ARRANGEMENT FOR STORING VISCOUS PETROLEUM PRODUCTS Russian patent published in 1995 - IPC

FIELD: transport. SUBSTANCE: arrangement for storing viscous petroleum products has at least one reservoir with heater communicating with heating unit connected through parallel pipelines with heat transfer agent. The heating unit is provided at least with one recuperative heat exchanging apparatus, one pump and an expansion chamber. The chamber is made in the form of a tank mounted downstream of the apparatus and connected through two pipelines with the main pipeline. The chamber is filled with heat transfer agent in case of volumetric expansion due to heating. Mounted on the pipeline upstream of the pump is at least one filter. The heat transfer agent shall feature low consolidation temperature and may be fed into one or several reservoirs with viscous oil products. The arrangement makes it possible to perform heating of petroleum products directly at the moment, when it is necessary. EFFECT: improved reliability and reduced power consumption for storage petroleum products in reservoirs. 1 dwg
