    摘要: An electric generating power plant and a method of operation thereof wherein the boiler (1) produces steam to a turbine driven-generator (2), carbon dioxide from combustion exhaust gas emitted from the boiler is simultaneously absorbed in an absorbing solution in an absorber (7), the absorbing solution with the absorbed carbon dioxide is passed through a regenerator (10) where the carbon dioxide is stripped from the absorbing solution, the regenerated absorbing solution is returned to the absorber (7), and steam from either the boiler (1) or turbine of the turbine-driven generator (2) is supplied to a reboiler (13) to provide heat for operation of the regenerator (10). During periods of high demand for electric power steam extraction from the boiler or turbine is discontinued, operation of the regenerator (10) is discontinued and the absorbing solution from the absorber (7) is stored in a first storage unit (15). During periods of low power demand steam is supplied to the reboiler (13) from the boiler (1) or turbine and absorbing solution from the first storage unit (15) is fed to the regenerator (10) for operation thereof, and absorbing solution stripped of carbon dioxide from the regenerator (10) is stored in a second storage unit (16). Absorbing solution from the second storage unit (16) is fed to the absorber (7) during periods of high power demand.

    摘要: An apparatus and a process for removing CO.sub.2 from a combustion exhaust gas, by effecting counterflow contact of aqueous alkanolamine solution with the combustion exhaust gas to absorb CO.sub.2 from the gas in the alkanolamine solution and effecting a further contact of the gas with either, condensate water formed by causing condensation of the gas after removal of CO.sub.2, or condensate water formed by causing condensation of the combustion exhaust gas directly after combustion of the fuel. The apparatus includes a tower (1), a first contact section (2) in the tower through which the exhaust gas flows upwardly in counterflow contact with the aqueous alkanolamine solution dispersed by a nozzle device (7) downstream of the first contact section (2), a second contact section (3) in the tower (1) downstream of the nozzle device (7) for effecting counterflow contact of reflux water from a spent absorbent liquor regenerating tower (28) with the gas after removal of CO.sub.2. The temperature of the aqueous alkanolamine solution to be supplied to the CO.sub.2 -removing tower (1) is adjusted in such a manner that the temperature of the exhaust gas at the entrance (4) of the CO.sub.2 -removing tower and that of the treated gas at the exit (5) of the CO.sub.2 -removing tower are the same.

    摘要: A pull-on absorbent article including a front outer cover to be worn around a wearer's front side, a rear outer cover to be worn around the wearer's rear side, and an absorbent assembly fixed to the front and the rear outer cover so as to bridge them and having a pair of side seals. The length of each of the front and the outer cover in the longitudinal direction of the article is uniform in the lateral direction and larger than that of the side seals so that the front and the outer cover have extension portions that extend downward from the side seals. The extension portions of the front and/or the rear outer cover have an elasticized region extensible in the lateral direction in a region located laterally outward of each side edge of the absorbent assembly.
