Definitions
- the invention pertains to the use of an adsorbent for the removal of liquid, gaseous and/or dissolved constituents from a process stream.
- Such a use is generally known and widely employed in chemical engineering.
- One well-known example is the use of a column filled with activated carbon for the removal of, say, aromatic and/or chlorinated hydrocarbons from a process stream. Once the activated carbon in the column has become saturated, it is generally replaced by fresh activated carbon, while the saturated carbon is reactivated. Meanwhile it has been found that several synthetic adsorbents can be regenerated a number of times with, say, steam.
- a major drawback to the known process is that it is susceptible to certain inorganic contaminants which are commonly found in very minute concentration, in, say, groundwater to be treated, such as compounds of iron, manganese, calcium, and magnesium which in themselves are not harmful and so do not need to be removed, yet which nevertheless, in the course of time, may lead to fouling of the adsorbent because a substantial part of its surface area will be covered with said contaminants.
- particles having adsorbent properties instead of particles having adsorbent properties, particles having extracting properties be used.
- the extracting particles having a particle size in the range of 0.1 to 10 mm have pores with a diameter of 0.01 to 50 ⁇ m with an extraction liquid immobilised therein.
- the invention now provides for the use of an adsorbent for the removal of liquid, gaseous and/or dissolved constituents from a process stream which obviates wholly or for the most part the problems which occur when using the known adsorbents.
- the invention consists in that when employing an adsorbent use is made of a porous material, or a material incorporated into a porous material, at least 30 vol. % of the pores of which is filled with an extraction liquid and where the affinity between the adsorbent and the constituents to be removed exceeds the affinity between said constituents and the extraction liquid.
- Extraction liquids are used to extract dissolved constituents or to absorb gaseous constituents.
- Liquids eligible for use as extraction liquid are known to the skilled person. In the case of liquid/liquid-extraction these generally are liquids with minimal solubility in the medium to be extracted. As a rule, the solubility of these liquids in the medium to be extracted is not more than 100 g per 1,000 ml.
- the material having the different composition generally will be a polymeric matrix of the same composition as described in WO 94/03249. In that case preference is given to a porous material where the weight percentage of adsorbent calculated on the overall solids content is at least 2.5 wt. %.
- a large number of adsorbents are eligible for use according to the invention.
- zeolites such as molecular sieves
- silica gels porous alumina including the activated types
- clay particles including the exfoliated types.
- adsorbent When the adsorbent is incorporated into a porous material, preference is given to a material obtained by dissolving a polymer in one or more liquid and miscible compounds at a temperature above the upper critical phase separation temperature Tc in the presence of 2.5 to 80 wt. %, calculated on the overall solids content, of a material with adsorbent properties which is solid at said temperature, followed by a lowering of the temperature and the forming of a fibre, film, granulate or powder from the polymer filled with the liquid compounds, optionally followed by the removal of at least part of the liquid therefrom and by refilling or filling up with an extraction liquid to at least 30% of the pore volume.
- the extraction liquid which is suitable for use according to the invention is a liquid which has the highest possible affinity for the organic constituents to be extracted.
- this liquid should be virtually insoluble in the aqueous solution to be treated and should be immobilised in the porous material in such a way that it is unable to flow from the pores.
- favourable results have been attained using a liquid in the form of a glycerol ester of one or more, preferably unsaturated fatty acids.
- the immobilised liquid is an oil, such as palm oil, olive oil, peanut oil, paraffin oil, fish oil such as herring oil, linseed oil, and especially soybean oil and/or castor oil.
- oil such as palm oil, olive oil, peanut oil, paraffin oil, fish oil such as herring oil, linseed oil, and especially soybean oil and/or castor oil.
- paraffin oil and a dialkyl phthalate with an alkyl group having 8 to 16 carbon atoms are especially olive oil, peanut oil, paraffin oil, fish oil such as herring oil, linseed oil, and especially soybean oil and/or castor oil.
- Examples of polymers into which the adsorbent can be incorporated are: low-pressure polyethene, high-pressure polyethene, polypropylene, polystyrene, acrylonitrile-butadiene-styrene terpolymers, styrene-acrylonitrile copolymers, styrene-butadiene copolymers, poly(4-methyl-pentene-1), and polybutene.
- the thus combined porous material can be used in the form of a fibre, film, granulate or powder, with preference being given to use in the form of a granulate or powder having an average particle diameter of 0.1 to 10 mm.
- the material is generally introduced into a column as a packing material.
- the process stream supply is halted and the process stream is passed to a column connected in parallel.
- the material saturated with the constituent to be extracted can be regenerated.
- the principal parameters determining the effectiveness of a column filled with particles with a liquid extraction medium immobilised therein are the equilibrium constant of the distribution of the substance to be extracted over the continuous phase to be extracted and the immobilised phase and the mass transfer rate.
- Diisodecyl phthalate was selected as the oil, and the selected adsorbents were: Ambersorb® 563, black spherical beads with a specific surface area of 550 m 2 /g (ex Rohm and Haas Co.), activated carbon SA Super® (ex Norit), and XAD-4® (ex Rohm and Haas), a copolymer of styrene and divinyl benzene
- Table 1 TABLE 1 type with oil- wt. % of wt.
- Types P6 and P7 were prepared in an analogous manner, with the proviso that P6 contained 15 wt. % of activated carbon and P7 contained 15 wt. % of Ambersorb 563®.
- composition of types P4 through P7 is listed Table 2.
- Table 2 type with oil- filled matrix wt. % wt. % diisodecyl and, optionally, adsorbent/- phthalate/castor adsorbent adsorbent matrix matrix oil (80/20)
- P4 none polypropylene 0/30 70
- P5 activated carbon polypropylene
- P6 activated carbon polypropylene 15/30 55
- the example below shows how the adsorption capacity of adsorbents filled with extraction liquid (oil) for a particular type of contaminant can be determined.
- the measurements were performed with methylene chloride (DCM) as contaminant in water at concentrations ranging from 0.1 to about 5,000 ppm and are the result of a number of shaking tests in which a certain quantity of adsorbent was added to a measured quantity of water with a known quantity of methylene chloride dissolved therein.
- the mixture of solution and adsorbent in each case was stirred for 24 hours, after which the remaining concentration of methylene chloride was again determined. From the difference in concentration the quantity of methylene chloride adsorbed by the adsorbent could be calculated.
- the capacity of the particles as a function of the equilibrium concentration could be determined. The result of the measurements is shown in FIG. 1.
- FIG. 2 clearly shows that under virtually comparable conditions breakthrough occurs much more quickly when particles without adsorbent (P4) are used than when use is made of particles containing an adsorbent as well as an extracting agent (P7).
- the adsorption capacity of the adsorbent in the particle is determined by dividing the remaining quantity of DCM by the quantity of adsorbent that is present. The thus determined adsorption capacity of the adsorbent in the particle is compared with the capacity of pure adsorbent.
- FIG. 3 shows the thus determined capacity for activated carbon covered with extracting agent as determined in the particles P2, P5, and P6, as well as the capacity of pure activated carbon for comparative purposes.
- FIG. 4 shows the capacity of pure Ambersorb® 563 and of Ambersorb® 563 as present in particle P7.
