This paper presents the results of an evaluation of advanced combined cycle gas turbine plants with precombustion capture of $CO2$ from natural gas. In particular, the designs are carried out with the objectives of high efficiency, low capital cost, and low emissions of carbon dioxide to the atmosphere. The novel cycles introduced in this paper are comprised of a high-pressure syngas generation island, in which an air-blown partial oxidation reformer is used to generate syngas from natural gas, and a power island, in which a $CO2$-lean syngas is burnt in a large frame machine. In order to reduce the efficiency penalty of natural gas reforming, a significant effort is spent evaluating and optimizing alternatives to recover the heat released during the process. $CO2$ is removed from the shifted syngas using either $CO2$ absorbing solvents or a $CO2$ membrane. $CO2$ separation membranes, in particular, have the potential for considerable cost or energy savings compared with conventional solvent-based separation and benefit from the high-pressure level of the syngas generation island. A feasibility analysis and a cycle performance evaluation are carried out for large frame gas turbines such as the 9FB. Both short-term and long-term solutions have been investigated. An analysis of the cost of $CO2$ avoided is presented, including an evaluation of the cost of modifying the combined cycle due to $CO2$ separation. The paper describes a power plant reaching the performance targets of 50% net cycle efficiency and 80% $CO2$ capture, as well as the cost target of 30\$ per ton of $CO2$ avoided (2006 Q1 basis). This paper indicates a development path to this power plant that minimizes technical risks by incremental implementation of new technology.
