Compressed intake pressure
Thread Content
Recently, the inlet pressure of the compressors in the distillation section of my facility has been low; the water seals are in good condition, and the flow rate during conversion is high. I would like to ask experts what could be the cause?
I’ve encountered this issue; one possible reason is that the pre-compressor demister may be severely clogged. The high moisture content in the mixed gas leads to poor flow of water within the pipes, resulting in high air extraction by the compressor. Additionally, if the liquid level in the gas tank is too low or if the distance between the gas tank and its pipes is too great, this problem does not occur when the liquid level in the gas tank exceeds 55%.
The demister filter elements should be checked, and there is also the issue of water accumulation in the pipes. The demister should have a pressure difference; you can check that pressure difference.
1. Check the pre-machine demister filter element. 2. Check the moisture content in the large pipe in front of the machine. 3. Check the suction performance of each compressor to see if the filter element at the compressor inlet is dirty, clogged, or experiencing suction problems.
