Definitions
- the invention relates to a method for separating condensable substances from gases or gas mixtures, in particular for separating water from air, using porous materials.
- the object of the present invention is to provide a method for
- the process according to the invention is characterized in that suitable materials or substances are used for the capillary condensation which are particularly favorable for the climatic conditions (operating conditions) at the place of use and enable optimal regeneration yields.
- the special feature of the invention is therefore the selection of the suitable material and its internal structure. Instead of the material used so far and essentially oriented towards adsorption, one is selected with which the so-called capillary condensation enables high volume-specific yields through shorter regeneration cycles.
- the capillary structure of the adsorbent is also coordinated with the adsorbate and with the medium (gas) containing the adsorbate or the external conditions.
- the condensation takes place by capillary pressure based on the existing pore radii, whereby the inner capillary structure to be selected has a volume-specific e.g. Water retention and high yields through short-term regeneration (more than 6 per night) results.
- the binding forces to be overcome for the regeneration of the moisture are then considerably lower than in the case of binding due to previous adsorption or undefined
- ERS ⁇ ZBL ⁇ TT (RULE 26) Capillary condensation.
- the extraction of drinking water from the air can be carried out effectively with the new process and is no longer limited to a single regeneration per adsorption body and day. Other applications are also conceivable, such as the recovery of solvents.
- a hydrophobized material is preferably used. This limits the absorption of liquid by adsorption.
- the material can be regenerated by a combination of regenerative energy sources, for example using solar energy, photovoltaic energy, wind energy and / or an additional storage of these energies with corresponding accumulators.
- the material has micropores and / or mesopores in the size range from 4 to 20 angstroms or 20 to 500 angstroms.
- a material with different pore sizes that are optimally adapted to the place of use is advantageously used. In this way, different levels of moisture in the air can be covered and optimal conditions for regeneration can be set.
- a stream of cool, moist air from the atmosphere e.g. Desert areas preferably at night, passed through a pack of microporous material to average the water vapor contained in the air to the microporous material
- REPLACEMENT B ⁇ (RULE 26) Deliver capillary condensation.
- RULE 26 Deliver capillary condensation.
- Adsorber resins molecular sieves
- the substances mentioned can be used if they have a pore and pore radius distribution suitable for capillary condensation. In particular, micropores and / or mesopores of a certain size are present. To adapt to the climatic conditions in the Sahel region, about 60% of the material has pore radii of 40 to 200 angstroms. Otherwise, the pore radii are outside these limits, but preferably between 4 to 500 angstroms.
- the material is heated to evaporate the substance.
- an air flow guided in a closed circuit is heated by an air heater by previously stored solar energy or by wind energy or directly generated wind or solar energy and passed through the packing filled with material in order to feed the energy portion back to the microporous material, which is at the capillary condensation has been released.
- the water vapor bound in the material escapes and is taken up by the circulating air flow.
- the air stream thus loaded with water vapor is passed through a condenser contained in the circuit, the water vapor contained in the air condensing out.
- the material for evaporating the substance is heated electrically.
- an electrically conductive material for example electrically conductive ceramic as an adsorbent.
- the material can be connected to a voltage source, which is fed from stored solar power.
- the current flow in the material can also be generated by induction.
- the use of a good heat-conducting material is advantageous.
- the substance in the material is heated by microwaves and caused to evaporate.
- the use of a non-metallic material is then advantageous.
- adsorption and desorption of the substance are preferably cyclical, e.g. performed at night. It is also possible and advantageous to carry out more than 6 cycles at night, with only a partial section of the total desorption and desorption being realized. Depending on the internal structure, this section contains the largest volume-specific proportion of water. In this way, more than 600 liters of water per t of adsorbent can be obtained per night. The freshly extracted substance (drinking water) is available at the beginning of the day.
- the extraction of water from a suitable material requires significantly less mass of adsorbent than is the case with the current method of desorbing water vapor from ordinary zeolites (suitable for adsorption) or silica gels.
- the material has a pore radius distribution that is defined and thus optimized for special use (temperature, air humidity and air pressure on site).
- the material is in particular in the form of granules, pellets or shaped bodies of a defined structure. Other shapes are possible.
