The regenerator uses gravitational flow to feed the flash section, eliminating the need for an external flash tank, and charge pump even without vacuum. The internal flash section has a first pressure side, a second pressure side having a lower pressure than the first pressure side during gas flow and a pressure reduction zone disposed therebetween. The pressure drop in the pressure reduction zone is due to liquid flow pressure losses occurring as liquid flows from said first pressure side to said second pressure side. A liquid seal between the first pressure and second pressure sides eliminates the need for a pressure let down valve. Vacuum control is provided by the first pressure side liquid level.Type: GrantFiled: December 15, 1993Date of Patent: July 25, 1995Assignee: Eickmeyer & Associates, Inc.Inventor: I-Meen Chao

Patent number: 5223173Abstract: A method of removing hydrogen sulfide from a sour gaseous stream in a contact zone by contacting the sour gaseous stream with a H.sub.2 S selective absorbent in an aqueous alkaline solution containing a polyvalent metal chelate at a pH of about 7 to about 10 wherein the polyvalent metal chelate is in one embodiment of the invention in the reduced or lower valence state in a contact zone and is oxidized to the oxidized or higher valence state in an oxidation zone so as to convert absorbed hydrogen sulfide, hydrosulfide and/or sulfide salts present in the contact zone to sulfur. In a second embodiment, the aqueous alkaline solution and H.sub.2 S selective absorbent in contact with the gaseous stream is a mixture containing a higher valence polyvalent metal chelate together with a lower valence polyvalent metal chelate.Type: GrantFiled: September 25, 1992Date of Patent: June 29, 1993Assignee: The Dow Chemical CompanyInventor: Gaines C.

Patent number: 5053371Abstract: A semi-continuous process for combusting coke from catalyst particles in a fixed bed is improved by injecting combustion air for the regeneration section to the three places, upper air to the burn zone, middle air to the chlorination zone and lower air to the burn zone. By this method combustion gas is added the halogenation gas loop which circulates chlorination gas around the chlorination zone in substantially closed system. Any gas that leaves the chlorination zone flows into the burn zone from the chlorination zone. Thus, passing additional air to the chlorination zone increases the oxygen concentration of the chloriation gas to that additional oxygen-containing chlorination gas and chlorination gas with a higher oxygen concentration passes into the burn zone from the chlorination zone. This method adds air for coke combustion and improves platinum dispersion in the halogenation zone.Type: GrantFiled: November 2, 1990Date of Patent: October 1, 1991Assignee: UOPInventor: Robert R. Williamson

Patent number: 4925644Abstract: A process for the simultaneous partial oxidation and desulfurization of sulfur and silicate-containing solid carbonaceous fuel for the production of a gas stream comprising gaseous mixtures of H.sub.2 and CO and containing less than about 0.05 volume % of H.sub.2 S and COS, and entrained fly-ash, calcium sulfide, and particulate carbon. In the process, the solid carbonaceous fuel and a calcium-containing compound are entrained in a gaseous medium and are reacted by partial oxidation in the reaction zone of a free-flow unobstructed gas generator with a controlled amount of free-oxygen containing gas and with or without a temperature moderator so that an equilibrium oxygen concentration is provided in the gas phase in the reaction zone having a partial pressure which is less than about 10.sup.-12 atmosphere. The total moles of calcium in the reaction zone is at least equal to about 1.0 times the moles of sulfur in the solid carbonaceous fuel.Type: GrantFiled: November 28, 1988Date of Patent: May 15, 1990Assignee: Texaco Inc.Inventors: Mitri S.

Patent number: 4889700Abstract: Method and devices for the selective removal of H.sub.2 S from an H.sub.2 S-containing gas by contacting the gas in an absorption column with an H.sub.2 S-selective absorbent liquid and transferring the H.sub.2 S-charged absorbent liquid to the upper part of a second column. The charged absorbent liquid then travels to a regeneration zone at the bottom of the column, where it is heated to a temperature at which the absorbent liquid is vaporized and the H.sub.2 S is released.The regeneration zone temperature causes the absorbent liquid vapor to strip the H.sub.2 S back to the upper part of the column where it forms an equilibrium with the H.sub.2 S-charged absorbent liquid at a temperature not more than 30.degree. C. higher than the injection temperature of the absorbent liquid in the absorption column, which equilibrium temperature is maintained by the temperature in the regeneration zone. The H.sub.2 S-enriched vapor formed at the equilibrium point is then tapped.Type: GrantFiled: June 3, 1987Date of Patent: December 26, 1989Assignee: Societe Nationale Elf Aquitaine (Production)Inventors: Jean Elgue, Olivier Oliveau, Jean-Louis Peytavy

Patent number: 4844876Abstract: Method for the selective removal of H.sub.2 S from a H.sub.2 S-containing gas by operating in a single column (1) comprising an upper absorption zone (11) and a lower regeneration zone (12) separated by a medial enrichment zone (17). A selective absorbing and regeneratable liquid capable of absorbing H.sub.2 S is introduced at the upper portion of the column and flows successively into the zones (11) and (17) and finally into (12). The absorbing liquid meets the gas to be treated, which is injected through a conduit (9), in the zone (11) while the regenerated absorbing liquid is tapped at the bottom (4) of the column and brought back through a conduit (5) into said zone (11). At the head (2) of the column, a gas having a reduced content of H.sub.2 S is discharged and by means of a system (18) provided in the zone (17) an acid gas fraction rich in H.sub.2 S is tapped.
