Abstract
A question and answer session presented at the NPRA Conference (1996) on sulfur recovery (sulfur plants) covers experience with the use of above ground tanks vs. pits for the storage of liquid sulfur; source and disposition of the purge gas; the use of monolithic castable refractory lining as the internal refractory in sulfur furnaces; experience in using oxygen-enrichment technology for sulfur recovery units; limitations on using oxygen enrichment; methods used to control or minimize COS and CS2 formation; the lowest Claus converter bed temperature permissible before feeding sour gas to the reactor furnace during start-up; the use of type pilots or other technology in SRU applications; typical life of Claus catalyst; typical turnaround frequency for sulfur recovery units; procedures used when a sulfur recovery unit is shutdown for maintenance; and monitoring of SO3 presence out of the SRU reaction furnace.
