Ecological features of carbonate deposit removal from the surface of manufacturing equipment

Abstract

The paper examines the kinetics and mechanism of calcite dissolution in different рН. The diagram of ions distribution subject to the state of medium is given. The simulation of the kinetic curves of dissolution subject to the structure of dual electrical layer and acid-base characteristics of calcite has been carried out.

Keywords
