Propane Cooling Applied in the Recovery of Natural Gas Liquid

The writers spend lines on their understanding about propane cooling technique in the course of development, design and manufacture together with the cooling character. Compared with other cooling process, this method is thought to be simple in flow process, convenient in operation, high in natural gas liquid recovery rate and high in applicability and elastivity. In the design of natural gas liquid recovery plants specially used for recovering C₃⁺ composition, propane cooling technique is considered to be reasonable if the C₃⁺ content is over 250 g/m³. Propane cooling technique has got its social and economic benifits and has a bright future as well according to the further analysis done by the writers.
