The temperature is high after high-pressure air cooling in hydrocracking; is it feasible to replace the fan motor?
Is there any bias flow or air resistance? Equipment improvements can meet the process requirements to a certain extent, but it’s best to examine whether there are any effective adjustments that can further improve the process!
First, find out the cause; if it’s because the motor is too small, it’s not too late to replace it then.
Personal analysis is likely not very useful. 1. In air-cooling systems, finned tubes are used, so the heat exchange area cannot be increased. 2. The fan blades in air-cooling units follow specific design standards, with a fixed rotation speed per minute; increasing the motor speed poses safety risks. 3. It is necessary to check whether the temperature difference between the inlet and outlet of the air cooler meets the design requirements. 4. It is important to ensure that the water flow rate before the air cooler is stable, and to check for the formation of ammonium salts; this can be done by examining whether there are significant temperature differences across each cooler unit
