The practical treatments of environment conditioning and inhibitors for corrosion controlling are described. It is in principle possible to prevent corrosion by the removal of corrosive agents or by the addition of inhibitive agents. Desicants are used to reduce relative humidity which is the most important factor of corrosion in gas phase. In aqueous systems the environments can be made less aggressive by removal of dissolved oxygen, adjustment of pH, or deionization. Inhibitors are classified as volatile, water soluble, or oil soluble. Environment controls to reduce corrosion in boiler water systems, cooling water systems, and petroleum refining processes are also given.
