We have extensive experience in process simulation studies for sulphur recovery facilities using our sulphur plant simulation program as well as other industry standard simulation programs (ProMax™ and others). These simulation studies can be used to support a wide variety of engineering studies including:

  • Determining the current SRU recovery efficiency of your plant using actual recent plant data Predicting the reaction furnace performance for the processing of specific acid gas compositions
  • Determining the effect of catalyst activity on overall plant recovery performance

The simulations will reflect the expected performance with new catalyst (“start of run”) and deactivated catalyst (typical for “end of run”) conditions. The effects on the Claus reaction and the COS and CS2 hydrolysis rates will be evaluated.

Determining the specific operating conditions required for optimum recovery efficiency (converter and condenser temperatures etc.)

  • Identifying and determining the effect of various plant problems on recovery efficiency capability (air flow control, leaking switching valves, poor bed regeneration etc.)
  • Evaluating the impact of other possible plant emission sources (pit vent, H2S in incinerator fuel gas etc.) on overall plant emissions
  • Providing detailed material and heat balances for future detailed design engineering
