| Summary: | About 10 years ago, Korea Gas Corporation (KOGAS) carried out a feasibility study on businesses using Liquefied Natural Gas (LNG) for cold power generation, air separation, cryogenic crushing, frozen food storage, and carbonic acid. Recently, an air liquefaction plant started operations near Pyungtaek Receiving Terminal (R/T) and a cryogenic crushing plant is now partially operating near Tongyoung R/T. However, although the business of air separation has already been industrialized, the problem of increasing the amount of gas sales remains. It has been revealed that there is more increased demand in the gas-phase market than the liquid-phase market, and that there exists a different demand pattern between the air separation plant and the LNG plant. Accordingly, the final object of this study is to establish a comprehensive business plan on the use of LNG cold energy in which all situations in South Korea are taken into consideration. Here, this report deals mainly with the economical efficiency of LNG cold energy use in South Korea based on several previously published reports. First, we performed an exergy analysis on the process of LNG receiving terminals and obtained the amounts of exergy available in the present process. From the results, the cold power generation |
