초록
In this paper, two different types of natural gas liquefaction process are simulated and designed for secure a competitiveness in the industry of natural gas liquefaction plant. These processes are based on basic cascade process, and one of these is improved with two staged intercooler and the other is modified two staged intercooler. These processes are compared characteristics of performance with basic process. COP of cascade process with two staged intercooler and modified two staged intercooler showed about 13.74% and 21.64% higher than basic process, and yield efficiency of modified process improved comparing with the basic process by 25.93% lower specific power, respectively.
