Abstract

The abatement of emission gases, such as SOx, NOx, and COx, is one of the main problems studied by researchers for continuous developments, necessitating considerable investments by several industries. Currently, the scrubber system with its use form, and the chemical precipitation method that is considered as an alternative, are the two different processes that have demonstrated the best results for emission abatement. In this chapter, an assessment is performed on an industrial scale for both the processes, their comparative advantages are discussed, and possible applications presented.

Introduction

Currently, in several industries, there are environmental regulations to control emission and various preventive measures have been realized according to the process structure. As solutions to the emission problem, till date, several processes have been developed. For emission abatement, the ease of use of the proposed process, and the energy and expense entailed are most important topics that require attention. Therefore, most proposed emission abatement methods in the industry currently, are mist eliminator processes that contain scrubbers. In a mist eliminator system, the emission gases in the source are sent to multiperforated layers after they condensed to known density values. Over the last 20 years, mist eliminators have been implemented for emission gas abatement in the petroleum and fertilizer industries. There are several examples of mist eliminator implementations that are used for COx, NOx, and SOx abatement. The removal of sulphur dioxide from the reaction ambience using mist eliminators is an important abatement process1. For the elimination of emission gases, such as SOx, NOx, and COx, several processes have been developed and in recent years, process developments have gained momentum (Wesley et al., 2000).
