LPG atmospheric low-temperature storage tank list tank tank holds 5000 ~ 200000m
3, because single tank tank holds large and safety, reliable, it is one of large scale storage LPG mode that low-temperature atmosphere-pressure stores.
LPG atmospheric low-temperature storage tank is in running, and because of factors such as charging, thermal loss, barometric pressure reductions, can produce boil-off gas (BOG), this part boil-off gas, through compressor supercharging, enters collecting tank within the condenser after condensation, temperature about 30 ~ 45 DEG C.Common process sends BOG lime set back to atmospheric low-temperature storage tank again, this part BOG lime set will be lowered the temperature in flash distillation, produce boil-off gas (BOG), cause circulation compression and the condensation of boil-off gas (BOG), the not only capacity of equipment of increase BOG compressor, condenser, and the power consumption of BOG compressor, the energy consumption of condenser also increase thereupon.
Model utility content
The purpose of this utility model is to provide a kind of LPG atmospheric low-temperature to store and Pressure of Ambient Temperature associating storage device, and this device not only reduces the ability of the equipment such as BOG compressor, condenser, also reduces the energy consumption of BOG compressor power consumption and condenser.
The technical solution of the utility model is: a kind of LPG atmospheric low-temperature stores and Pressure of Ambient Temperature associating storage device, it is characterized in that: comprise LPG atmospheric low-temperature storage tank and LPG Pressure of Ambient Temperature storage tank, compressor, condenser, collecting tank and shifting pump is provided with successively between LPG atmospheric low-temperature storage tank and LPG Pressure of Ambient Temperature storage tank, transfer pump entrance is connected with LPG Pressure of Ambient Temperature storage tank, outlet is connected with removing the pipeline outside battery limit (BL), in atmospheric low-temperature storage tank, be provided with pump in tank, in tank, pump discharge connects the pipeline gone outside battery limit (BL).
LPG atmospheric low-temperature storage tank comprises the complete anti-tank of the anti-tank of metallic walls list, the two anti-tank of bimetal wall, the two anti-tank of prestressed concrete outer tank, the complete anti-tank of bimetal wall, prestressed concrete outer tank, and single tank tank holds 5000 ~ 200000m
3.
LPG Pressure of Ambient Temperature storage tank comprises spherical tank, horizontal or vertical pressure vessel, and single tank tank holds 500 ~ 5000m
3.
BOG compressor can be mazy type reciprocating compressor, also can be horizontal opposition type reciprocating compressor.
Condenser can be air cooling device, also can be water cooler, or the combination of air cooling device string water cooler.
The utility model has the advantage of the group technology that LPG atmospheric low-temperature stores and Pressure of Ambient Temperature stores, significantly can reduce the ability of BOG compressor and condenser, reduce equipment investment, also reduce the power consumption of BOG compressor and the energy consumption of condenser simultaneously, save operating cost.
