The issue with the compression ratio
Thread Content
Our syngas compressor is designed with a rated speed of 11,830; due to the inability to achieve the desired compression ratio, the speed was increased to 11,950. The compression ratio keeps changing, ranging from 2.5 to 2.7, and occasionally reaching 2.8. Let’s discuss what factors can affect the compression ratio How to improve?

Stabilize the downstream system and then carefully analyze the reasons, such as whether there is backpressure in various sections of the compressor and the opening degree of the anti-surge valve. If that doesn’t work, then the issue of equipment scaling should be considered, as well as factors like the inlet filter.
Reply to 2# Believe in transcendence: What temperature does it refer to?
Reply 4# pengba: It definitely refers to the outlet temperature.
The temperature at each level must have an impact, right!
The inlet temperature, medium composition, and other factors have an impact
The inlet gas temperature, pressure, and gas composition all affect the compression ratio.
Logically, a higher molecular weight should result in a greater compression ratio. However, the actual molecular weight is higher than the designed value, yet the desired compression ratio is still not achieved – could there be a problem with the compressor itself? Not enough suction? When the load reaches 80~90%.
It is related to the inlet temperature; if the inlet temperature is high, the gas expands more, and to compress it to the desired outlet pressure, the rotational speed must be increased
