Anti-corrosion construction of energy storage tank

What types of corrosion occur in storage tanks?

The main types of corrosion that occur in storage tanks on islands and coastal areas are electrochemical corrosion, which includes crevice corrosion, pitting corrosion, selective corrosion and intergranular corrosion. Electrochemical corrosion is the corrosion caused by the reaction of metals in an electrolyte solution to form a cell.

How to prevent corrosion of steel in oil and water storage tanks?

Cathodic protection methods, coatings and corrosio n inhibitors can be efficiently employed to inhibit the corrosion of steel in oil and water storage tanks. This paper describes new technology, which makes possible effective employment of different combinations of protection methods to prevent corrosion of the bottom and tops of the storage tanks.

What is the corrosion rate of crude oil storage tanks?

In storage tanks for crude oil, for example, the aqueous solution at the bottom contains sulfide ions (H2S) and the pitting corrosion rate can increase to 3 mm/year [1, 2, 4, 5, 6, 8, 13]. Obviously, reliable and efficient corrosion protection systems are necessary.

Can corrosio N inhibitors prevent corrosion in oil and water storage tanks?

Paper presented at the CORROSION 2002, Denver, Colorado, April 2002. Cathodic protection methods, coatings and corrosio n inhibitors can be efficiently employed to inhibit the corrosion of steel in oil and water storage tanks.

What are preventative actions to minimize engineering failure of storage tank bottoms?

Conclusions Preventative actions to minimize engineering failure of storage tank bottoms such as under deposit corrosion, microbial corrosion and stray current corrosion includes inhibitor usage, coating application, ICCP or a combination thereof.

How microbial strains can be used to reduce tank corrosion?

W. J. Santos et al. combined cathode protection system with boundary idea for anti-corrosion methods. 3.4. Biological Desulfurization Technology tank corrosion. Therefore, microbial strains can be used to red uce sulfur content in storage medium in order to reduce tank corrosion.
