Removal of pearlescent sand in the distillation tower
Thread Content
The nitrogen pipeline at the pressure of 20,000 kPa in the lower column cracked, allowing perlite to enter and causing obstruction in the liquid-air flow path of the subcooler. How should the subcooler and the perlite in the lower column be cleaned?
Did the shutdown occur during that process? ~~If the situation is severe, it’s necessary to shut down the system, apply heat, remove the sand, and then carry out welding repairs. One can first try using forward and reverse blowing to see if the pearlescent sand can be blown away; if that doesn’t work, the pipe may need to be cut. In cases where the problem is serious, such as when a large amount of pearlescent sand has accumulated inside the tower, it’s likely necessary to cut open the tower in order to carry out repairs~~
Try not to blow air upward toward the tower, to avoid it settling in the main cooler later on, which could pose risks to subsequent operation.
