Gas is usually flared because it is thought to bewaste. In the oil and gas industry, flare is an essential safety system, used for the safe disposal of flows from pressure safety valves and depressurization of processing equipment. Researches and studies show that flare has the potential to be a source of energy. It is proven bythe development of the technologies that reuse fcnd recover :the flare gas and use it as source of energy. In the early stage of this project, the characteristic of the flare gas will be analysed. The characteristics that need to be studied are the compositions ofthe flare gas, the heating value for the flare gas. Afterwards, this project evaluate each option that available that can be use to maximize the usage offlare gas. Every option is evaluated referring to the practicability, efficiency, economically and effect to environment. This project will bring up the best solution on how to maximize the usage of flare gas. The results from the analysis of the gas show that flare gas has the similarity of the composition of the natural gas which has referred as the fuel gas for the equipment on the platform. Even though the composition of the flare gas has the similarity of the natural gas, but the value for the heating value differs from the heating value of the flare gas. This is because the difference in the composition of the other component gas in the flare gas has made the difference. To apply the recovery system for flare gas currently is not economical since flare the gas is the cheapest way of handling flare-gas. But then, referring to the trend of the carbon dioxide (C02) emission in Malaysia, it is possible that in the future, Malaysia may need to apply the C02 tax scheme to control the C02 emission. This study will be a good reference for the petroleum sectorto refer to for the flare gas recovery.
