Abstract

An apparatus is provided for the condensation of sulphur vapor and for the separation of sulphur droplets from a gas flow, preferably from the reaction gas flow from a Claus catalyst. Such apparatus comprises a vessel, a nest of tubes arranged in the vessel between tube plates, pipe connections at the vessel for the supply and discharge of a coolant flowing around the nest of tubes and an inlet pipe connection and an outlet pipe connection for the gas flow at the vessel, upstream and downstream of the said nest of tubes, respectively. Positioned in the vessel is a sulphur separation unit through which the sulphur-containing gas flows and on the surfaces of which sulphur vapor condenses and/or liquid sulphur collects and agglomerates. Sulphur discharge openings are provided in the bottom of the vessel on both the upstream and downstream sides of the separation unit.
