The main goal of this research work is to provide an economic evaluation about the controlling of natural gas liquid dropout. The devloped idea is to minimize the natural gas losses in pipeline integrity management companies for the sake of controlling Un-accounted for gas (UAFG). The main idea is to possibly recover those valuable liquids to convert them in a liquid fuel. The econoimc analysis of the overall problem has been discussed.  The overall associated cost with the adsorber unit is calculated. Finally the Net present value, Pay back period, Accounting rate of return and Internal rate of return has been calculated.   

Key words: Economic Analysis, Hydrocarbon Natural Gas Liquids (HNGL’s), Natural Gas Pipelines
