Abstract

In a sulfur condenser and degasser system associated with a Claus furnace, the condenser comprises a wound cross-countercurrent heat exchanger. Liquid sulfur is passed into the top of the condenser as reflux so that ascending sulfur droplets can be coalesced and the condenser can act as a rectifying column. The degassing is preferably carried out substantially simultaneously with the formation of liquid sulfur.
