Abstract
In this study, computer simulation works using PRO/II with PROVISION V10.2 have been performed for a cascade refrigeration cycle using methane, ethylene and propane as refrigerants. LNG cold heat was also utilized in order to save the compression powers for the ethylene and propane refrigeration cycles. It was concluded that about 77% of compression power can be saved by using LNG cold heat through the exchanging heat with refrigerants. We could also know that the cold heat price contained in 1 ton of LNG is 16,155 won.
