摘要： Liquid hydrocarbon storage tanks are cleaned by transferring the most contaminated lower fuel layer to an external vessel on a treatment truck where separation into a contaminants portion and a fuel portion occurs. The remnant fuel in the storage tank is cleaned by multiple passes through an external circuit on the truck. The fuel from the vessel is sometimes returned to the remnant fuel to be cleaned. The contaminants are discarded. The initial separation shortens the cleaning cycle. A flexible dip tube stiffened by a guide rod allows probing of the storage tank floor.
摘要翻译： 通过将污染最严重的下部燃料层转移到处理车辆上的外部容器中进行清洁，其中分离成污染物部分和燃料部分。 储罐中的残余燃料通过卡车上的外部电路的多次通过进行清洁。 来自船舶的燃料有时返回到待清洁的残余燃料。 污染物被丢弃。 初始分离缩短了清洗周期。 由导杆加固的柔性汲取管允许探测储罐地板。
