Definitions

  • the invention relates to a method for the safe transport of dangerous liquids and / or gases, in particular oil and / or combustible gases.
  • Liquids such as oil and natural gas
  • tanker or through pipes to the consumer countries Large-scale ships are used for this type of transport.
  • the contents of these ships cannot be brought completely to safety in the event of an accident.
  • the oil that runs out damages animals and nature.
  • the solution to the problem is that the transporter, in particular the tanker, the wagon or the container, is filled with an absorber and this is saturated with the liquid and / or the gas to be transported and then the transport takes place and the saturated absorber at the destination conveyed into a separation device and there the liquid and / or the gas is thermally separated and passed on for further processing and the absorber agent thus regenerated is recovered.
  • the process enables light and heavy fuels to be transported safely.
  • the separation takes place during the regeneration of the absorber and the subsequent refining. It is thus possible to carry out a pressure-free transport of combustible gases, the absorber surface preferably being saturated with the gas beforehand, after which the capillary spaces can still be filled with liquid.
  • activated carbon granulate it is possible to store up to 280% of the weight of the raw absorber in foreign substances.
  • the loading and unloading of the transporter is easily possible because of the granular shape of the absorber means with known conveying devices, namely belts, paternosters and in particular with fluidizers in pipes.
  • Inert gas is preferably used for the fluidization, for which purpose nitrogen or carbonic acid or a mixture thereof is suitable.
  • a flammable gas can also be used as long as the transport of saturated absorber material is to be carried out.
  • a protective function is guaranteed by inert gas, which also applies during transport, with a slight overpressure possibly preventing air from entering the bunker or the container.
  • the separation of the absorber at the target location from the liquid or the gas is expediently carried out in a known manner by heating and, if appropriate, by centrifuging and under reduced pressure.
  • Coarse-grained expanded clay and, in particular, fine-grained activated carbon which consists, for example, of cylinder bodies with a length of 2 mm and a diameter of 1 mm, has proven to be an effective absorber.
  • An advantageous device allows crude oil to be continuously separated into its lighter and heavier components by moving the absorber mass on a conveyor belt through a container which is divided into an upper and lower region by the porous conveyor belt and from above with the raw absorber and is loaded with crude oil, which is discharged saturated on the conveyor belt with the light portion, so that the heavier oil portion passes into the lower container area and can be removed from there.
  • This heavy oil component which can be transported relatively safely, can then be packed separately in barrels or bunkered.
  • the liquid or oil impregnation device comprises a container, as a liquid or oil container, and a conveyor belt, which is partially in the container.
  • the part of the conveyor belt running in the container is preferably partially horizontally guided.
  • the somewhat liquid-permeable conveyor belt is arranged in such a way that its horizontal and inclined part runs centrally in the container, dividing it up in height. Therefore, in the case of a conveyor belt in the usual form, the floor plan is adapted to the container and, if necessary, is square.
  • a corresponding amount of absorber mass is fed into the container from a conveyor so that it is continuously poured onto the horizontal part of the conveyor belt working in the container.
  • Oil is poured onto the absorber mass from a pipe above the container. This sucks the liquid up to saturation and is carried out of the container by the conveyor belt.
  • the excess, generally viscous, heavier liquid is passed through the conveyor belt to the lower part of the container and is led out through a discharge pipe.
  • the saturated absorber mass moving out of the container is advantageously to be packed in sacks or containers and is therefore easy to transport as a non-liquid material.
  • a possibly somewhat viscous, non-absorbable part of the oil that is led out of the drain pipe is also easy to transport in drums or in small tankers, or it is returned diluted with light, liquid material.
  • the absorber mass can be used repeatedly as the absorber mass after regeneration, with the liquid being expelled.
  • the return trip of the means of transport offers an inexpensive return transport of the absorber mass.
  • An absorber mass which is preferably selected to contain silica consists of a silicon-containing granulate, such as Aerosil, or clay-containing spheres, such as expanded clay or the like. Activated carbon pellets of small dimensions in the millimeter range are preferably used as the absorber material.
  • Oil separation during regeneration is preferably carried out by heat, the adsorbed substances being gasified and passed directly into the distillation columns or crackers. None changes in the usual oil quality and refinery forms.
  • the regenerate is preferably with Conveyor belts are conveyed back into the transporter or tanker.
  • the liquid or oil impregnation device can be set up for general use for the transport of dangerous goods, but especially in the oil-producing countries and in the export ports of states or private shipping companies or institutions, and can be used to facilitate and favor transport and to protect the environment.
  • the simplest way to saturate the absorber is to introduce the liquid into the containers that are filled with absorber material.
  • Tankers in particular carry the absorber material on the way to the oil port instead of a water ballast. This eliminates the pumping of the ballast water when refueling and the costly disposal of the oil-contaminated ballast water.
  • FIG. 1 An apparatus for the invention is shown in FIG. 1.
  • FIG. 2 A process diagram is shown in FIG. 2.
  • Fig. 1 shows a perspective of the oil soaking device (1), partially opened and cut.
  • the device (1) advantageously consists of a rectangular container (1) into which the liquid (2), preferably oil, is poured from an overhead tube (12).
  • a conveyor device (13) also guides an absorber mass (3) into the container (11).
  • the two mass guide channels (12, 13) are set up so that they land on a conveyor belt (14) which is flat in the container (11).
  • the somewhat liquid-permeable conveyor belt (14) is arranged in the container (11) in such a way that it carries the granular absorber mass (3) and at the same time enables part of the liquid (2) to be sucked up by the absorber mass (3).
  • the non-absorbed liquid (2) flows through the conveyor belt (14) into the lower part of the container (11).
  • the container (11) On the bottom side, the container (11) has a channel (15) which guides the viscous remaining liquid (2) for further processing and / or for removal.
  • the granular absorber mass (3) which is relatively soaked with liquid (2), is transported to the outside of the container (11) by the conveyor belt (14).
  • the absorber mass (3) can advantageously be filled into liquid-impermeable sacks or barrels and transported therein.
  • Fig. 2 shows a schematic transport process for oil and combustible gas.
  • the oil line or gas line is connected to the distributor line of the Tanker (S) connected, whose bunkers are filled with the absorber mass (A).
  • Gas (G) and / or liquid (F) is then introduced up to the limit of the absorptive capacity of the absorber (A).
  • the tanker (S) with fluidizers with inert gas (I) are discharged via pipes (R) and the saturated absorption mass (A) is fed to a separation device (TV), which separates the expelled liquid (F) and the gas ( G) in a refinery (R), and from which the regenerated absorber (A) is returned to the tanker (S).

Abstract

Selon un procédé de transport sûr de liquides et/ou de gaz dangereux, notamment de pétrole et/ou de gaz combustibles, le transporteur (S), notamment un pétrolier, wagon ou fût, est rempli d'un milieu absorbant (A) qui est ensuite saturé du liquide (F) et/ou du gaz (G) à transporter, puis transporté. Au lieu de destination, le milieu absorbant saturé (AG) est introduit dans un dispositif séparateur (TV) dans lequel le liquide (F) et/ou le gaz (G) est thermiquement séparé, puis soumis à un traitement ultérieur. Le milieu absorbant (A) ainsi régénéré est récupéré.
