摘要： In the process for reducing the total sulfur content of a high CO.sub.2 -content feed gas stream, the feed gas is first passed to an absorption column. The unabsorbed, high CO.sub.2 -content gas is then routed to a reduction step where it is combined with Claus off-gases and the sulfur compounds are reduced to H.sub.2 S. The treated gas is then passed to a second absorption column and the unabsorbed gas is vented to the atmosphere. The fat solvent from both absorption columns is stripped in a common stripper and the stripped gas is passed to a Claus unit for conversion to elemental sulfur.

摘要： This invention relates to a method for producing a hydrogen stream and a carbon dioxide stream from a mixed gas feedstock containing hydrogen, carbon dioxide, and contaminant sulfur compounds. The method comprises scrubbing the gas feedstock with a carbon dioxide laden solvent in an initial scrubbing zone under conditions such that not more than 70% of the carbonyl sulfide in the feedstock is removed in the initial zone, physically scrubbing the initially scrubbed feedstock with a solvent under conditions sufficient for removing substantially all the carbon dioxide and carbonyl sulfide therefrom to leave a pure hydrogen stream desorbing carbon dioxide and carbonyl sulfide and other gases from the liquid from the second scrubbing zone and then fractionating the resultant carbon dioxide stream containing hydrogen, carbon oxides, etc. to produce said carbon dioxide stream for use in urea synthesis.

摘要： The present invention relates to a method of processing residual gases containing sulfur, hydrogen sulfide, and sulfur oxides and supplied from Claus plants or other surfur-producing installations, wherein the Claus plant is operated along or in connection with an ammonia decomposition plant in which ammonia-containing heated gases are directed through a decomposition zone which is free or filled with heat-resistant filler bodies or with a catalyst material, and the ammonia is decomposed into nitrogen and hydrogen and, thereupon, the gases are cooled and washed. The residual gases containing sulfur, hydrogen sulfide, sulfur oxides and ammonia-containing heated gases are fed to an ammonia decomposition chamber where the ammonia is decomposed into nitrogen and hydrogen and the residual gases react to produce a product gas enriched in hydrogen sulfide, the hydrogen for the reaction being supplied by the decomposition of ammonia. The product gas is further treated and the hydrogen-containing gas suitable for undergrate firing is removed therefrom.

摘要： An anti-pollution system for industrial smoke stacks has a source of live steam feeding steam to a nozzle centered in the upper part of the stacks and several concentrically steam cooling towers of progressively smaller diameter. Each chamber opens into the other and has a drain for conveying water laden with unburned particles and soot to filters at the bottom of the stacks.

摘要： Acidic gases are substantially removed from a normally gaseous mixture by a process comprising contacting the normally gaseous mixture with an amine-solvent liquid absorbent comprising (i) an amine mixture comprised of at least about 50 mol % of a sterically hindered amine and at least about 10 mol % of a tertiary amino alcohol, wherein said sterically hindered amine contains at least one secondary amino group which is part of a ring and is attached to either a secondary or tertiary carbon atom or a primary amino group attached to a tertiary carbon atom, and (ii) a solvent for said amine mixture which is also a physical absorbent for said acidic gases. The liquid absorbent may also include up to about 35 weight percent water. The coaction of the sterically hindered amine and the tertiary amino alcohol in conjunction with the solvent provides an increase in the amount of CO.sub.2 containing acidic gases absorbed compared to the use of the same sterically hindered amines alone and lowers the heat of reaction.
