Knowledge of twin-screw compressors
Thread Content
During the design process, it is known that a certain volume of gas is involved, with the inlet pressure and temperature being at normal atmospheric conditions. With a compressor, I want to know how to calculate how many compression stages to choose How many compressors should be selected? Pressure ratio? Exhaust temperature? Exhaust pressure? Electric energy consumed? How much cooling circulating water is needed? How are these calculated? Are there any book recommendations or formulas on this topic? I’m a complete beginner and feeling very panicked; I’m waiting online, hoping experts can help: handshake
This falls under the category of equipment selection; generally, manufacturers choose from the models available in their own factories, making decisions based on the composition of the medium, pressure, and temperature specified by the user. There is no standard textbook on this topic
First, you need to determine which type of compressor is suitable for the given operating conditions based on the components, flow rate, and inlet/outlet pressures. Only after that can you decide on the number of stages. Once the compressor type has been determined, it’s possible to calculate the shaft power and the outlet temperature
