Definitions
- the invention relates to a method for separating a gas component from a gas mixture by freezing.
- the invention further relates to an apparatus for performing the method. From the publications DE 35 18 283 C2 and DE 196 35
- a method of the type mentioned is also known from DE 34 22 417 AI.
- a cold trap with a freezing section is provided.
- the gas is forced to intensive heat and material exchange with the cooling or condensation surfaces due to long dwell times and very large cooling surfaces.
- the cooling surfaces are formed by sheets running generally transversely to the gas flow direction.
- the cold trap has no constrictions that tend to clog.
- the temperature is monitored over the freezing section and regulated in such a way that the saturation temperature of the component to be frozen out prevails at the gas inlet thereof and the saturation temperature corresponding to its desired residual concentration prevails at the outlet. Between an essentially linear temperature profile is provided.
- temperature sensors are provided on the cooling plates and a step-by-step control of the route by means of coolant flow and additional heating with intermediate thermal insulation stages.
- the known method requires a relatively high level of equipment.
- the object of the invention is to provide a simple method of the type mentioned in the introduction, in which the component to be separated is obtained completely and with high purity.
- the object of the invention is also to provide a device with which the method can be carried out virtually continuously.
- the object is achieved by a method with the features of the main claim and by a device with the features of the secondary claim.
- Advantageous configurations result from the jerk-related claims.
- the gas component having the lowest vapor pressure is separated from a gas mixture.
- the vapor pressure of the other (other) components in the gas mixture should be significantly higher than the lowest vapor pressure mentioned above. The process can then be operated particularly well and economically.
- a working temperature should be chosen so that the vapor pressure of the gas component to be separated is close to zero. The separation of the gas component with the lowest vapor pressure can then be operated particularly economically. A high technical effort is not necessary.
- An example of a sophisticated gas mixture is a mixture of xenon and oxygen with 70% by volume xenon and 30% by volume oxygen. At a working temperature of 78 K, the vapor pressure of the gas component xenon is approx. 10 ⁇ 3 mbar and is close Zero in the aforementioned sense. The vapor pressure of the gas component oxygen is 228 mbar at 78 K and is therefore significantly higher than that of xenon in the aforementioned sense.
- the gas mixture is exposed to the working temperature.
- the partial pressure prevailing at the working temperature (or the partial pressures if three or more gas components are present in the gas mixture) of the gas component which is not to freeze out is kept lower than the vapor pressure (prevailing at the working temperature) of this gas component. This prevents this gas component from condensing or freezing out.
- the oxygen partial pressure of the oxygen component must therefore be kept below 228 mbar if the gas mixture is exposed to a working temperature of 78 K according to the method.
- a working temperature of 78 K can be achieved inexpensively by cooling with liquid nitrogen.
- the oxygen partial pressure should in particular be less than 200 mbar during freezing out in order to reliably achieve the desired result.
- the gas component to be separated freezes out.
- the other gas component or other gas components remain gaseous. If the lattice properties of the gases (in the frozen state) are sufficiently different, then molecules or atoms of the other gas components are not regularly included in the lattice of the solid body installed. Some gas molecules or atoms are bound at most by adsorption on the surface of the resulting solid.
- the method has also been used particularly successfully with a xenon-nitrogen and a xenon-krypton-nitrogen gas mixture for the separation of xenon.
- the method can be carried out with very simple means and therefore inexpensively.
- a device for performing the method comprises at least two cooling containers (cold trap,
- Freeze-out section cooled to working temperature can be.
- Each cooling container has a lockable inlet and outlet.
- a pump is connected to each outlet.
- the device further comprises means for being able to alternately supply the gas mixture to one and the other cooling container in such a way that the desired partial pressure is established in the respective container. Continuous operation can be ensured by alternately supplying the gas mixture. If there is a gas mixture in one of the containers or if the gas mixture is passed through this container (flow-through mode), the component to be separated is frozen out in the container and then the container is pumped empty. So only the frozen gas (solid) remains in the container. The solid can then be suitably removed from the corresponding container. This can be done, for example, by heating. The resulting excess pressure can be used directly to fill a gas bottle connected to the container with pressure. A 100% recovery of, for example, xenon from a gas mixture is possible without any problems.
- the sophisticated method can basically be applied to any gas mixture if the specified conditions are met.
- the device exhibits in an advantageous
- Embodiment means, which supply the gas mixture in the container to the cooling surfaces (cooling surfaces). This ensures that the gas mixture always reaches the cooling surfaces where the gas freezes out. The freezing can then be carried out reliably and economically in the flow operation of the gas mixture through the container.
- the device has surface-enlarging cooling plates in the cooling container. The cooling capacity can be increased in this way.
