PCT/US2014/015544STEAG ENERGY SERVICES GMBHMARRINO, Birgit
Methods of removing iron from a catalytic converter having an accumulation of one or more iron compounds and regenerating a catalytic converter are provided. A catalytic converter having an accumulation of one or more iron compounds embedded or deposited thereon can be treated with a substantially aqueous alkaline solution in which the substantially aqueous alkaline solution includes an antioxidant.

2. WOWO/2014/140108 - PROCESS FOR CAPTURING CO2 FROM A CO2-CONTAINING GAS STREAM USING A THERMORESPONSIVE COPOLYMER18.09.2014
B01D 53/14
PCT/EP2014/054854CARBONORO B.V.CUSTERS, Johannes Petrus Aldegonda
The present invention pertains to a process for capturing CO2 from a CO2- containing gas stream, comprising the steps of contacting a CO2-containing gas stream with a CO2-absorbing agent in an absorption step in a vessel with a maximum temperature T1 resulting in absorption of CO2, the CO2-absorbing agent comprising a polymer dissolved in an aqueous medium, the polymer being a thermoresponsive copolymer comprising amine monomer distributed through the copolymer, and subjecting the CO2-containing absorbing agent to a desorption step in a vessel with a maximum temperature T2, resulting in the release of CO2, wherein T1 is below the LCST of the thermoresponsive polymer at maximum CO2 loading, and T2 is above the LCST of the thermoresponsive polymer at minimum CO2 loading, wherein the CO2 absorbing agent additionally comprises amine component dissolved in the aqueous medium. The use of the specific polymer in the present invention which is dissolved in an aqueous medium at T1, and wherein amine monomer is distributed through the copolymer in combination with an amine component shows an improved net CO2 sorption and a high absorption speed, which allows the use of a relatively small absorption reactor.

Provided is a catalyst composition having an aluminosilicate molecular sieve having an AEI structure and a mole ratio of silica-to-alumina of about 20 to about 30 loaded with about 1 to about 5 weight percent of a promoter metal, based on the total weight of the molecular sieve material. Also provided are method, articles, and systems utilizing the catalyst composition.

4. WOWO/2014/144954 - CLEANING STACK GAS18.09.2014
B01D 53/83
PCT/US2014/029570THREE D STACK, LLCDAVIDSON, James Gary
A method and apparatus for cleaning and recycling stack gas from coal-fired power plants, from natural or propane burning heating plants, or from cement kilns by using renewable catalysts of zeolite to separate pollutants into recyclable and reusable materials. The method reduces from the stack gas carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx), sulfur oxide (SOx) as well as halogens such as chloride and fluorides and trace metals particularly, mercury, lead, and zinc. Bauxite compounds can also be separately collected if desired. The method and apparatus also result in production of fertilizer products by purging with gaseous or liquid nitrogen the zeolite beds through which the stack gas flows. The oxygen split in the beds may be recycled to the burners in the plant.

5. WOWO/2014/142668 - COS AND CS2 ABATEMENT METHOD18.09.2014
B01D 53/14
PCT/NL2014/050157STAMICARBON B.V. ACTING UNDER THE NAME OF MT INNOVATION CENTERCOLOZZI, Michele
Disclosed is method for removing carbonyl sulphide and/or carbon disulphide from a sour gas stream. The method comprises subjecting the gas stream to simultaneous contact with an absorption liquid, such as an aqueous amine solution, and with a catalyst suitable for hydrolyzing carbonyl sulphide and/or carbon disulphide. To this end, the invention also provides a reactor system wherein both an absorption liquid and a catalyst are present. In a preferred embodiment, the catalyst is a heterogeneous catalyst present on or in an absorption column, either coated on the trays of a column with trays, or contained in the packing of a packed column.

6. WOWO/2014/144618 - REGENERATIVE RECOVERY OF CONTAMINANTS FROM EFFLUENT GASES18.09.2014
B01D 53/50
PCT/US2014/029103MECS, INC.VERA-CASTAÑEDA, Ernesto
A contaminant gas is removed from a feed gas in two absorption and stripping circuits operated in tandem. The gas is first passed through a rich gas absorber producing a rich absorption liquor from which contaminant gas is stripped in a rich liquor stripper. A lean gas exiting the rich gas absorber is passed through a lean gas absorber, producing a lean absorption liquor from which contaminant gas is stripper in a lean liquor stripper. Regenerated absorption media exiting the respective strippers are recirculated to the respective absorbers.

7. WOWO/2014/138908 - PROCESSES FOR THE REJUVENATION OF AN AMINE ACID GAS ABSORBENT USED IN AN ACID GAS RECOVERY UNIT18.09.2014
B01D 53/96
PCT/CA2014/000239CANSOLV TECHNOLOGIES INC.INFANTINO, Mélina
A process for the recovery of an amine acid gas absorbent used in an acid gas recovery unit, comprising obtaining an amine-containing waste stream from a heat stable salt (HSS) removal unit wherein a HSS containing amine acid gas absorbent stream is contacted with a base and subjected to a first phase separation step whereby a light regenerated amine absorbent stream and the amine-containing waste stream are produced; contacting the amine-containing waste stream with an organic solvent and obtaining an amine rich organic solvent stream and an amine reduced waste stream; and contacting the amine rich organic solvent stream with an acid and obtaining a protonated amine stream and an amine reduced organic solvent stream.

C25B 9/08
PCT/SG2014/000124WISEWATER PTE. LTDLIU, Haobing
Some embodiments described herein generally relate to apparatus and methods for performing polarized electrodialysis, which may be used for desalination, purification and concentration. Such apparatus may include, for example, a pair of electrodes, a plurality of ion exchange membranes disposed between the pair of electrodes and a reservoir between each of the electrodes and the ion exchange membranes. The ion exchange membranes may include cation exchange membranes alternating with anion exchange membranes. A voltage may be applied between the pair of electrodes to generate concentration polarization wherein concentration of ions near the surface of one of at least one of the cation and anion exchange membranes is lower than a concentration of ions in the sample solution. The solution with lower ion concentration may be collected to form a desalinated stream by the apparatus. The apparatus and methods may also be able to remove or concentrate less mobile, weakly charged or bigger matters which cannot be purified by conventional electrodialysis.
