Question: In industry, it is necessary to condense gases at 5–6 degrees Celsius; what substance should be used as a refrigerant? What’s the price? Operating pressure: 618 Mpa; components include the light fractions C2 to C7 from ethylene separation. Thank you!
The condensation of light hydrocarbons generally employs propane-based refrigeration systems; the refrigerant propane is not very expensive. It is currently used for both shallow and deep cryogenic processing of natural gas. The refrigeration compressors used are usually screw compressors, and there are many compressor manufacturers that produce such equipment
A cooling system using C3 propylene as a coolant can be considered. A tubular heat exchanger, with gas flowing through the tubes and liquid propylene serving as the coolant flowing through the shell. After the gas condenses, it is collected in a storage tank and then pumped back to the larger storage tank. After heat exchange, propylene turns into a gas and returns to the screw compressor system. After passing through the compressor, propylene once again becomes a liquid and goes to the heat exchanger, in such a cycle. The company I work for uses YORK screw compressors; they work very well, but the cost is relatively high.
Thank you. Do you know where I can find information on the cooling temperature ranges for propane refrigerants and the corresponding prices?
Hehe, what I’m looking for now is a refrigerant that can achieve a cooling of 5–6°C for light hydrocarbon fractions, and I want to know which one would be the most cost-effective. I need to know the price of such refrigerants in order to calculate the associated costs for cooling utilities~
