    摘要： The invention relates to a condenser, having a process gas side and a heat transfer medium side said condenser being configured for feeding a hot process gas containing a condensable component to an inlet of the condensing side, and being further configured for withdrawing a cooled process gas from an outlet of the condensing side, and being even further configured for withdrawing a condensate in a position proximate to one end of the condenser, and said condenser having the process gas side divided in a process gas cooling zone configured for having a cool heat transfer medium inlet and a heated heat transfer medium outlet, and a process gas re-heating zone downstream the process gas cooling section, configured for re-heating of the process gas, as well as a processes for condensation and production of sulphuric acid employing such a condenser.

    摘要： A converter having an exterior shell with a central axis, at least one gas inlet and at least one gas outlet. The exterior shell includes a base and an interior support structure. A number of vertically stacked catalytic chambers within the exterior shell are each in communication with one or more gas inlets and gas outlets. Each chamber is defined by an inner wall of the external shell, a permeable catalytic bed support platform, a lower division plate spaced below the platform defining a gas retention plenum and an upper division plate above the platform. At least one of: the platform; the upper division plate; and the lower division plate have a toroid surface symmetric about the central axis with an outer periphery supported by the inner wall of the exterior shell and an inner periphery supported by the interior support structure.
