Abstract

PURPOSE: To prevent evaporation loss of oil, inflammation trouble, etc., by placing a pressure gauge etc. under a fixed roof and controlling water pressure so as to constantly bring the roof into close contact with oil, in an oil-water replaceable tank for storing crude oil etc. solid at normal temp.
CONSTITUTION: An oil-water replaceable tank for storing, in solid state, crude oil, heavy oil, etc. solid at normal temp. is filled with water, and then a predetermined amt. of a liquid oil is introduced via distributer 6 and stored by replacing the water. A vapor zone formed with solidification and shrinkage of the liquid oil, is detected by pressure gauge or stress gauge 8 placed under the roof 2, and pressure control valve 9 is automatically opened corresponding to the signal of detection, applying a required pressure on water tank 3 from pressure medium tank 10, so that the oil is raised and brought into close contact with the roof 2, making the vapor zone disappear. Thus the oil is prevented from vaporizing.
