The Research And Application Of Liquefied Petroleum Gas Spherical Tank Adopts Zare Anticorrosion Coating

This paper introduces the present situation of the application of liquefied petroleum gas spherical tank in the petroleum and petrochemical industry and prospect. At present, the application of liquefied petroleum gas spherical tank in petrochemical industry is very broad,but often occurs because of LPG spherical tank corrosion crack, liquefied petroleum gas spherical tank containing defects whether can continue to use has brought great trouble to the enterprise. If you don’t allow any defects exist, that is not the economy, if its existence without analysis, it is dangerous. In recent years, many research institutions at home and abroad have started to appear defect of pressure vessel for safety assessment. At the same time also has a lot of research institutions in the study of corrosion causes of liquefied petroleum gas spherical tank, the search for effective corrosion protection measures. But, in view of the liquefaction of spherical tank, how to choose the suitable safety assessment method and the anti-corrosion measures, it remains to be further in-depth study.This study, from the perspective of the liquefied petroleum gas spherical tank containing defects, to《Safety assessment for in-service pressure vessels containing defects》basis for the evaluation. After assessing the can continue to use this as the research object of LPG spherical tank.To analyze the corrosion reason of liquefied petroleum gas spherical tank, the SCC sensitivity of liquefied petroleum gas spherical tank is high, the causes of the formation of cracks on the spherical tank is wet h2 s stress corrosion environment.Through comparing all kinds of anti-corrosion technology, as well as the practical application of Zare coating on the liquefaction spherical tank, Zare coating can be determined to solve the problem of corrosion of liquefied petroleum gas spherical tank.This article is only to source gas workshop of spherical tank the g-2 is studied, but similar to the running liquefied petroleum gas spherical tank has high reference value. This article did all the work and get the conclusion, safe and reliable operation to ensure the LPG spherical tank has very important significance.
