Air compressor system deepens potential change
(2) After compression, the air is merged into the air cooling tower of the 14000m3h air separation unit through a main pipe. Since the air has been cooled to 40, the cooling load of the air cooling tower does not increase too much, and the amount of air entering the rectification tower increases. The distillation potential is maximized. (3) After compression, the air is filtered through various levels of filters, the dew point temperature reaches -40, and the oil content is <0110-6, which meets the requirements of instrument air. To this end, the compressed air piping enters the instrument air pipe network to prevent the low pressure of the instrument air pipe network after the two sets of air separation equipments are stopped due to sudden accidents, and the system cannot safely stop and start the vehicle. (5) Pipe the compressed air outlet pipe to the 10000m3h air separation plant rectification system, which can supplement part of the air volume and increase the adjustment means. Retrofitting effect (1) Two small air compressors were installed in July 2004 and a successful test run. The compressed air was incorporated into the 5400 kW air compressor of 14000 m3/h air separation plant. After several months of running assessment, the equipment is in stable state, easy to operate, and has a high degree of automation control. The rectification potential of the 14000m3/h air separation plant rectification tower has been excavated, and the oxygen output has increased by 800m3/h compared with the previous one, which satisfies the oxygen requirement of the gasifier and solves the bottleneck problem in methanol production. With an annual operating time of 180d, methanol production increased by 4320t/a. (2) After driving successfully, it can also provide a certain amount of replenishing gas for the rectification tower when the 3200 kW air compressor fails in 14000 m3/h air separation equipment, and can cooperate with the 5400 kW air compressor to stabilize the rectification condition as soon as possible to avoid generation. Big fluctuations. The compressed air of 5600 kW air compressor was merged into the 14000 m3/h air separation plant. The liquid oxygen production increased by 90 m3, the liquid argon increased by 100 m3, and the cumulative economic benefit of the liquid was 160,000 yuan. (3) The 5600kW air compressor is integrated into the 14000m3/h air separation plant. The minimum output of oxygen is 15000m3/h, of which 3/5 of the gas is supplied to the methanol system, and the methanol is produced at 2520t, 2/5 for the ammonia system. Synthetic ammonia 1800t, with an economic benefit of 1 million yuan. Multi-layer Co-extrusion Machine
