Abstract

The larger contributor of the Greenhouse Gas (GHG) emissions sources is the power generation sector with a percent of 24% of all greenhouse gas emissions, the most important greenhouse gas being the carbon dioxide. Coal utilization for generating energy is regarded with concern because of the higher amount of greenhouse gas emissions. Greenhouse Gas (GHG) emissions can be considerably reduced by combining Integrated Gasification Combined Cycle (IGCC) with Carbon Capture and storage, having near-zero CO2 emission. The base design of this plant is an entrained-flow gasifier with water quench (Siemens), water-gas shift conversion of CO, a modified Acid Gas Removal (AGR) system using Selexol which captures in addition to hydrogen sulphide also carbon dioxide, Pressure Swing Absorption (PSA) for the purification of hydrogen and a combined cycle gas turbine (CCGT) based on Mitsubishi gas turbine (M701G2), running on hydrogen-rich gas. The cases presented in this paper will produce about 400 MW net electricity. This paper investigates power generation with carbon capture and storage through cogasification of coal and biomass. This paper focuses on plant configuration and the evaluation of key performance indicators and the CO2 specific emissions. The process modeling and simulation will be conducted using the process flow modeling software ChemCAD. The data collected will be used to complete performance evaluation of hydrogen and electricity co-production processes based on co-gasification of coal and biomass with carbon capture and storage.
