Description: The rising price of both natural gas and carbon emission credits are fuelling interest in the use of landfill gas as a substitute natural gas. Pressurized water absorption to remove carbon dioxide from a biogas mixture was selected as the primary upgrading technology by the financial supporters of this thesis for a landfill site in Regina, Saskatchewan. The proposed system was modeled using the OLI Environmental Simulator Program (ESP 7.0). Mass and energy balances were generated and used to size process equipment. An economic model was used to compare process design options. The process was shown to be the most profitable when operated at the lowest temperature and highest pressures simulated. The water absorption technology was compared to a new solar reforming technology on the basis of greenhouse gas emission reductions. The solar reforming technology was shown to have the lowest net Greenhouse Gas emissions of the examined processes.
