In this article, 23 methods for emission reduction in gas transmission facilities including compression stations, transmission pipelines and valve stations have been assessed based on operability, technical feasibility and cost-effectiveness. Emission reduction potential, payback period, capital and operating costs have been considered as the main criteria, based on which all methods have been categorized in three levels. Weight factors were considered for each criterion to quantify the ultimate analysis and prioritization based on total score. Net present value (NPV), internal rate of return (IRR) and added value were also considered to precise the economic calculations. The results showed that Direct Inspection and Maintenance (DI&M) for valve stations possessed the highest priority, followed by DI&M for launcher-receivers and pipelines. The use of Absorbed Natural Gas (ANG) technique for turbine starter exhaust acquired the lowest score among other methods.
