liETHOD AND ARRANGEMENT FOR THE DISPOSAL OF GAS SPACE CONTENTS
OF LARGE-VOLUME CONTAINERS IN THE CASE OF COMPONENTS WHICH
LOAD THE ENVIRONMENT
The invention is directed to a method and an arrangement for disposing of gas space contents of large-volume containers such as tanks or the like when emptying one tank and filling another tank with materials whose gas phase loads and is harmful to the environment or is to be reclaimed as valuable material, wherein the gas space of the tank being emptied is filled with a substitute material and the gas contents of the tank being filled are guided via a cooling trap.
Chemicals are often not only stored in tanks but also transported by means of tank cars, i.e. from the producer to the consumer, from the producer to intermediate storage and from there to the consumer or in another manner, wherein the operators of such tank vehicles are instructed to transport very different products with their vehicles. When such a tank is emptied, volatile materials form in its gas space, often the gas phase of the corresponding products, wherein this gas phase escapes, at the latest, when refilling the tank. It works out in practice that the tanks are opened frequently while being transported in the empty state, so that the surrounding air blows out the harmful gas phase of the components which are then given off into the environment. If the emptying is not complete, it can happen during the refilling of the tank that the product with which the tank is subsequently filled combines in a dangerous way with the gas phase of the previously transported product; this can be not only toxic but also e.g. highly explosive.
On the other hand, the material flowing into the tank being filled drives out the corresponding gas volume from this tank, which gas volume must then escape if the filling is not effected against a developing counterpressure; the so-called gas displacement method is used for this purpose, e.g. when filling gasoline tanks, i.e. the expelled gas volume is redirected into the gas space of the tank vehicle being emptied in order to ensure uniformity of pressure. This gas ~2~
displacement method makes sense so long as a single material is being transported by the tank vehicle.
However, if the product is changed, and this is most frequently the case, since transport containers are rarely always used for the same medium, the gas displacement method no longer works. The gaseous material would contaminate the new material to be transported in the transport container. In the worst case, chemical reactions (explosions) occur. For this reason, the transport containers are rinsed or neutralized when dealing with water-soluble components. This is usually not possible with organic solvents, since the latter are frequently not mixable with water. Moreover, this results in contaminated water which must be disposed of in turn in a costly manner.
This creates the opportunity for criminal action. The transporter will employ the gas displacement method during the emptying process at the location of the client, but leaves open the dome cover in transit so that the head wind removes the gas from the tank. This is strictly prohibited for reasons of environmental protection. However, there is no usable solution, since rinsing with water is usually unsuccessful. Thus, in the case of combustible liquids, an explosive mixture of air and gas can occur which can lead to catastrophe in the event of a spark.
It is the object of the invention to provide a solution with which the gas space contents can be disposed of in a simple manner, wherein the solution is to be effected in such a way that the devices which are used have the smallest possible volume and are simple to manage and can also be used with conventional tank vehicles regardless of whether the latter are road vehicles or rail-bound vehicles.
This object is met, according to the invention, in that the cooling trap is operated with a liquid inert gas, wherein the inert gas operating the cooling trap is used as substitute material for filling the tank being emptied.
2 ~ 6 ~
The proposed filling of the gas space of the tank being emptied with a substitute material on the one hand and the disposal of the gas volume of the tank to be filled via a cooling trap on the other hand has the special advantage that it makes no difference for the tank vehicle being emptied whether or not the product is changed when next used. The substitute material makes the operation of the tank vehicle independent of the transported material. On the other hand, by means of providing a cooling trap, the product which is guided via the cooling trap and then condenses can be supplied directly to the consumer again, so that there is no discrepancy in volume for the consumer with respect to the quantities agreed upon. As in the gas displacement method, emptying and filling can be effected without the occurrence of pressure differences in this case as well.
Moreover, the directing of gases via a cooling trap has the advantage that these materials are condensed out in the cooling trap and can possibly be placed at the disposal of the consumer again, since he shares in the cost of these materials in practice. It is also possible to receive the materials exiting via the cooling trap in containers having a very small volume and to use them for other purposes. A number of materials can be utilized as substitute materials, including in some cases surrounding air entering the tanks.
A method is known from DE-A-12 51 233 by means of which industrial scale vapors can be reclaimed, wherein the vapors are guided via cooling stages. This text does not describe the type of filling or the volumes involved when reclamation is effected, rather the overall disclosure concerns the surrounding air. The reclamation of a gasoline-vapor mixture is shown also in DE-A-23 37 055, in which a gasoline-air mixture is likewise cooled in such a way that the hydrocarbons contained therein are condensed and frozen out.
The special advantage of the present invention consists in that the inert gas with which the gas space is filled is made available as coolant or, conversely, in that the coolant 2 ~ 6 3 --''I--is utilized, after the gas volume has cooled, as an inert gas which fills up the gas space according to corresponding evaporation. In so doing, the invention makes use of the understanding that an environmentally friendly inert gas coolant increases extremely in volume when evaporated.
It is advantageous to use nitrogen as the inert gas operating the cooling trap and filling the gas space in the gas phase.
The use of nitrogen is particularly advantageous, since this is often available in liquid form and the gaseous phase effects an increase in volume from approximately 1 to 800 compared to the liquid phase. Moreover, nitrogen prevents explosions and is also completely harmless to the environment.
Since nitrogen atmospheres do not enter into chemical reactions with air under normal conditions, peroxide formation and the like can no longer come about e.g. with solvents which react with air.
The invention also provides that the cooling trap for the precipitation and condensation of the expelled gases is operated in a temperature range of -10 to 50C. The utilized devices can be constructed so as to be comparatively small with respect to volume in this temperature range, wherein the selected temperatures ensure that e.g. at least 80~ of the solvent cools out below its dew point and can accordingly be reclaimed as condensate.
The highly volatile portion which is not included can then be guided e.g. via an activated charcoal system which can likewise be constructed so as to have a small volume, as is likewise provided according to the invention.
If nitrogen is available in the area of the tanks being processed, the invention likewise provides that the cooling trap is used as a partial evaporator for the substitute gas, particularly for the liquid nitrogen, i.e. the operating medium of the cooling trap is simultaneously the substitute gas.
, The invention also provides an arrangement for carrying out the method which is distinguished by a cooling trap with condensate collector and residual gas cleaner.
An activated charcoal filter, for example, can be used as residual gas cleaner according to the invention.
As already stated in the beginning, different materials are often transported successively in a tank vehicle, so that different residual gas compositions also come about. In this respect, the invention provides that the arrangement comprises a plurality of separately connectable filters for different residual gases.
The invention is explained in more detail in the following by way of example with the aid of a drawing. The single drawing shows a basic diagram of the arrangement according to the invention.
The arrangement, designated in general by 1, substantially shows the connection between a first tank 2 of a tank vehicle 3 and a second tank 4, wherein the outlet connection piece 5 of the tank 2 is connected with the filling connection piece 6 of the tank 4 via a filling line 7.
A eooling trap, designated in general by 8, is provided in addition; liquid nitrogen (N2) flows through its cooling eoils, shown in a sehematie manner, whieh is indieated by arrow 9. The liquid nitrogen whieh heats up in the cooling trap 8 is gasified and enters in the head area 10 into the gas spaee of the tank 2 when the latter is emptied, the gas spaee being designated in general by 11.
The gas eseaping in the gas space 12 of the tank 4 to be filled is directed via a line 13 into the cooling space of the cooling trap 8 and condensed in the latter, and the condensate thus obtained is guided again via a condensate line 14 to the product line 7 and accordingly flows back into the tank 4.
Uncondensed residual gas is given off into the environment via a line 15, wherein an activated charcoal filter 16 can be provided.
-6~
The control and regulating of the entire arrangement is effected in such a way that no pressure difference prevails between the gas spaces 11 and 12 of the two tanks 2 and 4, i.e. the evaporating nitrogen can be supplied either in excess, when greater volumes are needed than would be necessary per se by the operation of the cooling trap, or in deficit, i.e. gasified N2 not required in the gas space 11 is then given off into the environment.
Also indicated is the possibility, designated in general by 16', to provide a plurality of cartridges with different filter fillings according to the material to be processed; the uncondensed residual gas then enters via the line 15 into the respective cartridge 16 needed at the time.
Naturally, the described embodiment example of the invention can be modified in many respects without departing from the basic idea. Thus, the invention is not limited to the spatial arrangement of the cooling trap 8, which is only shown schematically here; this cooling trap 8 can be provided at the face as a securely installed structural component part in the area of the tank 4 and as an integrated component part of the tank vehicle 3 and the like.
