Author: DEAR AST

In order to reduce the cold loss caused by improper piping arrangement in the cold box, the following points should be noted when piping in the cold box.
1, the pipelines can not touch each other, hot and cold pipes should be left a certain distance.
2, a variety of liquid pipeline or cold tube should be as close as possible to the internal cold container, gas pipeline arrangement in the liquid pipeline outside.
3, gas pipeline from the wall of the cold box should be a certain distance.
4、The liquid discharge pipeline should take measures to prevent the liquid from continuously vaporizing and increasing the cold loss.

In the process of operation, especially in the start-up and shutdown of the air separation unit, one-way force should be avoided on the instrument. During the start-up of the equipment, close the high pressure and low pressure valves firstly, then open the balance valve, and then slowly open the high pressure (or low pressure) valve, so that the measured medium can enter the positive (negative) pressure chamber of the transmitter. If the liquid is to be measured, the gas in the positive (negative) pressure chamber should be discharged from the upper vent. If the gas is measured, drain the liquid accumulated in the positive (negative) pressure chamber from the lower drain screw hole. After discharging the gas (liquid), close the balance valve, and then open the valve on the other side. When the equipment is shut down, the high pressure (or low pressure) valve should be closed first, then the balance valve should be opened, and then the valve should be closed on the other side.
