摘要： A system for distributing a fluid, for instance organic solvents, water, aqueous salt solution, lyes or acids, via a random packing (PA) or some other structured packing, in which the fluid trickles from the top to the bottom, preferably in countercurrent or cocurrent flow with a gas containing e.g. SO3 or noxious substances, comprising at least one distributor element (1 ), from which the fluid is introduced via openings into a distributor channel (2) such that below the openings a specified fluid level (FP) is obtained in the distributor channel (2), wherein fluid is discharged from the distributor channel (2) via at least one outlet gap (3) of specified width at the lower end (4) of the distributor channel (2) to the packing (PA) by means of a guide member (5), wherein the distributor member (1 ) constitutes a pressure conduit, from which the fluid is discharged via nozzles (6) into a basically closed, but ventable chamber (7) of the distributor channel (2) formed above the fluid level (FP), in which a pressure corresponding to the pressure existing in the container accommodating the packing (PA) can be maintained.

摘要： A process for the condensation of sulfur trioxide from hot starting gases comprising the following steps: a) cooling the starting gas to a temperature of 40 to 45O0C in at least one heat exchanger (3) (4), in which a gas is used as cooling medium, b) introducing the cooled starting gas into a condensation device (5), c) condensing the sulfur trioxide in the condensation device (5), in which a liquid chemically inert to sulfur trioxide is used as cooling medium, and d) withdrawing the condensed, liquid sulfur trioxide from the condensation device (5). A plant for carrying out the process comprising: a first and a second heat exchanger (3) (4) comprising supply and discharge conduits for coolant and starting gas, and a condensation device (5), in which a liquid chemically inert to sulfur trioxide is provided as cooling medium.

摘要： During the combustion of sulfur with air for producing sulfur dioxide, sulfur is burnt in a first portion of the combustion furnace under substoichiometric conditions. The sulfur dioxide formed in the first portion and unburnt sulfur are supplied to a second portion of the furnace adjoining the first portion, in that they are subjected to post-combustion with air. This provides for the production of sulfur-dioxide- containing gas free from nitrogen oxide.
