Abstract

A method of heating and dispensing bitumen in an above-ground bitumen storage tank and bitumen terminal is that bitumen is heated. Bitumen is heated in the storage tank. Bitumen is heated in a casing installed in the tank with an intake and drainage pipe. Heated to a temperature of in-plant transportation at least 80° C. In the main storage tank volume bitumen is heated and maintained by heaters. This takes place outside the shell with the intake and drain pipe. Heating takes place at a temperature not lower than the flow temperature of 60° C. A method of heating and dispensing bitumen in an above-ground bitumen storage tank and bitumen terminal is that bitumen is heated. Bitumen is heated in the storage tank. Bitumen is heated in a casing installed in the tank with an intake and drainage pipe. Heated to a temperature of in-plant transportation at least 80° C. In the main storage tank volume bitumen is heated and maintained by heaters. This takes place outside the shell with the intake and drain pipe. Heating takes place at a temperature not lower than the flow temperature of 60° C. Feed bitumen from the volume under the casing with the intake and drain pipe of the storage tank to the main volume of the working tank is carried out as the bitumen is discharged from the working tank. Bitumen in the working tank is heated in a casing installed in it with the intake and drain pipe. Bitumen is heated to a working temperature of not less than 140° C. Bitumen is heated with subsequent release to external transport or in the technological process. In the main volume of the working tank, outside the housing with the intake and drainage tube, bitumen is heated to a temperature not lower than 80° C. for in-plant transportation of bitumen. Bitumen heating is maintained by heaters.
