CONDENSERS

Is the process gas mass velocity through each of your Condensers Aligned with Best Practices?
RUNDOWNS AND SEAL LEGS
Condenser Rundowns and Seal Legs must be jacketed (i.e. steam, glycol, etc.) to ensure that sulfur solidification does not occur. For steam jacketing, it is important to ensure that all steam traps are hot by taking a piece of solid sulfur, touching the surface of the trap, and observing that it melts. Catalyst beads, finings, corrosion products, and sulcrete can plug up the seal leg and therefore frequent observation into the ‘look-box’ should be performed to ensure steady flow of the produced liquid sulfur. Any abnormalities in the sulfur flow may be due to partial plugging of the seal leg, failure in part of the jacketing, and/or a tubesheet leak in the upstream Condenser due to a tube or tube sheet leak, which causes sulfur to solidify in the outlet section.
Seal Legs are often overlooked in the SRU – Are yours Properly Sized?

CATALYTIC REACTORS
Claus Reactors contain Alumina and/or Titania catalysts that must be protected from Claus contaminants/poisons, thermal shock (sulfur fires), amine, condensed water, liquid sulfur, and soot. Claus catalyst can be permanently poisoned by BTEX, heavy hydrocarbons, amine, and methanol. The thermal shock from sulfur fires, as well as condensed water and amine, can destroy the integrity of the catalyst, while liquid sulfur and soot only plug the catalyst pores (reversible).

THE VIRTUAL SRU

SRE has partnered with Virtual Materials Group (VMG – A Schlumberger Technology), allowing SRE to use the powerful VMG Sulfur Plant simulation software in-field (Symmetry Process Software Platform). Using years of accumulated SRE sulfur unit data, our team is able to accurately model any given SRU. In conjunction with our field results, the models provide important process values such as Reaction Furnace adiabatic temperature, Reactor bed dewpoints, and catalyst activity.
