The accelerating pace of climate change regulatory action has rendered it necessary to understand the potential impact of carbon constraints on unconventional hydrocarbon resources such as gas-to-liquids (GTL). A systematic evaluation approach was applied to a GTL plant: 1. Estimate carbon dioxide (CO2) emissions from a GTL plant. 2. Determine the cost of CO2 capture with retrofit, conventional facilities. 3. Determine the CO2 capture cost for alternate technology, oxy-firing plant heaters. 4. Determine the cost of CO2 capture integrated into the original design. Results from stages one through three are included. The capital and operating costs of the capture technologies are compared.
