DEVICE FOR STOPING VISCOUS OIL PRODUCTS Russian patent published in 1998 - IPC

FIELD: materials handling; storage and transportation of oil products in tank farms and refinery plants located in regions with high level of solar radiation. SUBSTANCE: to reduce energy losses by using heat of solar radiation, device for storage of viscous oil products is provided with at least one reservoir with heater communicating with heating unit through pipeline with heat carrier connected in parallel and at least one pump, filter and expansion chamber installed on heating unit. Heating unit is provided with at least one solar collector with at least one standby heat exchanger installed behind. Required number of solar collectors is selected depending on heat requirements. Solar collectors can be mounted on nonoccupied roofs of underground reservoirs. Heat carrier with low solidification point is used, and it is not to be drained from solar collectors in winter time. EFFECT: enlarged operating capabilities. 1 dwg
