摘要： A method and system for the selective removal of CO
2 and/or H
2 S from a gaseous stream containing one or more acid gases. In particular, a system and method for separating CO
2 and/or H
2 S from a gas mixture containing an acid gas using an absorbent solution and one or more ejector venturi nozzles in flow communication with one or more absorbent contactors. The method involves contacting a gas mixture containing at least one acid gas with the absorbent solution under conditions sufficient to cause absorption of at least a portion of said acid gas. The absorbent contactors operate in co-current flow and are arranged in a counter-current configuration to increase the driving force for mass transfer. Monoliths can be used that operate in a Taylor flow or slug flow regime. The absorbent solution is treated under conditions sufficient to cause desorption of at least a portion of the acid gas.-

摘要： A process for the removal of hydrogen sulfide from a gas stream in which the gas stream is first passed through a Claus unit operating at a sub-stoichiometric ratio (H2S:SO2) of greater than 2:1 to produce a tail gas stream comprising less than 2000 vppm SO2. This tail gas stream is then treated to increase the sulfur recovery to at least 99.5% by first directly cooling the tail gas stream by contact with water as a coolant, followed by contacting the gas stream with a circulating stream of a dilute, absorbent solution of a severely sterically hindered secondary aminoether alcohol to further cool the gas stream, and then removing the H2S from the stream using a stronger absorbent solution of a severely sterically hindered secondary aminoether alcohol.

摘要： Systems and methods are provided for performing CO2 sorption and regeneration processes that can take advantage of phase changes between solutions of amine-CO2 reaction products and precipitate slurries, where the slurry particles can include solid precipitates formed based on the amine-CO2 reaction products. An amine solution can be used to capture CO2 from a gas phase stream. During this initial capture process, the amine-CO2 reaction product can remain in solution. The solution containing the amine-CO2 reaction product can then be exposed to a set of conditions which result in precipitation of a portion of the amine-CO2 reaction product to form a slurry. The precipitate slurry can be passed into one or more release stages where the conditions for the slurry are altered to allow for release of the CO2.

摘要： A process for increasing the selectivity of an alkanolamine absorption process for selectively removing hydrogen sulfide (H
2 S) from a gas mixture which also contains carbon dioxide (C0
2 ) and possibly other acidic gases such as COS, HCN, CS
2 and sulfur derivatives of C
1 to C
4 hydrocarbons, comprises contacting the gas mixture with a liquid absorbent which is a severely sterically hindered capped alkanolamine or more basic sterically hindered secondary and tertiary amine. The improvement in selectivity is achieved at the high(er) pressures, typically least about 10 bara at conditions nearing the H
2 S/C0
2 equilibrium at which C0
2 begins to displace absorbed hydrosulfide species from the absorbent solution.-

摘要： A process for the selective separation of hydrogen sulfide from gas mixtures containing carbon dioxide as well as other acidic gases uses severely sterically hindered amino alcohol absorbents based on amino alcohols and ethers containing secondary nitrogen atoms hindered by an alpha tertiary carbon atom. Preferred absorbents include 2-(N-methylamino)-2-methylpropan-1-ol, (2-(N-ethylamino))-2-methylpropan-1-ol, (2-(N-isopropylamino)-2-methylpropan-1-ol, SBAE (2-(N-sec-butylamino)-2-methylpropan-1-ol) and (2-(N-t-butylamino)-2-methylpropan-1-ol.

摘要： A process for absorbing H
2 S and CO
2 from a gas mixture containing both these gases comprises contacting the gas mixture with an absorbent combination of (i) primary absorbent component comprising a severely sterically hindered tertiary etheramine triethylene glycol alcohol or derivative of such an alcohol and (ii) secondary absorbent component for acidic gases comprising a liquid amine such as methyldiethylamine (MDEA), monoethanolamine (MEA), 2-amino-2-methyl-l-propanol (AMP), piperazine (PZ), diethanolamine (DEA), triethanolamine (TEA), diglycolamine (aminoethoxyethanol, DGA) and diisopropylamine (DIPA) another etheramine alcohol or diamine. By using the combination of amine absorbents, the overall selectivity of CO
2 pickup can be maintained while retaining good H
2 S sorption selectivity; the selectivity of the combination for H
2 S and C02 may be controlled over a range of gas loadings in the absorbent.
