The new compact tubular Claus catalytic reactor-heat exchanger units and HTEM-containing heat exchangers are also disclosed. A process for recovering sulfur from a hydrogen sulfide-containing gas stream, employing the new tubular Claus catalytic reactor-heat exchanger unit, and in some instances a HTEM-containing heat exchanger, are also disclosed.
