在油田老区改造工程中，旧储油罐大修的难题在于清理，以往对旧储油罐清洗采用的是喷砂或高温高压水射流的方法。这些方法产生大量废水，排放时给周围环境造成污染，也给二次处理造成了很大困难。用这些方法工作时，水汽弥漫，尘土飞扬，劳动环境很差，容易对工作人员身体健康造成伤害。用干冰清洗技术清洗旧储油罐能有效解决这些问题，清洗出来的原油等污染物，可直接清除并及时拉运指定地点，形成落地原油再利用，没有任何有害物质产生，效果良好。

In the revamping of old oil fields, it is very difficult to clean the old oil tanks in the overhaul. The conventional sand blasting or HP water jet for oil tank cleaning will produce a large amount of waste water which will pollute the environment when discharged, and impose a great difficulty in secondary treatment. In addition, the water vapor and floating dusts in sand blasting and HP water jet operations are hazardous to the health of operators, The application of dry ice cleaning technology can effectively solve the above problems in cleaning the old oil tanks. The oil and wastes cleaned out can be transported to the designated place for treatment or disposal. The waste oil can be reutilized and no hazardous materials are produced, Good results are achieved.
