TECHNOLOGY AND INSTALLATION FOR PURIFICATION AND NEUTRALIZATION OF ACID GASES
Abstract
A clean environment is an indispensable human right. Economic and technological development leads to pollution of both the air and water. This article presents a method for purifying gases from technological processes contaminated with acids. The absorption apparatus is a packed bed column. Packed bed columns have a large contact area between gases and liquid streams, which allows for absorption at low hydraulic resistances of 10-15 mm water column. The packing used is a honeycomb with vertical walls made of ceramic material, which has very high acid resistance and a long service life. The liquid is evenly distributed over the filling by an liquid distributor, followed by a redistribution layer of bevelled Raschig rings. A solution of (NaOH) is selected for absorption.
