Title: Analysis of power generation processes using petcoke
Author: Jayakumar, Ramkumar
Abstract: Petroleum coke or petcoke , a refinery byproduct , has generally been considered as an unusable byproduct because of its high sulfur content . However energy industries now view petcoke as a potential feedstock for power generation because it has higher carbon content than other hydrocarbons like coal , biomass and sewage residue . This gives petcoke a great edge over other feedstocks to generate power . Models for the two most common processes for power generation , namely combustion and gasification , were developed using Aspen Plus steady state chemical process simulator . Overall plant layouts for both processes were developed by calculating the heat and mass balance of the unit operations . After conducting wide sensitivity analysis , results indicate that one ton of petcoke feedstock can generate up to 4 MW of net available power . Both processes have rates of return greater than 30 % , although gasification offers a slightly more attractive opportunity than combustion .
