Process for the total or partial recirculation of gaseous effluents from pelleting towers

摘要

This process requires the total or partial pre- purification and cooling of the gaseous effluents, it being possible to carry out the purification and cooling operations separately or simultaneously, purification taking place via the dry or wet route. In the latter case, purification may be carried out by contact of the effluents with water or with aqueous solutions of the same product which is being pelleted. <IMAGE>
