FIELD: transport, package.
SUBSTANCE: invention relates to method of packing bitumen in disposable packages to it to be carried in cold state. Proposed method consists in fabricating disposable packages from flexible plastic material with melting point varying from 20° to 50°C above bitumen softening point. Prior to packing, bitumen is cooled down to bitumen softening point. Plant intended for implementation of said method, incorporates plate-type heat exchanger wherein temperature difference between cooling medium and bitumen at heat exchanger outlet makes 10 to 25°C, preferably from 15° to 20°C. Proposed plant comprises also return pipeline branched off upstream of filling gate valve and runs back into store vessel. To keep up constant temperature, said plate heat exchanger is provided with electric heating elements.
EFFECT: possibility to select package that can melt with bitumen without affecting bitumen quality.
