Reduce Emissions and Save Energy by Converting Flared Gases into Fuel Gases

Abstract

Energy management and fuel conservation are crucial for controlling emissions and enhancing profitability of today’s oil and gas industries. Many organization are pursuing flaring and emission reduction initiative as part of their energy management system thereby minimizing operating cost and liberation of harmful greenhouse gases to the environment. This paper presents a flaring and emission reduction initiative implemented at ADNOC Gas Processing natural gas liquids (NGL) fractionation plants in Ruwais. The design limitations on spent gas piping system leading to loss of valuable of fuel gas resources were recovered by enhancing the capability of the system. Following is the list of actions completed to implement the initiative:Feasibility study for utilization of flared spent regeneration gases as fuel gases for boilersUpgradation of spent gas piping for sour serviceApplying an innovative non-linear fuel blending controller The successful implementation of the initiative by in-house team resulted in an impressive flaring reduction of 60% and a reduction of CO2 emissions of 62,700 Tons/annum.
