    Abstract: PURPOSE: An apparatus for processing exhaust gas and a method for preventing environmental contamination are provided to minimize the generation of wastewater by neutralizing the ammonia of a small amount which is discharged without absorbing to sulfuric acid. CONSTITUTION: A unification line(17) merges an exhaust gas line to one line. A absorptive tower(20) receives exhaust gas which comes out through the unification line and reacts the exhaust gas with water or deionized water. The water or a deionized water injection line is installed on the upper side of the absorptive tower. The water or a deionized water injection line injects the water or the deionized water to the inside of the absorptive tower. A neutralizing tank(24) neutralizes ammonia gas which comes out through the exhaust gas line of the upper side of the absorptive tower.

    Abstract: PURPOSE: Method and apparatus for continuously eliminating exhaust gas from a light emitting diode manufacturing process using a wet type scrubber and a catalytic reaction scrubber are provided to collect ammonium sulfate generated by neutralization reaction and to re-sell the ammonium sulfate. CONSTITUTION: A method for continuously eliminating exhaust gas from a light emitting diode manufacturing process includes the following: ammonia is eliminated from exhaust gas using a wet type scrubber; hydrogen is combusted and eliminated from the exhaust gas using a catalytic reaction scrubber. During the ammonia eliminating process, ammonia from the lower tank of the wet type scrubber is reacted with a neutralizing solution. The neutralizing solution is one or more selected from water, deionized water, sulfuric acid, nitric acid, and hydrochloric acid.
