    Abstract: The present invention is concerned with a process and a plant for the production of sulphuric acid wherein a sulphur dioxide-containing feed gas is converted, at least in part, with oxygen in at least two contact stages of main contacts arranged in series, to generate sulphur trioxide, and wherein generated sulphur trioxide-containing gas is conducted to an absorber and converted therein to sulphuric acid. In order to be able to economically process feed gases of a sulphur dioxide content of between 13 and 66 % by volume to sulphuric acid, using conventional catalysts, it is suggested to withdraw from a contact stage connected upstream of the last main contact stage, a partial stream of the sulphur dioxide- and sulphur trioxide-containing gas, to mix the said partial stream with the feed gas to generate a contact gas of a sulphur dioxide content of more than 13 % by volume, and to return the same to the first contact stage.

    Abstract: A centrifugal pump for hot media, in particular hot water, has at least one opening provided with an axial face seal (5) for a shaft that extends outside the pump housing (1, 2). The sealing space (9) is separated from the pump housing (1, 2) by a spacer section (8) with little shaft clearance. To avoid sealing failures caused by collected gas, the sealing space (9) has means (12, 20, 21) for generating fluid circulation within the sealing space (9), intensively applied on the axial face of the axial face seal (5), means (12, 18, 21) for reducing the fluid circulation away from the axial face seal (5), and a large, flow-abated receiving space for separated gas, capable of being vented. The gaseous components are thus reliably separated from the axial face seal (5), removed from the fluid circulation and collected in the upper part of the sealing space (9), so that they are extracted of the fluid circulation and can be discharged.
