Large air separation unit heat exchanger head improvement

When the output pressure of turbine air compressor is constant, when the flow rate decreases to a certain value, surge will occur. Therefore, it is necessary to control the flow rate of the turbine air compressor and prevent its flow value from entering the surge zone. However, when the system resistance increases, the flow rate will surely decrease, which makes it possible for the flow value to enter the surge zone. Therefore, the common solution is to add a bypass valve from the outlet to the inlet or vent. When the turbine air compressor is normal, the valve is closed. The flow rate is reduced to a certain value, and then the flow through the turbine air compressor is increased.

The structure of the water cooling tower selected for air separation equipment has the following broad types. Sieve plate tower. Tower plate using aperture and hole spacing of the larger shower drop tower plate. Nitrogen and water are from the sieve hole through. As the water cooling tower is not working continuously and steadily, the cooling effect is not ideal, so it is no longer used. Cyclone plat...
