Definitions
- the present invention relates to a process for recovery of heavy metals and halogens using a series of ion exchange and chelating resins.
- Terephthalic acid is one such carboxylic acid that is used in the production of many different polymers, including polyethylene terephthalate (PET).
- PET polyethylene terephthalate
- Terephthalic Acid is produced by direct oxidation of p-xylene, catalyzed by heavy metals, such as Co and Mn, and a radical initiator, such as bromine.
- the oxidized product is subsequently crystallized and subjected to solid liquid separation, producing i) a solid stream comprising the product, ii) a mother liquor stream to be partially recycled to the oxidation process, and iii) a liquid stream.
- the liquid stream is processed for solvent recovery, and in this solvent recovery operation, the catalysts and radical initiators present in the liquid stream are either lost or only partially recovered by means of low-efficient chemical and/or physical methods. Moreover when low purity feed stocks are used for the production of aromatic carboxylic acids, the liquid stream has to be increased relative to the other streams, increasing the value of the catalysts and initiator lost through the liquid stream.
- the present invention is a process for the removal and recovery of i) at least one heavy metal selected from the group consisting of Co, Mn, and a combination thereof, and ii) bromine, from a liquid stream in a chemical process, the process for the removal and recovery comprising the steps of: a) contacting the liquid stream with a strong base anion exchange resin in halogenide form; b) contacting a discharge stream from step (a) with a chelating cation exchange resin; c) regenerating the anion exchange resin in step a by contacting the anion exchange resin with an anion exchange resin regeneration solution comprising water and acetic acid to form recovered heavy metals and bromine; d) regenerating the chelating cation exchange resin by contacting the chelating cation exchange resin with a regeneration primer comprising HBr and thereafter contacting the chelating cation exchange resin with a regeneration solution comprising water to form recovered heavy metals and bromine; e) purifying the recovered heavy metals and
- Figure 2 is a schematic diagram of another embodiment of a recovery system of the present invention.
- terephthalic acid for example, comprises the oxidation of p-xylene to form terephthalic acid.
- the catalysts used in the liquid phase oxidation and ending up in the liquid stream comprise heavy metals and/or halogens.
- the heavy metals comprise one or more of cobalt, manganese, cerium, zirconium and hafnium; and the halogen comprises bromine.
- Figure 1 shows one embodiment of a recovery system 10 that can be used for the present invention. As shown, recovery system 10 comprises a reservoir 11, a column 13 containing an ion exchange resin, and a bed 17 containing a chelating resin.
- a liquid stream 12 is withdrawn from reservoir 11.
- the configuration of reservoir 11 is not critical to the present invention, and as with most chemical processing systems, the nature of the chemical process will dictate the configuration and materials of construction of the reservoir 11 and other auxiliary equipment.
- the concentration of heavy metals and halogens in the liquid stream 12 is not critical to the present invention, and the present invention is effective with nearly any concentration of heavy metals and/or halogens.
- Typical concentration ranges of heavy metals and halogens in a liquid stream can be, for example, a bromide concentration of between 200 and 1000 parts per million (ppm); a cobalt concentration of between 100 ppm and 800 ppm; and a manganese concentration of between 200 ppm and 1000 ppm.
- the ion exchange resin is a strong base anion exchange resin selected to absorb at least a portion of heavy metals and halogens from the liquid stream.
- the strong base anion exchange resin is a strong base anion exchange resin in the halide form, and more preferably a chlorinated or brominated anion exchange resin.
- the strong base anion exchange functional group is an amine group.
- the strong base anion exchange resin is a strong base quaternary amine anion exchange resin in the bromide form.
- the conversion of a strong base anion exchange resin to the bromide form can be obtained by washing the bed of the resin, in any form, with 10-50 times the resin bed volume (defined herein as the volume of the ion exchange resin bed) of a strong base solution and then with 5- 20 resin bed volume of a solution containing bromide, preferably at a concentration of at least 3 wt % bromide.
- the strong base anion exchange resin can be supported on any matrix.
- the strong base anion exchange resin is supported on a styrene-based matrix, and more preferably a styrene-divinylbenzene matrix.
- the chelating resin in bed 17 is a resin selected to absorb heavy metals and/or halogens, and more particularly, cobalt, manganese, cerium, zirconium, hafnium bromine, from the liquid stream.
- the chelating group of the chelating resin is a carboxylic acid chelating group, more preferably a dicarboxylic acid group.
- the chelating resin is an imido diacetic acid resin.
- the chelating resin can be in any form such as, for example, the sodium or hydrogen form, and more preferably the hydrogen form.
- the chelating resin can be supported on any matrix.
- the chelating resin is supported on a styrene-based matrix, and more preferably a styrene-divinylbenzene matrix.
- the anion exchange resin in column 13 and the chelating resin in bed 17 will become fully loaded with heavy metals and/or halogens and therefore must be regenerated.
- a resin bed is typically sized to last for a specified period of time before regeneration is required, or that the concentration levels of heavy metals and/or halogens in effluent stream 18 will change, signaling a need for regeneration.
- the heavy metals and/or halogens are recovered and optimally may be used in the production process for the aromatic carboxylic acids.

- the regeneration primer comprises an acid such as hydrochloric acid or hydrobromic acid and may also include acetic acid.
- the concentration of hydrobromic acid or hydrochloric acid in the regeneration primer is from 1-20% by weight, more preferably from 2-10% by weight, and even more preferably from 3-6% by weight.
- the concentration of acetic acid in the regeneration primer is from 0 to 98% by weight, more preferably from 10-95% by weight, and even more preferably from 85-90% by weight.
- water can be added to the regeneration primer in a preferred concentration of from 1.5-100% by weight, more preferably from 3-50% by weight, and even more preferably from 4-35% by weight.
- the chelating cation exchange resin regeneration solution comprises water or a combination of water and acetic acid.
- concentration of water in the chelating cation exchange resin regeneration solution is from 30 to 100 weight %, more preferably from 50 to 100 wt %, and even more preferably from 80 to 100 wt%.
- concentration of acetic acid in the chelating cation exchange resin regeneration solution is from 0 to 30%.
- the resulting stream contains the recovered heavy metals and halogens in a ratio of halide to heavy metals of from about 3 to about 10.
- the ratio of Br- : (Co + Mn) is from about 2 to about 10, more preferably from 2 to 8, and even more preferably from 2 to 5.
- the recovery system 20 in Figure 2 comprises reservoir 21 , and chelating resin bed 23.
- the chelating resin is selected such that only the chelating resin is needed to recover the heavy metals and halogens, and an anion exchange resin is not needed. Otherwise, bed 23 operates in the same manner as bed 17 in the embodiment depicted in Figure 1.
- Effluent stream 24 has similar properties to those of effluent stream 18 in the embodiment depicted in Figure 1.

- Feed stream 19 or feed stream 25 can be fed to bed 40 either in series with the strong base anion resin bed and chelating cation exchange resin beds 17/23, or by means of a buffer vessel 30 equipped with a pump.
- Feed stream 19 or feed stream 25 optimally also comprises at least 35% water so as to optimize the efficiency of the purification step and of the operation of the strong base anion exchange resin in the OH- form, 40, as illustrated in Fig. 2.
- stream 41, containing purified heavy metals and halogens may be fed back to the oxidation process.
