Push for sustainability is evident in areas such as energy generation where the focus has been on finding new deposits to outpace drawdown on existing reserves. Gas flaring is employed by oil and gas industries to burn-off associated gasses from refineries, hydrocarbon processing plants or oil and gas reserve wells. It is one of the most taxing energies and environmental problems challenging the world today. Generally, safety flaring was dubbed as the saviour of process plants and mostly covers for sudden or unplanned plant trips. It is an opportunity to cut greenhouse gases (GHGs) from oil and gas processing plants through flare gas recovery (FGR) process. Oil and gas plants can employ diverse FGR procedures to offset key concerns about the environmental bearing of GHGs emanation most of which necessitating novel apparatus and extraordinary outlay of design and construction. In this study, apart from economic aspects, a real-life case study is extensively analysed to highlight exploration and adoption of optimizing FGR that may be beneficial if flare gas can be recovered, instead of burning. The output of the study may have a significant impact for refineries towards both economic and sustainability towards greening. In a nutshell, this study highlights the efficacy of reducing ‘flare gas system’ towards environment-friendly ‘greening’ aspect as the core of designing.
