摘要

PROBLEM TO BE SOLVED: To provide a method for preventing the corrosion of a sulfuric acid tank, and to provide a sulfuric acid tank which has excellent corrosion resistance.;SOLUTION: The local corrosion of steel for welding structures in contact with the gas-liquid boundary of a sulfuric acid tank conveying or storing sulfuric acid with a concentration of ≥70 mass% is prevented. In this method for preventing the corrosion of the sulfuric acid tank, on exhaust of loaded sulfuric acid, air is blown from a position within 10% of the height of the sulfuric acid liquid in the full load condition from the floor face of the tank into the sulfuric acid. The sulfuric acid tank having excellent corrosion resistance is provided with a means of blowing air from a position within 10% of the height of the sulfuric acid in the full load condition from the floor face of the tank into the sulfuric acid, or consists of steel having specified components.;COPYRIGHT: (C)2003,JPO
