Flare Gases Management with Recovery Methods Utilization

Considering the process of industrial growth in the world and need to consume more of fossil fuels in the industry, including refineries, petrochemicals, etc, one of the energy management requirements is mainly on optimized structure of industrial units and recovery of flare gases. Simulation can be one of the main strategies for technical and economical evaluation of the various phases of the study. The economic evaluation which demonstrates profitability of the project is essential beside technical evaluation to make the right decision. In this paper, according to the Techno–economical evaluation of the proposed solutions, compression method with pay-back period of 3 years is the first choice. Gas to liquid conversion with pay-back period of 4 years and power generation from flare gas with 9 year pay-back period are recognized as the second & third options respectively.
