Specific implementation process:
One, embodiment 1: the propylene (take spherical tank ST-302C as example) in the Propylene recovery spherical tank.
1, the propylene discharging is switched to, ST-302A, B stop discharging.
2, when the ST-302C liquid level reaches 2 meters (17%) stops the discharging of C tank, switches the ST-302B discharging.
3, close ST-302C terminal valve and ST-302A, B gas-liquid equilibrium tube valve.
4, open cold condenser chilled water valve behind the tank car material inlet valve, notices that control enters condenser propylene pressure and is not more than 1.2MPa, will control simultaneously tank car pressure (coming balance pressure with tank car gas phase pipe) well, and the assurance liquid propene can enter tank car.
5, opening compressor takes out negative pressure to ST-302C and advances ST-302A, B to the charging house steward.
6, the pressure as Propylene Spherical Tanks ST-302C is lower than 0.2MPa, stops compressor.
7, connect industry water with flexible pipe and be connected to spherical tank bottom valve valve, open industry water, spherical tank is intake.When spherical tank pressure (PIA-301C) is 0.4MPa, start compressor, when the spherical tank liquid level is 10 meters, stop into industry water.When PIA-301C pressure is 0.1MPa, stop compressor.
8, connect dispatch notification can pressure release the time, open Propylene Spherical Tanks emptying (valve opening speed should slowly increase, emptying speed should control approximately " 8M/S has the people to monitor in 100 meters on the periphery when emptying, in prospective vehicle does not enter, forbids emptying in the thunderstorm weather situation).
9, when spherical tank pressure is zero, disconnect valve HC-301C, LISA-301C and C tank balance tube valve and blank off.
10, like this, the propylene in the Propylene Spherical Tanks ST-302C all reclaims complete.
Two, embodiment 2: the propylene in the Propylene recovery pipeline.
1, prepare propylene tank car A, the B of two skies, and the tank internal pressure is not higher than 0.4MPa, send usefulness as propylene outer tube back-pressure.
2, close the charging modulating valve of B/C spherical tank, and manually-operated gate 5., 6., 9., 10., (11), (12).
3, the rapid pipe joint (DN50) of 9. valve being located metallic hose is connected to the discharging outlet port of tank car A, and the rapid pipe joint (DN25) of the metallic hose that valve (12) is located is connected to the gas phase entrance of tank car A.
4, nitrogen pressure is brought up to 1.7-1.8 MPa when oil refinery send nitrogen, in advance the propylene outer tube is carried out feeding liquid under pressure goal tank C.Judge whether to stop force feed according to difference of liquid level and pressure difference before and after the force feed.Throttle down 7., 8..Open valve 9., utilize self pressure of propylene outer tube that propylene is pressed into tank car.
5, start propylene compressor, tank car is taken out negative pressure.
6, (if the pressure of propylene outer tube (oil refining factory and office) is less than 0.6MPa), the oil refinery related personnel thinks that pressure is lower, can lead to nitrogen, nitrogen (pressure 1.4MPa) valve of then notifying oil refinery to open the acrylic tubing place is pressed into the propylene in the outer tube in the propylene tank car A.
7, when the tank internal pressure of tank car A reaches the 0.8MPa left and right sides, open valve (11) and (12), then start propylene compressor, the propylene gas in the tank car tank is pressed in the spherical tank by balance tube.
8, according to the pressure rising range in the tank car A tank, whether need to change another tank car.
If 9 need to switch to another tank car, then stop propylene compressor, throttle down (11) and (12), 9. and (13) throttle down again, to in time pull down rapid pipe joint, and this joint is connected on the B tank car, open valve after connecting 9. and (13), continue the propylene in the outer tube is pressed into the B tank car.
10, same, when the tank internal pressure of tank car B reaches the 0.8MPa left and right sides, open valve (11) and (12), then start propylene compressor, the propylene gas in the tank car tank is pressed in the spherical tank by balance tube.
11, force feed is opened the little valve (14) that drains at tank car B discharge opening place after a period of time, sees that the gas that ejects is nitrogen or propylene.
If 12 what emit is to contain a large amount of propylene, then continue force feed.
If 13 emit just contain a small amount of propylene gas, then can notify oil refinery to stop nitrogen (pressure 1.4MPa) force feed; Stop simultaneously propylene compressor.
14, the notice oil refinery is opened nitrogen (pressure 0.7MPa) valve at acrylic tubing place, 9. while also opens valve and (13), open valve (11) and (12), throttle down (15), (17), (18), (19), (20), open valve (16), with force feed gas through tank car from the emptying of A tank top.
15, after purging a period of time, little valve (a 14) sample analysis that drains at tank car discharge opening place.Also contain more propylene if analyze, then continue to purge; If only contain micro-propylene, then can stop to purge.
16, like this, the propylene in the propylene pipeline all reclaims complete.
The utility model does not limit to above-mentioned preferred forms, and anyone can draw the propylene recovery unit in other various forms of a kind of Propylene Spherical Tanks and the pipeline under enlightenment of the present utility model.All equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
