Definitions

  • a process and apparatus for purging gas storage tanks comprises generating a gas inert with respect to the stored gas, displacing the stored gas in the tank with part of the inert gas and admixing another part of the inert gas with the stored gas displaced from the tanks, whereby in the case of combustible stored gas explosive mixtures are avoided.
  • the inert gas may be generated by burning a portion of the stored gas or another fuel.
  • the invention relates to a process and apparatus by which storage tanks holding gases (charging gases), particularly combustible gases which are able to form explosive mixtures with a purging gas or air, are freed from residual gas or air by displacement of the charging gas by means of a gas inert with respect to the charging gas.
  • gases particularly combustible gases which are able to form explosive mixtures with a purging gas or air
  • the purging of the containers or tanks of the charging gas, more especially combustible gases, is carried out in a simple manner and in such a way that any nuisance to the surrounding areas and the danger of explosive mixtures being formed is prevented.
  • the invention is characterised in that only a part of the gas produced by a gas generator and inert with respect to the contents of the container is used after cooling and drying for displacing the contents of the container, while the other part after cooling is admixed in sufficient quantity with the residual gas displaced from the container.
  • With combustible charging gases it is advantageous for a part of the gas displaced from the container to be used as combustible gas for the generation of the inert gas.
  • the generated inert gas is used in two different ways.
  • the inert gas not only serves for displacing the charging gas from the containers, but a part of the generated inert gas is directly mixed with the discharged charging gas and as a result the charging gas may be brought with certainty below the danger or explosion limit and be discharged in this state into the atmosphere.
  • these operations can also be carried out in harbour. It is no longer necessary for the ship to go offshore or put to sea for the purpose of changing loads.
  • With combustible charging gases a
  • part of the charging gas is simultaneously used for generating inert gas and is in this way made harmless and is utilised in a very advantageous manner for changing the load.
  • the combustible charging gas is already so diluted that it can no longer be brought to combustion, it is possible for another fuel kept in supply to be used for generating the inert gas.
  • the heat necessary for vaporising the liquefied gas is derived indirectly from the products of combustion (smoke gases).
  • a CO -free inert gas necessary for displacing ammonia gas may be produced by the smoke gases generated by combustion being washed with water with addition of ammonia gas.
  • the water-soluble ammonium carbamate formed by reaction of the ammonia gas with CO contained in the inert gas is washed out of the gas or absorbed by the ammoniacal liquor.
  • the Co -free inert gas, after being dried, is conducted into the tank for displacing ammonia.
  • the generator serving to produce the inert gas comprises a burner and a washing arrangement for scrubbing the gaseous products of combustion.
  • the charging gas and/or a separate fuel are supplied to the burner.
  • the upper end of the washing or scrubbing arrange ment communicates with a mixing unit, to which the charging gas is supplied, it being possible for the gas to be mixed with the cooled inert gas and thereafter released into the atmosphere.
  • a pipe leads from the upper end of the scrubbing unit to the container or tank, so that the generated gas which is inert with respect to the charging gas can be used as displacement gas. It is expedient for a drying unit to be connected in this pipe.
  • an inert gas generator 2 Associated with one or more tanks 1 containing a charging gas is an inert gas generator 2.
  • the latter comprises a burner 3, which communicates with a scrubber and condenser unit 4.
  • the unit is provided with a scrubbing arrangement, for example, a scrubbing tower 5 and a scrubbing water sump 6 including a discharge pipe 7.
  • the scrubbing water is supplied through the pipe 8.
  • Extending from the container 1 to the burner 3 is a pipe 9, and air for combustion is introduced into the mixing chamber 11 through the pipe 10.
  • a pipe 13 leads to the pipe 9 and to the burner 3, it being possible for the pipe 13 to extend through the scrubbing water sump 6. At this position a heat exchanger 14 or a vaporiser surface is arranged.
  • a by-pass pipe 15 from the scrubbing water sump 6 to the upper part of the scrubbing tower 5 is provided and a pump 16 is arranged in the pipe 15.
  • a heat exchanger 17 can be arranged in this pipe for transferring the heat to a medium contained in the pipe 18.
  • a pipe 19 leads from the pipe 9 to the lower part of the scrubbing tower 5.
  • a pipe 20 which leads to a compressor 21 and from thence to a mixing unit 22, from which a pipe 23 extends into the atmosphere.
  • a pipe 24 Connected to the upper part of the scrubbing tower 5 is a pipe 24, in which is arranged a compressor 25.
  • This pipe 24 has a branch connection to a pipe 26, which leads to the mixing unit 22, and to a pipe 27, which communicates with a container or tank 1 holding the charging gas.
  • a drying unit 28 is preferably arranged in the pipe 27.
  • the combustible gas is conveyed through the pipe 9 to the burner 3, the valves 30,31 and 33 being closed.
  • the products of combustion generated by the burner 3 which are in the form of a gas inert with respect to the charging gas are cooled in the scrubber and cooler unit, i.e. by means of the scrubbing tower 5, scrubbing water being supplied through the pipe 8 to the scrubber tower 5.
  • the cooled inert gas is drawn off through the pipe 24, by means of the compressor 25. Some of the inert gas then passes through the pipe 26 to the mixing unit 22, to which, after opening the valve 30, some of the charging gas is supplied through the pipe and the compressor 21. From the latter, the mixture is blown off into the atmosphere through the pipe 23, the mixture being below the explosion limit.
  • the inert gas can be generated in either a reduced pressure or a high pressure atmosphere depending upon whether the compressor is installed following or preceding the combustion chamber, seen in the direction of flow. As long as the combustible charging gas still has a sufficient concentration for burning during the displacement process, the charging gas is utilised for generating the inert gas. When the fuel concentration is no longer sufficient, fuel is supplied partially or wholly from the storage unit 12 through the pipe 13 to the pipe 9, so that inert gas can be generated until the last residue of the charging gas is driven out of the container 1.
  • the power of the burner and the capacity of the scrubbing tower in relation to the capacity of the following drying unit are preferably so adapted that it is possible for some of the displaced waste gases from the container to be so mixed with some of the inert gas which is generated in the inert gas generator but which is not dried that the gas mixture, mixed with atmospheric air, is unable to become explosive and the other part of the generated inert gas, after the drying, is conveyed into the tank for displacing the charging gas.
  • the charging gas is ammonia
  • some of the ammonia gas is supplied through the pipe 19 to the lower part of the scrubbing and cooling unit 4 and the scrubbing tower 5, respectively.
  • a reaction of the carbon dioxide which is in the smoke gas with the ammonia to form ammonium carbamate results, which is washed out of the smoke gas or is absorbed by ammoniacal water in the scrubbing tower 5 as a water-soluble substance.
  • the smoke gas is freed from C0, and can be conveyed into the container 1 through the pipes 24,27, after having been dried in the drying unit 28, for the purpose of displacing ammonia.
  • the inert gas generator 2 makes it pos sible for the displaced gas to be cleansed from watersoluble components through the pipe 19 in the scrubber of the inert gas generator if the burner is kept inoperative. After drying, this gas can be condensed in a reliquefaction plant.
  • liquefied gas is used as fuel, this has to be transformed into the gaseous state before being burned in the gas burner of the inert gas generator 2.
  • the heat exchanger or evaporator 14 located in the scrubbing water sump 6. This evaporator 14 is heated by the heated cooling water of the scrubbing tower 5 serving to heat the fuel which is flowing in the pipe 13 and which is thereby converted into the gaseous state.
  • the by-pass pipe 15 permits the heat of combustion in the generation of inert gas to be utilized.
  • the heated cooling water discharging from the scrubbing unit 5 can be drawn off by means of the pump 16 and conveyed through a heat exchanger 17, in which the heat is given off to another medium in the pipe 18. Consequently, the inert gas generator can be used as heating source for an open or closed hot water circuit, for example, for heating up the charging gas or the like.
  • the gases from the charging tank 1 can be subjected to all kinds of different processes by means of the inert gas generator 2, for example, they can either be washed or burned to form inert gas, whereby a safe removal from the tank takes place. At the same time, it is possible to produce a mixture of inert gas and charging gas, which is harmless and can thus be discharged into the atmosphere.
  • the portion of the inert gas which is in the pipe 24 and which flows to the pipe 27 is preferably in the ratio of about 50 50. The ratio can also be varied within wide limits by means of the valves 39 and 40, if this is necessary.
