Abstract :

Background and Purpose: In the last hundred years, to reach more manufacturing, supplying and consumption, using fossil fuel increased in industries, such as refineries, petrochemical and industrial complexes, etc. which spread severely environmental pollution worldwide consequently. The pollution as a complex problem has many reasons and also leads many negative effects, including environmental concerns, economic cost and fatal impact to human health. One of the most important cause is flare gas of industries. According to the world statistics, Iran is considered as third largest position in burning flare gas. A huge reduction in emission of these gases is one of the main goals to be achieved with the help of all international communities. Materials and Methods: Hence different methods such as gas to liquid seems necessary as one option to recovery the flare gas. In this study, the data related to flare gas of a particular refinery with the help of simulation software Aspen Hysys, the GTL unit isanalyzed. Results: The simulation shows that when the flare gas used as a raw material to unit GTL, it will be achieved 1549 GTL product barrels per day. Discussion and Conclusions: This case study shows that one of the most important flare gas recovery method is GTL.
