What are the reasons for insufficient discharge volume from the raw gas compressor?

What are the reasons for insufficient discharge volume from the raw gas compressor? I analyze that it might be: 1) The compressor impeller or flow channels are blocked, reducing the effective flow area of the channels and thus lowering the suction volume. 2) A failure occurred in the inter-stage gas cooler of the compressor; as a result, the feed gas could not be adequately cooled after being compressed in the previous stage. This led to deterioration in the operating conditions of the subsequent compression stage, a reduction in the volume of gas entering the compressor, and ultimately a decrease in the overall gas output of the compressor. As a consequence, the output volume of gas from this compressor failed to meet the standards set for normal operating conditions. Are there any other reasons? Is it a problem with the equipment or an issue with system adjustment?
I’m not sure what raw gas you mean. In such devices of this type, the problem that usually occurs is a clogged intake filter. The problems you mentioned do exist, but they are not common. Issues such as air leakage caused by corrosion of the inter-stage gas seals or low cooling efficiency of the intermediate cooler can all be detected at any time. Not to mention the less common problems. As for issues like those related to the impeller flow channels, they’re quite absurd; if that were the case, dynamic balance would have raised objections long ago. To be honest, to learn this field, one needs to understand the principles of equipment and their mechanical structures; one should read more and ask questions. The technicians on site represent valuable resources for learning, and these should not be wasted. For reference.
Thank you. I also just graduated from university this year, so my analysis is rather superficial. By raw gas, I mean coke oven gas that has undergone desulfurization, denitration, and dehydrogenation processes – in other words, coke oven gas used to produce LNG
Oh, the more it’s a medium of this kind, the greater the requirement for cleanliness. Only in this way can the usage conditions of the equipment be met. Everything must be considered within the scope of the equipment’s design capabilities.
1. Low rotation speed； 2. Pipeline system failures, such as valve problems and pipeline blockages
