Techno-economic feasibility of flare gas utilization using adsorbed natural gas

Adsorbed natural gas (ANG) is a natural gas storage technology, which is potential to transport natural gas in small and medium quantity. The objective of this study is to determine the techno-economic feasibility of ANG technology for flare gas to consumers around flare gas sources. The method is process simulation, economic calculation and optimization with variables being ANG selling price, flare gas price, and the percentage of capital financing by the government. The process simulation shows that the ANG product is in the range of 2.07 MMSCFD - 2.97 MMSCFD. The economic calculation results in the interest rate of return of less than 10%. With optimization, the IRR increases to more than 20%.
