Process Optimization of Biogas Upgrading with AMP Using Pilot Plant Data and Simulations with Aspen Plus
MetadataVis full innførsel
In gaseous biofuel production mixtures of CO2, CH4 and/or H2 and are typically produced. When using these gaseous for example in fuel cell applications (H2) or as vehicle fuel (CH4) gas upgrading is needed. Upgrading involves removing the carbon dioxide from the gas using conventional post-combustion capture technology. Many technologies have been used for the CO2 removal: water scrubbing, pressure swing adsorption, membrane technology, pressure swing adsorption, cryogenic separation and chemical absorption. In this study the feasibility of chemical absorption using AMP solution is studied. The objective is to study the advantages and disadvantages of different process configurations for biogas upgrading plant using 2-amino-2-methyl-1-propanol (AMP) solution. The work will be performed using ASPEN PLUS simulation tool. The work can be divided into following activities:- Validate the aspen plus model against experimental data.- test different stripper and absorber configurations and the evaluate the energy requirement of them-Optimize "the best" configuration.
