Definitions

  • the invention relates to a method for dispensing liquefied gas as a liquid phase from a source having a gas-liquid mixing phase Contains medium, as well as a device for performing the method.
  • the dosing accuracy is significantly influenced by whether it is to be dosed Medium is completely in the liquid phase, or whether, for example, by a Change of prevailing pressure or available volume of a part the liquid evaporates and thus a gas-liquid mixing phase in the dosing Medium occurs.
  • the gas-liquid mixing phase leads to many technically used dosing systems to some considerable dosing errors and in many cases leaves a continuous Delivery of the medium does not increase as the liquid flow through volumes that Contains gas, is disturbed and may tear off. To disruption of the tax and To avoid dosing, various methods are used, either Tolerate large losses of medium or require a lot of equipment.
  • the most lossy process is the draining of gaseous medium from the plant. This process is not harmless for substances that are harmful to the environment or are very expensive, not applicable. It also uses this procedure only an incomplete separation of the gaseous phase is achieved.
  • the present invention has for its object a method and an apparatus for the economical and low-loss provision and delivery of a dosed amount of liquefied gas is available as a liquid phase with high accuracy to provide, the high accuracy of the dosage, especially at discontinuous delivery of small amounts of liquefied gas is ensured.
  • the heat dissipation can, for example, by a conventional cooling unit, through the evaporation of liquefied gases, or preferably done by a Peltier element.
  • the temperature is set so that the gaseous components condense inside the vessel.
  • Cooling the cooling medium via a Peltier element using a heat exchanger it is recommended, especially for the treatment of small amounts of medium, that Cooling the cooling medium via a Peltier element using a heat exchanger.
  • the specified method is particularly suitable for dispensing small amounts of liquefied gas.
  • the method is intended in particular for the emission of CO 2 .
  • the invention is particularly applicable to media under a prevailing Pressure in the range from 10 to 80 bar, particularly preferably in the range from 64 up to 67 bar.
  • the invention is particularly suitable for dispensing liquefied Gas with a liquid gas mass flow of 0.1 to 2.0 kg / mm, particularly preferred in the range from 0.1 to 1.0 kg / min.
  • the invention can also be used in the field of suction pressure stabilization of high-pressure CO 2 pumps.
  • a device for dispensing liquefied Gas provided, with a discharge point for the liquefied gas with a source in Connection is established, which is a gas-liquid mixed phase medium contains.
  • the task is solved in that between the source and a condensation vessel is interposed in the delivery point, in the gaseous one Portions of the medium are transferred to the liquid phase.
  • the walls of the condensation vessel are expediently designed to be cooled.
  • a cooling chamber is recommended for cooling the walls of the condensation vessel to provide for a cooling medium that surrounds the condensation vessel.
  • At least one heat exchanger is provided, in which the heat dissipation via a Peltier element is ensured that is between the cooling area and the warm area of the heat exchanger is integrated.
  • the cooling area of the heat exchanger is inside, the warm area of the heat exchanger outside described cooling chamber.
  • a condensation vessel a compressed gas bottle, in particular a small gas bottle, is provided.
  • a compressed gas bottle in particular a small gas bottle.
  • the condensation vessel is expediently located in a cooling chamber insulated cylinder installed. especially when using a compressed gas cylinder a cylindrical cooling chamber enables a condensation vessel good flow of cooling medium around the condensation vessel, for example with air.
  • the condensation vessel is with a riser pipe fitted
  • the invention provides an economical and low-loss method of providing and dispensing an amount of liquefied gas dosed with high accuracy as Liquid phase provided, especially for discontinuous delivery small, defined amounts of liquefied gas.
  • the invention offers one whole range of advantages:
  • the invention makes one Little equipment in terms of equipment, compact to build to provide a Liquid phase provided.
  • a liquefaction device according to the invention enables a secure, reproducible liquid gas mass flow, their dosing with high accuracy even when dispensing small and very small quantities can be made. Dosing errors are caused by the invention Method safely avoided, even with a low throughput of liquefied Gas.
  • the invention offers good conditions for integrating the Gas-liquid application in connection with a machine time sequence control.
  • a small gas bottle 1 is shown as a condensation vessel with a riser pipe 2 and position fixation 3 for fastening the small gas bottle 1 in the cooling chamber 4.
  • the inside of the small gas bottle 1 is filled with liquid CO 2 in the lower area 5, and in the upper area 6 there is a gas-liquid mixing phase supplied through the riser pipe 2 and the feed 8.
  • the gaseous portion of the mixing phase condenses. Due to the transition of gaseous components into the liquid phase, the liquid CO 2 increases in the lower area 5 of the small gas bottle 1. From this area, liquid CO 2 is released via a removal point 7 in order to provide a pure liquid phase.
  • the gas small bottle 1 serving as a condensation vessel is cooled by the air flowing in the cooling chamber 4. This air is cooled by means of a Peltier element 9 and heat exchanger 10.
  • the cooling area 11 of the heat exchanger 10 lies inside the cooling chamber 4.
  • the warm area 12 of the heat exchanger 10 is located outside the cooling chamber 4 and ambient air flows through it.
  • the cooling chamber 4 has a housing 13 and an insulating layer 14.
  • the device shown in the figure can also e.g. be rotated by 180 °. Possibly is this installation position due to boundary conditions that arise during integration result in a complete system required.
  • the structure of the invention remains unchanged only the use of the feed 8 and the riser 2, and the so-called tapping point 7 is changed.
  • the so-called tapping point 7 serves to feed the medium.
  • the removal of the liquefied medium is about the riser pipe 2 and the so-called feed 8 made.
  • the invention thus has one Flexibility with regard to their installation position.
