Filed:

Mar 27, 2001

Appl. No.:

09/819948

Inventors:

Michael F. Ray - Houston TX 77005
Marcus Rajchel - Arvada CO 80005

International Classification:

C01C 308

US Classification:

423371, 210681, 210683, 423379

Abstract:

Methods for producing cyanide salts using a metathesis process using ion exchange to facilitate a double-decomposition reaction where components of a cyanide-containing compound are exchanged to produce a cyanide salt product are provided. In one embodiment of the invention, HCN may be converted to an alkali salt using a base. The alkali cyanide salt undergoes ion-exchange to yield the desired cyanide salt product. In another embodiment of the invention, hydrogen cyanide is directly converted to cyanide salts in an ion exchange bed without first being converted to a basic salt.

Abstract:

Processes for selectively removing sulfur-containing compounds from a gas are described herein. The processes generally include contacting a first gas including carbon dioxide and hydrogen sulfide with a scrub solution including ammonium bisulfite and ammonium sulfite in a first contact zone to produce a first contact zone effluent liquid including ammonium thiosulfate and a first contact zone overhead gas including carbon dioxide.

Abstract:

Processes for selectively removing sulfur-containing compounds from a gas are described herein. The processes generally include contacting a first gas including carbon dioxide and hydrogen sulfide with a scrub solution including ammonium bisulfite and ammonium sulfite in a first contact zone to produce a first contact zone effluent liquid including ammonium thiosulfate and a first contact zone overhead gas in which the concentration of hydrogen sulfide is substantially reduced.

US Classification:

423514, 423 32, 423388

Abstract:

Process for the production of ammonium thiosulfate from gas streams comprising ammonia and hydrogen sulfide. One embodiment of the invention provides absorbing SOinto a solution of ammonium sulfite and then contacting gaseous feed streams with portions of the resulting solution in a plurality of contact zones where portions of ammonium sulfite in the liquid streams are converted to ammonium thiosulfate upon contact with the gaseous feed streams.

International Classification:

C07C 2/58

US Classification:

585731000

Abstract:

A method is provided for reducing the water content of a sulfuric acid catalyst in a sulfuric acid-catalyzed process carried out in a reactor comprising: (a) withdrawing a portion of catalyst from the acid settler, forming a withdrawn catalyst stream; (b) continuously adding an SO-containing substance to the withdrawn catalyst stream at a desired rate, forming a fortified catalyst, while maintaining the temperature of the fortified catalyst stream below about 60 F.; (c) returning the fortified catalyst to the reactor; whereby the water concentration in the fortified catalyst is maintained at 1.5 to 4 weight percent of the catalyst. A method is also provided for drying paraffinic feed or recycle hydrocarbon streams in a reactor system comprising contacting the feed or recycle hydrocarbon streams with spent sulfuric acid, whereby the feed or recycle streams are dried and whereby a portion of the sulfuric acid esters in the spent acid are converted to sulfuric acid and alkylate. The alkylate produced is extracted into the hydrocarbon phase and returns to the reactor system.

US Classification:

703 10

Abstract:

A hierarchical modeling tool or process is provided that represents the fill range of behavior of a hydrocarbon system, accurately including uncertainties and potential events affecting the system. The potential events may include actions taken and information learned. The hierarchical modeling tool may be embedded within a decision support system or used in a stand-alone fashion. Disclosed aspects may link from accurate (high-detail) physics models to an accurate uncertainty representation, and then reduce the accurate uncertainty representation to a high-speed representation of both the physics model and the uncertainty that can be used in an optimizer.
