Definitions
- the liquefied petroleum gas industry uses a large number of portable tanks for the distribution of these gases; during the life of these packages, it is necessary to remove the valve or the valve equipping them for operations such as periodic retest, dent removal, defective valve change.
- the present invention is directed to a method and an installation for emptying liquefied petroleum gas cylinders, suppressing any emission of liquefied petroleum gas into the atmosphere by allowing recovery or reuse of the liquefied petroleum gas which has been removed bottles.
- nitrogen and carbon dioxide can be used in particular.
- the pressure of the inert gas is, in general, between 1.5 and 3 bar although higher pressures can be used.
- the bottle of liquefied petroleum gas can be cooled to be emptied in any suitable manner.
- a convenient way is to immerse in a bath of a liquid at low temperature and leave it there for a bottle with a capacity of 13 Kg for a period of between 5 and 10 min.
- the bottle Once the bottle emptied of liquefied petroleum gas and filled with inert gas, it can either store it or make it undergo various operations before filling it again.
- the withdrawn gas can be sent directly to the annealing furnace of the liquefied petroleum gas bottles with, in this case, preferably the interposition of an anti-flame device.
- Liquefied petroleum gas can also be sent to a tank.
- the conveyor is a roller conveyor, inclined by 1 to 5 degrees from the cooling station to the discharge station, so that the bottles in side-by-side contact go down along the inclined plane while remaining the time. necessary in the tank, the descent being carried out step by step because the bottle the most downstream is out of the tank.
- the conveyor does not need drive means at a low temperature. But the conveyor can be as horizontal and pushes the bottles after the bottle downstream has been removed from the tank
- magnets are placed in the conveyor or under the conveyor in the tank, to overcome the hydrostatic pressure and to keep the bottles on the conveyor.
- the installation can be according to claim 5.
- the installation comprises an insulated tank 1 comprising an inlet 2 of brine at -10 ° C. and an outlet 3 of this same fluid which, conveyed by a pump 4, passes into a refrigeration unit with heat exchange to return to the tank 1 through the inlet 2.
- roller conveyor 4 inclined by 3 ° from the portion to the inlet 2 to the portion to the outlet 3.
- bottles B butane gas at 20 ° C under a relative pressure of 2 bar.
- the first bottle B at the entrance is placed at the top in the bath, it will move from right to left in the drawing until below a position 6 of unscrewing the tap of the bottle B, the travel time of the bottle on the conveyor 4 until it comes below the station 6 is 6 min.
- the valve unscrewing station 6 the bottle B is sufficiently cooled so that the remaining butane gas is at a temperature of -8 ° C while being in liquid form at atmospheric pressure.
- the valve of the bottle B is unscrewed at the position 6 of unscrewing.
- the bottle B is open, butane does not come out, since it is in liquid form.
- the bottle B then passes under a delivery station 7 comprising a device sealingly applied to the neck 8 of the bottle and having an orifice 9 communicating with a source 11 of nitrogen at a pressure of 1.5 bar and a rod 11 to the bottom 12 of the bottle and communicating with a use 13 of gas.
