Relationship between inlet flow rate and molecular weight of centrifugal compressors
Thread Content
There is a relationship between the inlet flow rate of a centrifugal compressor and its molecular weight; the designed molecular weight for the inlet of the syngas compressor is 11.477. However, due to system modifications, the average molecular weight of the gas entering the compressor has changed to 9.15, as a result of which the inlet flow rate cannot reach the designed value. How can this kind of problem be solved? What is the theoretical relationship between the inlet flow rate of a centrifugal compressor and molecular weight? I would appreciate guidance from those who are more experienced in this field.
Our cryogenic gas compressor has a high hydrogen content, its molecular weight is lower than the designed value, there are fluctuations in the inlet flow rate, and the fuel gas added later increases the molecular weight
By appropriately increasing the molecular weight of the gas, the inlet flow rate will increase slightly.
