Sourav, Sagar (2012) Production of hydrogen enriched SYN-gas by absorption method. BTech thesis.
Hydrogen-enriched syngas, HESG, addresses two dominant energy and environmental issues: decarbonization and improved energy management. Reducing the CO2 content of syn-gas widens our efforts to build a bridge to an ultra-low carbon world. With HESG, it becomes possible to reduce emissions, improve the efficiency of end-use equipment, and lower the overall carbon intensity of syngas in the years to come. Higher CO2 content in the syngas also lowers the calorific value. This work is aimed at reducing the CO2 content in the syngas by absorption process. For this purpose we have taken the help of ASPEN PLUS simulator. The rate-based non-equilibrium, RateFrac, model is used for column design. Mono ethanolamine (MEA) is taken as liquid solvent and various parameters like flow rate and temperature of the solvent and number of segments of the absorption column were varied to test the CO2 absorption efficiency of the solvent. Similarly CaO absorption efficiency was found by experimental methods for gasification process carried out under different conditions like variation in temperature, equivalence ratio and steam to biomass ratio. The efficiency was found to be less than 30% due to ineffective fluidization.
