摘要： A vessel for producing SO3 from SO2-containing gas includes a plate-like element and a bracket disposed on a wall of the vessel. The bracket is configured to support the plate-like element by a supporting surface. The supporting surface is an upper supporting surface curved downward away from the plate-like element in an unloaded state of the vessel or a lower supporting surface curved upward away from the plate-like element in the unloaded state of the vessel.

摘要： A process for cooling an acid that is withdrawn from an absorption apparatus of a sulfuric acid plant includes pumping the acid to be cooled from an acid pump tank and supplying the acid to a shell space of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.

摘要： 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.

摘要： A process for the combustion of a liquid in a combustion chamber includes atomizing liquid sulfur using a rotary atomizer and introducing the liquid sulfur into the combustion chamber. The liquid sulfur is charged onto an inside of a cup. The cup is rotated so as to form a liquid film on the inside of the cup and so that parts of the liquid film are radially flung off from an edge of the cup edge into the combustion chamber. The rotational speed of the cup is varied so as to control a thickness of the liquid film in the cup to between 200 and 1000 μm. The liquid sulfur is evaporated and subsequently burnt in the combustion chamber.

摘要： 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.

摘要： A packed tower for the absorption of water or SO3 in sulfuric acid includes a jacket and a domed grid disposed within the jacket. The domed grid is held on an L-shaped ring such that a gap is formed between an outside diameter of the domed grid and the jacket. A bed of packings is held on the domed grid through which the sulfuric acid charged from above trickles. A gas supply tube is disposed in a lower region of the tower. A gas outlet is disposed above the bed. An acid outlet is disposed in the lower region of the tower.
