Title: Utilizing the heat content of gas-to-liquids by-product streams for commercial power generation
Author: Adegoke, Adesola Ayodeji
Abstract: The Gas -to -liquids (GTL ) processes produce a large fraction of by -products whose disposal or handling ordinarily becomes a cost rather than benefit . As an alternative strategy to market stranded gas reserves , GTL provides middle distillates to an unsaturated global market and offers opportunities to generate power for commercial purposes from waste by -product streams , which normally are associated with increased expenses incurred from additional handling cost . The key concept investigated in this work is the possibility of integrating the GTL process with power generation using conventional waste by -product steam streams . Simulation of the integrated process was conducted with the aim of identifying the critical operating conditions for successful integration of the GTL and power generation processes . About 500 MW of electric power can be generated from 70 % of the exit steam streams , with around 20 to 25 % steam plant thermal efficiency . A detailed economic analysis on the LNG , stand -alone GTL , and Integrated GTL Power -Generation plants indicates that the integrated system is more profitable than the other options considered . Justifying the technology and economics involved in the use of the by -product streams to generate power could increase the net revenue and overall profitability of GTL projects . This technology may be transferable to GTL projects in the world , wherever a market for generated power exists .
