Abstract: The carbon dioxide recovery method and apparatus are capable of reducing regeneration energy and operating cost, and structurally advantageous. An absorber has first and second absorbing sections where a gas is supplied through the first absorbing section to the second absorbing section. A regenerator has first and second regenerating sections. The first regenerating section has an external heater and the second regenerating section is heated by the gas discharged from the first regeneration section. The absorbing liquid circulates between the second absorbing section and the first regenerating section in a circulation system, and a branch system allows a part of the absorbing liquid to flows from the second absorbing section through the first absorbing section and the second regenerating section successively to the first regenerating section. The recovery gas discharged is compressed, and its heat is recovered and supplied to the regenerator by heat exchange with the absorbing liquid.
