Development and analysis of two novel methods for power generation from flare gas

•The conditions of gas flaring in a real gas refinery plant were measured.•We developed two feasible scenarios to reuse the flare gases.•Engineering Equation Solver tool is used to investigate the two studied scenarios.•Burning flare in gas turbine as a mixture with natural gas showed better performance.•Sending flare to middle stages of Gas Turbine was preferable for lower than 0.8kg/s.
