چکیده	In the current work, a framework is presented for amine solvent selection in process of gas treating. The appropriate decision making in this field affects the capital and operational costs. Multi Attribute Decision Making(MADM) techniques have been used to rank alternatives.Determination of criteria and alternatives is the most important aspect in the MADM. Criteria have been divided in two categories: physical and process.Twelve physicalindexes andnine process indexes are detected. MEA, DEA, DIPA, DGA and MDEAare intended as alternatives.Importance of criteria are expressed by weights.Weights are determined by AHPmethod. The traditional TOPSIS method has been applied for physical criteria with crisp data. The modified interval TOPSIS technique has been appliedto study the process criteria with interval data. Data of criteria and alternatives have been collected from Ilam Gas Treating Company. Solution for sour gas sweeteningis ranked by proposed approach.Based on our computations, MDEAisdefined as the best amine solvent with the average ranking 1.5.
