Removal of sludge formed within crude oil tank
专利汇可以提供Removal of sludge formed within crude oil tank专利检索，专利查询，专利分析的服务。并且PURPOSE: To remove efficiently sludge deposited around the bottom plate of a tank, by supplying crude oil having a specific gravity larger than that of the sludge to a crude oil tank, and dissolving with stirring the sludge coming up to the surface of the curde oil.
CONSTITUTION: Crude oil having a specific gravity larger than that of formed sludge, such as Venezuela crude oil having a specific gravity of 0.9318, is gently supplied from the bottom of a tank into the tank in which crude oil is stored so as not to mix the crude oil stored in the tank with the added crude oil. The crude oil to be supplied is used in an amount equal to or larger than that of the formed sludge. After the sludge has come up to the surface of the added crude oil, stirring is carried out by a mixer provided on the lower side plate of the tank to dissolve the sludge.
EFFECT: The available components of the sludge dissolved in the curde oil can be recovered in a refining stage.
