摘要

Heavy hydrocarbon oil having a pour point higher at least than the environmental temperature is loaded into a storage vessel in a state heated up to a temperature above its pour point and is cooled down to a temperature below the pour point to be stored in a solidified form in the vessel. In unloading the heavy hydrocarbon oil stored in the solidified form in the vessel, the upper portion of the oil in the vessel is heated up to a temperature above its pour point, and the successively fluidized oil portions are pumped out of the vessel.
