摘要： A wet-type flue gas desulfurization method and plant making use of a solid desulfurizing agent in which exhaust gas exhausted from a combustion apparatus such as a boiler is brought into contact with absorbing liquid to absorb sulfur oxide from the exhaust gas into the absorbing liquid followed by neutralization of the absorbing liquid containing the sulfur oxide thus absorbed. The solid desulfurizing agent is selectively retained in an absorbing liquid neutralizing zone and the absorbing liquid, containing water as a main constituent and solid products formed from the absorbed sulfur oxide, is selectively removed from the neutralizing zone. In the neutralizing zone the upward flow of the absorbing liquid, optionally augmented by an upward flow of air or water, forms a fluidized bed of limestone particles, thereby preventing coating of the limestone by gypsum and thereby retaining reactivity of limestone. According to the present invention, coexistence of Al and F in the absorbing liquid seldom deteriorates the desulfurizing performance. Further, it is possible to reduce power and cost required to grind limestone and to achieve a higher desulfurizing performance.

摘要： An object of the present invention is to provide a CO2 removal apparatus that prevents release of an amine compound of an absorbing solution from a CO2 absorption device. The CO2 removal apparatus includes a desorption column 13 that heats and regenerates an amine compound aqueous solution discharged from a decarbonator 1 making counterflow contact of a combustion exhaust gas and an amine compound aqueous solution; and reflux means that refluxes an amine compound aqueous solution regenerated in the desorption column 13 to the decarbonator 1 via a cooler 19. A contact section that makes counterflow contact of reflux water of the desorption column 13 and a CO2-removed combustion exhaust gas is formed in two stages, and the cooler 19 on the downstream side of the desorption column is also formed in two stages. Reflux water from the first stage cooler is supplied to the first stage contact section, and reflux water from the second stage cooler is supplied to the second stage contact section. As a result, the reflux water from the cooler 19 on the downstream side of the desorption column 13 can be efficiently used for amine removal of the decarbonator 1, and a concentration of an amine released from the decarbonator can be reduced.

摘要： CO is recovered from a CO-containing gas by contacting a CO-containing gas with a non-aqueous CO-absorbing solution comprising 3 to 6 moles/l of hexametaphosphateamine, 1 to 4 moles/l of cuprous chloride, 0.1 to 1% by weight of water and an organic solvent, thereby absorbing CO into the CO-absorbing solution from the CO-containing gas, and then atomizing the CO-absorbed solution, thereby stripping CO from the CO-absorbed solution and obtaining a CO gas, while recycling the CO-freed absorbing solution to the absorption of CO from the CO-containing gas with remarkable reduction in the corrosion rate on apparatus materials without impairing the CO absorption, and use of a two-fluid, simultaneous atomizing means for atomizing the CO-absorbed solution together with the vapor of the organic solvent can improve the CO stripping rate, and reduce the CO recovery cost.

摘要： A fluidized bed combustor wherein a combustion chamber and a regeneration chamber are both contained in a single hollow body is provided. These two chambers are formed by vertically partitioning the body by a partition wall, which has an upper opening and a lower one, and also each have a perforated plate at the bottom part thereof on which a heat transfer medium containing a desulfurizing agent is placed and fluidized. The desulfurizing agent is transferred from the combustion chamber through the lower opening to the regeneration chamber and circulated by overflow through the upper opening again to the combustion chamber. Various modifications of the above-mentioned fundamental embodiment are proposed. Combustion and desulfurization are automatically and effectively carried out in a single apparatus to give a high percentage desulfurization, make the apparatus compact, and reduce the initial cost and the running cost thereof.
