By using a combustion flue gas () from a power turbine (), a high-pressure secondary compressed air (C) is subjected to heat exchange in a first heat exchange unit (A) of an exhaust heat recovery device (), and by using resultant heat-exchanged flue gas (A), a low-pressure primary compressed air (A) is subjected to heat recovery in a second heat exchange unit (B) of a saturator (). Then, a primary compressed air (B) that has been subjected to heat recovery in the second heat exchange unit (B) is introduced into a secondary air compressor () to increase the pressure of the air, and then the high-pressure air is subjected to heat recovery in the first heat exchange unit (A), producing a secondary compressed air (D). The secondary compressed air (D) is introduced into a combustor () and combusted using fuel.

A methanol synthesis column and a gasoline synthesis column synthesize gasoline from the reformed gas via methanol and produce a liquid fuel. A superheater superheats a part of low-pressure steam that has been heat-recovered from the reformed gas with a part of middle-pressure steam that has been heat-recovered by the methanol synthesis column or the gasoline synthesis column, and the steam thereby brought into an unsaturated state is supplied to a low-pressure steam turbine.

A method or system for recovering carbon dioxide is provided with which in a plant for synthesizing methanol from a hydrocarbon gas or synthesizing gasoline therefrom via methanol, the waste heat of a low-temperature reformed gas, which has conventionally been discarded and is difficult to reutilize, can be effectively utilized. In the system for synthesizing methanol or gasoline from a hydrocarbon gas and for recovering carbon dioxide, a reformed gas is produced by steam reforming of the hydrocarbon gas. Since a combustion discharge gas generates when a fuel gas is burned in order to obtain a heat source for the steam reforming, carbon dioxide is recovered from the combustion discharge gas in an absorption tower () using an absorption liquid. In a regeneration tower (), the reformed gas is used first as a heat source for a first reboiler (A) located at the tower bottom, and the reformed gas having a lowered temperature is then used as a heat source for a second reboiler (B) located in a middle position to heat the absorption liquid in stages, thereby regenerating the absorption liquid.

A drawing amount of the flue gas by the blower to the carbon-dioxide collecting device is increased until an flow rate of the flue gas from the stack becomes zero in the gas flow sensor, and when the discharged amount of flue gas from the stack becomes zero, drawing in any more than that amount is stopped, and the carbon dioxide in the flue gas is collected while the flue gas is drawn in by a substantially constant amount.
