Selection of large compressors
Thread Content
What configuration should be chosen for a flow rate of around 1 million standard cubic feet per hour? As an additional note, the inlet gas consists of various types of feed gases, and large fluctuations in the flow rate may occur due to operational factors.

Consult the manufacturer; your parameters are incomplete.
With such high flow rates, it’s definitely impossible to use a reciprocating type. It can only be of the centrifugal or axial flow type, that is, a turbine compressor. Selecting a turbine compressor is quite complex; only the manufacturer can carry out calculations and develop proposals based on your requirements – it’s not possible for you to make the selection yourself. At most, you can estimate the approximate power and temperature levels. This post was last edited by brightpearl on 2009-4-16 18:15]
Consult the equipment manufacturer; it is necessary to provide information on the inlet pressure, flow rate, and temperature, as well as the outlet pressure and the detailed composition of the medium
Provide your usage parameters and consult major compressor manufacturers in China such as SHENGU and SHANGU.
A sudden interruption in the supply of any one of the various feed gases will cause a change in the average molecular weight of the gas, which in turn leads to changes in the compression ratio. This results in unstable operating conditions for the compressor, and even surging can occur, affecting the downstream processes.
I am an agent for compressors. As far as I know, diaphragm compressors can meet your flow requirements, but the specific selection of equipment depends on the actual operating conditions. What do you mean by multiple gas sources?

Systems with such high flow rates generally require centrifuges
Such compressors are generally centrifugal or axial-flow type. The inlet pressure can’t be 1 atmosphere, right? In short, centrifugal air compressors can now achieve an inlet volumetric flow rate of 200,000 m3/h, while axial flow compressors used as air compressors can reach an inlet volumetric flow rate of 600,000 m3/h. From a safety perspective, centrifugal compressors are recommended for raw gas compressors; the specific choice depends on the molecular weight, inlet and outlet pressures, inlet temperature, and flow rate. I hope you can inquire about prices from Shenmu Steam Turbine and Shaanxi Steam Turbine.
Based on the compressor performance curve, centrifugal compressors exhibit smaller pressure fluctuations when there are large variations in flow rate. Axial flow compressors exhibit smaller flow rate fluctuations under conditions of large pressure variations. For your optional reference.
