Abstract
The calorific value of general synthetic natural gas(SNG) mainly composed of methane is $9,300kcal/m^3$ or less. In order to use such synthetic natural gas as city gas in Korea, it is necessary to heat up to $10,200kcal/m^3$. Generally, propane gas is commonly used to control the calorific value of SNG. However, the price of propane gas has fluctuated widely and has been higher than the cost of producing SNG. So if the high-calorie SNG can be produced directly instead of the calorie control by propane mixing, the production price of SNG can be significantly reduced. In this paper, based on the US NETL analysis, we compare the cost of methane based SNG production and the cost of high-calorie SNG direct production.
