Abstract: PURPOSE: A sulfones separation process using two-step absorption which uses methanol as polar solvent is provided to minimize operation cost and energy consumed in the separation during a process of separating sulfones from fraction containing sulfones. CONSTITUTION: Diesel containing sulfones is passed through absorber and then sulfones is absorbed in the absorber. A polar solvent is supplied to the absorber, and the absorber is recycled by dissolving and dissembling the sulfones absorbed in the absorber with the polar solvent. The polar solvent, by which the sulfones is dissolved, is passed through active carbon, and the polar solvent is recycled by absorbing and separating the sulfones dissolved in the polar solvent with the active carbon. Hydrocarbon is supplied to the active carbon in which the sulfones is absorbed, and thus the sulfones is separated from the active carbon. The sulfones is separated and collected from the hydrocarbon by distilling the hydrocarbon in which the sulfones is included. The absorber uses acidified silica. The polar solvent uses methanol. The active carbon is made by increasing surface polarity by activating carbon powder, whose pore size is 0.3-0.6 nm, in the temperature of 800 - 1000°C for 4-6 hours as supplying CO2.

Abstract: PURPOSE: A capturing method of carbon dioxide and device thereof are provided to reduce the compressing cost for transferring ammonia gas, which is collected in an ammonia solution process in which the high pressure carbon dioxide is collected, to the removing tower of high pressure carbon dioxide, thereby increasing the collect rate of ammonia and the removal rate of carbon dioxide in the absorptive tower. CONSTITUTION: A capturing method of carbon dioxide uses an absorptive tower(3), a washing tower(13), a carbon dioxide removing tower(6), and an ammonia collecting tower(15). The absorptive tower selectively absorbs carbon dioxide from the combustion gas by using ammonia absorptive solution. The carbon dioxide removing tower removes the carbon dioxide from the ammonia solution, in which the carbon dioxide is absorbed, at high pressure. The ammonia collecting power separates the ammonia solution produced in the washing tower into the ammonia gas and water. The ammonia evaporating in the absorptive tower is supplied to the washing tower, is washed with cleaning water, and is transferred to the collecting tower. Vapor and ammonia gas mixture produced by being heated in the ammonia collecting tower are transferred to a heat exchanging partial condenser which is located on the top of the ammonia collecting tower. Vapor is condensed in the heat exchanging partial condenser and is recycled into the ammonia collecting tower, and the ammonia gas is recycled to the absorptive tower through an ammonia gas transferring pipe.
