller screen of the coal mill, the slurry concentration improved once again, currently remaining at around 63%. This not only meets the requirement for a high concentration of slurry in the center facility but also increases the gas production rate. Also. The production operation indicators for the equipment’s manufacturing process and the operating parameters of the equipment were re-evaluated; some unreasonable indicators and parameters were adjusted and optimized. Continuous monitoring was carried out on the operation of the equipment after these adjustments to assess their effectiveness. By using medium-pressure nitrogen as a gas source to inflate the air bladder in the buffer tank at the outlet of the high-pressure slurry pump, the center can significantly reduce the consumption of high-pressure nitrogen cylinders ； By shifting the startup time of the backup coal grinder from the early morning peak hours to the evening, electricity costs can be saved by about 10,000 yuan per month ； By adjusting the speed of the synthetic cycle gas compressor in accordance with the level of load, 120 tons of steam can be saved per day... The methanol plant uses this kind of ‘minor’ optimization to ensure safe and efficient operation.
