Abstract
The removal of CO2 from gas streams can be achieved by a number of separation techniques including absorption into a liquid solvent, adsorption onto a solid, cryogenic separation, and permeation through membranes. Among these techniques absorption into a liquid solvent is the most suitable process for a high volume of synthesis gas streams. This chapter is devoted to the energy assessment of carbon dioxide removal in an existing Integrated Gasification Combined Cycle (IGCC) plant based on an oxygen blown entrained flow gasifier operating at 27 bar, removal of acid gas (H2S) in a MDEA unit, and a 53% efficiency combined cycle. A carbon dioxide separation process conveniently integrated in a pre-combustion separation is chosen in order to take advantage of the high pressure of the gas. In the first step six appropriate CO2 removal systems are selected from existing processes in industrial area. In the second step, simulations are performed for the six CO2 separation processes, using the Aspen Plus™ software. In the third step three processes are selected and integrated, as realistically as possible, to the IGCC. Finally, energy consumption is analyzed and overall efficiency of the IGCC with CO2 capture is evaluated.
