ZARE技术在含硫化物液态烃球罐的应用

Application of ZARE Technology in Spherical Tanks for Sulfur Hydrocarbon Liquid

液态烃球罐发生应力腐蚀开裂,主要是由于湿硫化氢发生电化学反应造成。针对含硫化物的液态烃球罐在国内石化领域检测发现大量腐蚀裂纹,提出防止球罐应力腐蚀的一项专有ZARE技术,旨在预防和降低液态烃球罐发生应力腐蚀开裂的风险,降低液态烃球罐的使用风险,ZARE技术本质属于阴极保护技术,已在国内10家炼化企业使用,取得了初步成效,ZARE技术有望在国内炼化企业推广使用。

The culprit of stress corrosion cracking in spherical tanks for liquid hydrocarbons is the electrical-chemical reaction of wet hydrogen sulfides.To solve the problems of large number of SCC found in the examination of spherical tanks for sulfur hydrocarbon liquid,a dedicated proprietary ZARE technology was proposed to prevent and reduce the risks of SCC on spherical tanks for hydrocarbon liquid so as to minimize the risk in spherical tank operation.The ZARE technology,which is the cathodic protection technology,has been successfully applied by more than 10 refiners in China,and good results have been achieved.The technology will be widely appreciated in Chinese refineries.
