Abstract
SOis formed from a replenished circulating inventory of fresh and recycled SO. Also, a feed stream of replenished SOis heated by indirect heat exchange with a hot stream of SOand SOwhereby the hot stream is cooled for separating the two gases. The heated feed stream of replenished SOserves as a hot gaseous feed to a sulfur burner. This SOfeed is divided into two feed streams, one being oxygenated with pure oxygen and the other remains as an SOfeed. These feeds plus a feed of molten sulfur are concurrently and separately introduced into the sulfur burner where additional SOis formed via continuous exothermic reaction. Although heated, the oxygenated feed(s) of SObring in the needed oxygen for the reaction and the feeds of the oxygenated and non-oxygenated SOserve as a heat sink in the sulfur burner to reduce the temperature therein.
