Based on the priciples of cleaning up by absorption and adsorption, there is an optimum removal of pollutants when petroleum substances in liquid are 40% of the total volume of absorbing liquid. The rate of absorbing the styrene waste gas in liquid absorption section was from 74% to 97.6% in a pilot plant while being from 60% to 97.4% in an industrial cleaning plant. Activated carbon can adsorb styrene from the waste gas at a rate of 30% by weight of carbon itself. In an industrial cleaning plant using a combination of the above two processes, the removal of styrene from waste gas can be over 94.8%. The key of such a process is to look for a reasonable absorbing liquid and to design a practical cleaning plant.
