Liquid in the compressor separator issue?
Thread Content
Our company has a reciprocating piston compressor. Previously, most of the condensate accumulated in the primary outlet separation tank, with almost no condensate in the secondary exhaust buffer tank. Now the situation has changed: there is hardly any condensate in the primary outlet separation tank, while the amount of condensate in the secondary outlet buffer tank keeps increasing. What could be causing this? This post was last edited by 156026692 on 2009-4-8 21:04.]
What are the inlet and outlet pressures and temperatures at stage 1 and stage 2? Is it due to insufficient purity of the gas? Or is there a small leak in the cooler?
1. The separation efficiency of the intermediate gas-liquid separator is poor; liquid is not removed in time and ends up in the second-stage cylinder. 2. The cooling effect of the intermediate cooler is inadequate, resulting in gas with a high moisture content entering the second-stage cylinder. 3. It is possible that there is a leak in the cooling jacket of the second-stage cylinder, or a leak in the coolant circulating in the stuffing box
Is the secondary exhaust pressure too high? Or the separation effect was not good earlier.
1. The first-stage outlet cooler is not effective. 2. The gas contains a high amount of moisture, and the first-stage separator does not achieve thorough separation. 3. Are there any other processes between the first stage and the second stage?
We have had leaks in the secondary water-cooled jacket gaskets here
It’s possible that the cooling effect between sections is inadequate, or internal leaks in the inter-section coolers could also lead to such a result.
There is a problem with the primary outlet cooler: 1. The circulating water line of the cooler is blocked； ⒉The pressure in the circulating water system drops, resulting in a decrease in the circulation volume.
What are the static tests performed at the beginning of compressor startup?
The inlet temperature is too high; check if there’s a problem with the primary cooling
