Simulation of liquefied petroleum gas recovery from off gases in a fuel oil refinery

Abstract

With the growing need and demand for petroleum fuels in the industrial, automotive and domestic sectors, it has become the need of time to address this problem. The important question is, what engineers can do in this regard. There is a simple solution to cater this problem, the production trends worldwide are increasing every year, but still, the demand keeps increasing exponentially. One way is to stress emphasis on reducing the wastage of these precious fuels and, at the same time, implement methodologies and techniques to recover these. The research caters to cope up with the shortage of LPG within Pakistan. Since LPG is a fuel that is being used in the industrial, automotive as well as domestic sector, adequate responsive measures should be taken to meet the market requirements. This research focuses on the technique to recover LPG from refinery off-gases. Since off-gases usually are flared of by most of the refineries leading to potential loss of lighter end fuels like LPG. The article encloses a detailed proposal of a recovery plant that makes use of simple techniques and efficient process accompanied by economical and feasible solutions.
