Automobile Emission Reduction with Wet-Scrubber Technology

Abstract

Increasing automobile emission is becoming a major problem to our environment. The available solutions like catalytic convertors, exhaust gas recirculation are costly and energy intensive. This paper examines the viability of the wet scrubber technology to reduce pollutants in the exhaust gas of the engine. This technology is already being used to reduce pollutants in static applications but not in the automobile sector. It passes the exhaust through a suitable solvent which dissolves some of the pollutants. But the problem in using these scrubbers for automobile emission control is their large size and requirement of external source of energy. In this paper a method to modify the wet scrubber technology to suit the automobile industry has been discussed and its effectiveness has been studied. This paper focuses on proving that the wet scrubber technology can be effectively used for treating automobile exhaust gas. It has been experimentally confirmed that the amount of pollutants in the exhaust could be reduced by 10% by using a wet scrubber.
