The present invention provides a multi-component composite film comprising a) polymer support layer, and b) porous gellable polymer layer which is formed on one side or both sides of the support layer of a), wherein the support film of a) and the gellable polymer layer of b) are unified without the interface, a method for preparing the same, and a polymer electrolyte system applied the same.

Multi-component composite film method for preparing the same

Disclosed is an exhaust gas treating system having an exhaust gas treating apparatus for carbon dioxide capture process which additionally removes harmful substances remaining in the gas discharged from the existing flue-gas desulfurization process by using separation membrane so as to efficiently carry out the carbon dioxide capture process. The exhaust gas treating system using polymer membrane, comprises a carbon dioxide capture equipment for capturing carbon dioxide from the exhaust gas of a boiler, a flue-gas denitrification equipment placed between the boiler and the carbon dioxide capture equipment, a dust-collecting equipment and a flue-gas desulfurization equipment.

Exhaust gas treating system using polymer membrane for carbon dioxide capture process

Disclosed are an exhaust gas treating apparatus and a treating method for a carbon dioxide capture process, in which harmful substances remaining in the exhaust gas discharged from the conventional flue-gas desulfurization process are additionally removed for efficient performance of the carbon dioxide capture process. According to the exhaust gas treating apparatus for a carbon dioxide capture process, it has the effects of minimizing the installation space of desulfurization equipment and reducing the process cost. In addition, by keeping the contaminants contained in the gas introduced in the carbon dioxide capture equipment below a proper level, absorption performance can be improved as degradation of the absorbent used in the carbon dioxide capture process is prevented. After all, it has an advantage of preventing the pollution by the exhaust gas discharged into the atmosphere.

The present invention provides a multi-component composite film comprising a) polymer support layer; and b) porous gellable polymer layer which is formed on one side or both sides of the support layer of a), wherein the support film of a) and the gellable polymer layer of b) are unified without the interface, a method for preparing the same, and a polymer electrolyte system applied the same.

Disclosed herein is a process for removing sulfur dioxide (SO) and nitrogen oxides (NO) from flue gas using chlorine dioxide (ClO). In the process, chlorine dioxide is allowed to react with flue gas in an alkaline solution so as to be able to simultaneously remove sulfur dioxide and nitrogen oxides from the flue gas. In the simultaneous removal of sulfur dioxide and nitrogen oxides from flue gas using the process, chlorine dioxide is produced by side reactions, and the produced chlorine dioxide can be used to remove sulfur dioxide and nitrogen oxides from flue gas.
