20080253957 | Process and Plant for Producing Sulfuric Acid - There are described a process and a plant for producing sulfuric acid by catalytic oxidation of SO | 10-16-2008 |
20090068088 | PROCESS AND APPARATUS FOR THE COMBUSTION OF SULFUR - A process for a combustion of sulfur with an oxygen-containing gas to produce sulfur dioxide. The process includes introducing the sulfur and the oxygen-containing gas to a furnace. The sulfur is evaporated and subsequently a portion of the sulfur is oxidized to sulfur dioxide under sub-stoichiometric conditions in a first portion of the furnace. The sulfur dioxide formed in the first furnace portion is introduced together with any unoxidized sulfur to a second portion of the furnace which is disposed adjacent to the first furnace portion. The sulfur dioxide and unoxidized sulfur are subjected to post-combustion with the oxygen-containing gas in an inlet of a downstream waste heat boiler. | 03-12-2009 |
20090269272 | PROCESS AND PLANT FOR THE PRODUCTION OF SULPHURIC ACID - The invention relates to a process and plant for producing sulphuric acid by catalytic oxidation of SO | 10-29-2009 |
20100209320 | SUPPORT RING FOR ACCOMMODATING A PLATE-LIKE ELEMENT IN A VESSEL - A support ring for accommodating a plate-like element in a vessel includes a bracket disposed on a wall of the vessel and configured to support the plate-like element, the bracket having an upper supporting surface inclined downward relative to horizontal. | 08-19-2010 |
20100236636 | FLUID DISTRIBUTION SYSTEM - A system for distributing a fluid via a packing disposed in a container, the packing configured to have the fluid trickle from a top to a bottom thereof, includes at least one distributor member including a pressure conduit having at least one nozzle configured to discharge the fluid therethrough and a distributor channel adjoining the distributor member. A width of the distributor channel does not substantially exceed a diameter of the distributor member. The distributor channel defines at least one outlet slot disposed at a lower end of the distributor channel. The at least one outlet slot has a specified width and is configured to discharge the fluid from the distributor channel to the packing via a guide member. The distributor channel is configured to receive the fluid discharged from the at least one nozzle so as to provide a specified level of the fluid in the distributor channel. The distributor channel forms a ventable chamber above the specified fluid level. The ventable chamber is configured to maintain a pressure corresponding to a pressure in the container in which the packing is disposed. | 09-23-2010 |
20120308473 | METHOD AND APPARATUS FOR ADJUSTING THE CONCENTRATION OF ACIDS OR LYES - A method for adjusting a concentration of an acid or lye includes charging a medium for adjusting the concentration of the acid or lye into a supply conduit of the acid or lye so as to provide a combined stream. The combined stream is supplied through an inlet to a mixing chamber such that the combined stream is deflected upon entering the mixing chamber. The combined stream is mixed in the mixing chamber. The combined stream is discharged through an outlet of the mixing chamber such that the combined stream is again deflected upon being discharged from the mixing chamber. | 12-06-2012 |
20130000869 | PROCESS AND PLANT FOR COOLING SULFURIC ACID - A process for cooling an acid that is withdrawn from an absorption apparatus of a sulfuric acid plant includes pumping the acid to be cooled from an acid pump tank and supplying the acid to a shell space of a heat exchanger. Water is supplied as a heat transport medium to heat transfer elements disposed in the shell space so as to at least partially convert, by heat transfer from the acid, the water to steam. The acid which was cooled in the heat exchanger is supplied back to the absorption apparatus. The water is separated from the steam in a steam drum. The separated water is recirculated to the heat exchanger using a pump. | 01-03-2013 |
20140004034 | PROCESS FOR THE COMBUSTION OF A LIQUID | 01-02-2014 |
20140182816 | GAS/GAS HEAT EXCHANGER - A heat exchanger for use in a contact group of a sulfuric acid plant includes a chamber in which a tube bundle is arranged on a circular ring. A gas space is formed between the tube bundle and a chamber casing surrounding the tube bundle. A gas supply opening is provided in the chamber casing and is configured to introduce a gas into the gas space substantially radially to the tube bundle. A gas outlet opening adjoins an interior space enclosed by the tube bundle in a substantially axial direction. A center of the tube bundle is offset with respect to a center of the chamber casing in a direction opposite to the gas supply opening. | 07-03-2014 |
20140239520 | PACKED TOWER - A packed tower for the absorption of water or SO | 08-28-2014 |
