Thermodynamic analyses were carried out for a Linde process for liquefaction of propane and an Expander process for liquefaction of methane. Proposed process modifications increased the Linde process efficiency from 0.039 to 0.132 and the Expander process efficiency from 0.157 to 0.199. The second‐law technique employed was based on the concept of lost‐product which is defined for a fixed power input as maximum possible production rate minus actual production rate.
