Abstract
BOG(Boil Off Gas) is formed about 0.05 vol%/day from LNG(Liquefied Natural Gas) tanks of LNG receiving terminal. To recycle the BOG using direct contacting, Previously the quantities of LNG and BOG is mixed at the ratio of 11:1 by mass. However simple this process uses, there is the difficulty of processing operation resulted from decrease of using LNG in summer. To complement these shortcomings, Advantages of the process are investigated by comparison of cost and analysis of the indirect contact method using LNG cold energy. It was studied that principles and types of development using LNG cold energy which is abandoned in the carburettor and found how to contact each to find the appropriate cold energy development process. Therefore, in this research, the indirect contact method will be investigated the feasibility of a comparative analysis by using HYSYS.
