Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Accompanying drawings the specific embodiment of the present invention, as shown in Figure 1, butadiene turnover goods and storage at lower temperature system, comprise multiple spherical tank, canned motorpump p, rock gas gas compressor t and valve;
Described each spherical tank comprises liquid phase and to stock up pipe yj, liquid phase shipment pipe yc, gas phase pipe q;
Described spherical tank is stocked up and is responsible for yjz by stock up pipe yj and liquid phase of liquid phase and is connected, and the liquid phase supervisor yjz that stocks up is connected with the pump that harbour unloads on freighter;
Described liquid phase shipment pipe yc is connected with liquid phase shipment looped pipeline ycf by canned motorpump p, and liquid phase shipment looped pipeline ycf is responsible for ycz with liquid phase shipment and is connected, and liquid phase shipment supervisor ycz is connected with loading groove tank;
Liquid phase shipment looped pipeline ycf also stocks up with liquid phase and is responsible for yjz and is connected;
Described gas phase pipe q unloads pump on freighter respectively by gas phase supervisor qz with harbour, loading groove tank is connected;
Described gas phase supervisor qz is access rock gas gas compressor t in parallel also;
Described rock gas gas compressor t is also connected with liquid phase shipment looped pipeline ycf.
Also comprise heat exchanger b, access heat exchanger b in parallel on liquid phase shipment looped pipeline ycf;
Each pipeline is provided with corresponding valve.
Concrete mode of operation is:
One, to unload a ship in spherical tank butadiene operation from harbour:
Butadiene liquid utilizes the pump on ship directly to deliver to the spherical tank of needs from the harbour direction liquid phase supervisor yjz that stocks up, and the liquid phase opened on this spherical tank is stocked up pipe yj valve, as the spherical tank a that stocks up, opens va3, va4; Several spherical tank is stocked up simultaneously, then open the valve on these spherical tanks simultaneously;
If the gas pressure in spherical tank is too high, the pump on ship does not enter butadiene, then valve va5, va6 on the gas phase pipe q opening this spherical tank, open valve v1, v3, v19, the v18 on gas phase supervisor qz again, close v7, return a part of butadiene gas on ship, reduce pressure and can continue unloading.
Also step-down can be carried out by rock gas gas compressor t, open valve va5, va6 on spherical tank gas phase pipe q, open valve v18, v7, v30, close v19, through rock gas gas compressor t, open v32, v29, v27, v34, v6, v17, v5, stock up through liquid phase and be responsible for yjz, the liquid phase opening other spherical tanks is again stocked up pipe yj valve, arranges into corresponding spherical tank.
If rock gas gas compressor t outlet temperature is too high, then close v34, open v24, through heat exchanger b, after heat exchange cooling, open v22, v20, v17, v5, stock up through liquid phase and be responsible for yjz, the liquid phase opening other spherical tanks is again stocked up pipe yj valve, arranges into corresponding spherical tank, reduces pressure and can continue unloading.
Two, spherical tank cooling process during butadiene storage:
Open liquid phase shipment pipe yc valve va1, va2 of the spherical tank a that need lower the temperature, open valve v9, v10, open valve v11, v12, close v6, start canned motorpump p, open v24, through heat exchanger b, after heat exchange cooling, open v22, v20, v17, v5, va3, va4 and get back in original spherical tank a, can butadiene in circulation temperature lowering cooling spherical tank a to safety temperature.Also the butadiene after cooling can be stored in other any spherical tanks, only need open corresponding spherical tank and to stock up valve.
Three, spherical tank carries out tank switching and tank-cleaning operation:
Tank switching: liquid phase shipment pipe yc valve va1, va2 of opening the spherical tank a that need need to pour in down a chimney, opens valve v9, v10, opens valve v11, v12, v6, starts canned motorpump p, opens v17, v5, enters in other spherical tanks from the liquid phase supervisor yjz that stocks up.
Clear tank: in spherical tank a butadiene liquid phase conductively-closed pump p install, but also have butadiene gas in spherical tank, open valve va5, the va6 on the gas phase pipe q of spherical tank a, open valve v18 on gas phase supervisor qz, throttle down v19, open v7, v31, v32, v29, start rock gas gas compressor t, open v28, v26, can butadiene gas be put in groove tank car by gas phase supervisor qz, thus as far as possible the butadiene amount in spherical tank is dropped to minimum, then replaced by water-filling or nitrogen, reach tank clearly.
Four, loading operation is carried out from spherical tank to groove tank car or ship:
Car loading operation, opens liquid phase shipment pipe yc valve va1, va2 of spherical tank a, opens valve v9, v10, open valve v11, v12, v6, starts canned motorpump p, closes v17, opens v8, can load in groove tank of tank car by liquid phase shipment supervisor ycz;
If groove tank internal pressure is too high, canned motorpump p can not get through, then open gas phase supervisor qz valve v2, v3, v18, v19, open valve va5, va6 of the gas phase pipe q of spherical tank a again, return a part of butadiene gas in spherical tank a from the gas phase mouth of groove tank, the pressure reduced in groove tank can continue car loading operation;
Ship-loading operation, close v8, open v17, v4, by liquid phase stock up supervisor yjz can load onto ship, if ship overpressure, canned motorpump p can not get through, then open valve v1, v3, v18, v19 on gas phase supervisor qz, open valve va5, the va6 on the gas phase pipe q of spherical tank a again, return a part of butadiene gas in spherical tank a, the butadiene gas pressure reduced in cabin can continue ship-loading operation.
If the butadiene temperature of shipment or car loading operation pump discharge is too high, then can opens and closes after corresponding valve is lowered the temperature by heat exchanger and be transported in groove tank or in cabin.
