Abstract
Flare gas emission is a critical issue in the oil and gas industry due to its significant environmental impacts. One of the most common methods to use flare gases is to convert them into valuable products such as methanol, gasoline, power, and etc. The process of converting flare gas to gasoline (FGTG), consists of 5 units: 1) Flare Gas Sweetening unit, 2) Sulfur Recovery unit, 3) Synthesis Gas Production unit, 4) Methanol Synthesis unit, 5) Methanol to Gasoline Converting unit. Suggested New schemes for the conversion of flare gas to gasoline, in order to reduce greenhouse gases and increases productivity, can include the combined membrane–reverse water gas shift reaction (Membrane + RWGS) unit or reverse water gas shift reaction unit without separation membrane (RWGS) recommended besides of (FGTG) unit. Finally, the Initial model will be compared with the two new models. The results show that by sensitivity analysis the FGTG process with the Combined membrane–reverse water gas shift reaction unit has the highest productivity and the highest energy consumption compared to other models.
