TECHNOLOGY SELECTION FOR IRAN'S GAS FLARE RECOVERY SYSTEM

About 70% of gas flaring in the whole world produces in less than 20 countries whereas more than 70 bcm of it is generated in just four of the mentioned countries. Iran flared 400 bcf of gas in 2011. In this paper, five options of Iran's gas flare recovery have been compared via MCDM method. For developing the model, the weighing factor of each indicator an AHP method is used via the Expert-choice software. Two groups of cases were considered in this analysis. One group was designed with priority given to individual indicators, while the other indicators had the same value, and the second group consisted of cases where the priorities were defined always keeping one criterion in first position, while the priorities of the other criteria were defined by ordinal information defining the mutual relations of the criteria and the respective indicators.
