How to prevent water inflow accident of molecular sieve purifier in small air separation units?  
Nov 25, 2021
Author: DEAR AST

The molecular sieve of purification system has strong water absorption, but the water absorption capacity is limited to a certain extent. In order to prevent the molecular sieve from entering water during operation, the following points should be paid attention to:

The air cooling tower should be operated according to the regulations, and the gas should be introduced first, and then after the pressure rises and stabilizes;

The air volume should not be increased or decreased suddenly;

Maintain the water level of the air cooling tower, the water spray volume should not be too large, the water quality should meet the requirements, reduce the inlet temperature, and reduce the scale.

Oxygen product: liquid oxygen is pumped out from the lower tower plate of the low pressure tower and sent to the storage tank, the inner compressed oxygen pump is placed next to the liquid oxygen storage tank, the liquid oxygen extracted from the storage tank is pressurized by the oxygen pump and sent out after gasification and reheating in the main heat exchanger to get the required oxygen product in liquid air separation plant. The nitrogen product is pumped from the top of the pressure tower...

The most common failure of the liquid oxygen pump is the leakage of the seal. For the structure of mechanical seal, the key is the bad contact of the sealing surface of the dynamic and static ring of the friction pair. It is related to the grinding quality of sealing surface, the assembling quality of pump shaft and bellows, and the material of friction pair. For the labyrinth type seal structure, it is related to the adjustment of the seal clearance and the pressure of the seal gas. Other faults and solutions are as follows: 1) the pump can't start: the current is blocked. The circuit should be rechecked to switch on the current; the rotor gets stuck or the gap is too small. The pump should be removed for inspection and the clearance should be adjusted. 2) no drainage after starting: the steering of the pump is opposite. Check the motor steering, change the power wiring; the pump is not fully precooled, gas is generated. The pump should be stopped and fully precooled again; the inl...
