  7. Abstract:
  8. The Increasing trend of gas flaring over oil fields and gas process systems in Iran not only causes several environmental problems, but makes the economical resources useless as well. Considering the high amount of flaring and old facilities, one of the best solutions is the recovery of the flare gas in Iran. It seems that collecting the flare gas is not possible in different sectors. Therefore, using a plant for converting flare gas to other products must be logical. In this project, the feasibility study of converting flare gas to other products is studied. For this reason, a methanol plant is simulated; whose input feed is the content of flare gas of the South of Iran (Marun and Siri). After capital cost and total product cost are estimated, the payback period and net present value are also appraised according to two scenarios: with considering the environmental taxes and without considering environmental issues. The payback period is evaluated around 4 years for Marun and 6 years for Siri. Consequently, the sensitivity analysis is employed on economical and technical data. The results show that the flow rate of input gas and also the percentage of methane in it have a great influence on profitability of the plan. In addition, by implementing environmental taxes in the country, the possibility of performing the plan is more practical in Iran
