Air separation equipment customization

Air compressor intermediate cooler is generally shell-tube structure. Water is supplied inside the pipe, and gas is supplied between the pipes, which plays a cooling role through the heat exchange of fluid inside and outside the pipe. The reasons that affect the cooling effect of compressor intermediate cooler include: 1) insufficient cooling water. The heat of the air is not enough to be taken away by the cooling water, resulting in the increase of the next level of suction temperature, the decrease of gas density, and finally the reduction of exhaust volume. Therefore, the water supply pressure of cooling water should be closely monitored during operation to control the water supply. The process generally requires that the cooling water pressure should be greater than 0.15MPa (surface pressure); 2) the cooling water temperature is too high. High water temperature reduces the temperature difference between water and gas, and reduces the effect of heat and cooling. Even if the amoun...

1. The requirements of molecular sieve adsorber, electric heater and other equipment in place are the same as those of air cooling column of pre cooling system. 2. Process piping shall be constructed in strict accordance with relevant specifications and design and construction drawings. 3. The air tightness test shall be conducted before the valve is installed, and the test pressure and inspection standard shall be carried out according to the technical requirements of corresponding valves. 4. Pay attention to the direction of switch valve installation. V1201, V1202, V1207 and V1208 are front mounted valves, while V1203, V1204, V1205 and V1206 are reverse mounted valves. When the switch valve is installed, its shaft should be in a horizontal position, and the flange bolts should be evenly cross tightened. 5. The pipeline of pressure equalizing valve V1209 should have compensating bend.
