Through a combination of specialized analytical methods, engineering tools (including Sulsim^®), and process knowledge, Sulphur Experts can provide detailed information and recommendations on a wide variety of processes. Common performance evaluation types include:

Raw Gas or Liquid Streams  

• Detailed and accurate stream compositions for use in the design of downstream process units

Amine Sweetening Units (in conjunction with Amine Experts)

• Detailed and accurate material balances, including raw inlet gas, sweet gas, flash gas, and acid gas

Sulphur Recovery Units (Modified Claus, Sub-Dewpoint Units and Others)

• Detailed heat and material balances

• Accurate interstage and overall conversion and recovery efficiencies

• Reaction furnace operation (contaminant destruction efficiencies, temperature calculations, conversion efficiencies, formation rates of additional species)

• Catalyst Beds (catalytic activity, dewpoint margins, hydrolysis rates)

• Reheaters (heat duties, burner stoichiometry checks)

• Condensers (heat duties, sulphur production rates, entrainment checks)

• Metering (verification of plant metering, Claus ratio checks)

• Analyzers (accuracy checks for feed forward and feed back analyzers)

Selective Oxidation Units (SuperClaus™)

• Unit conversion, selectivity, and yield values

Amine-based Tail Gas Units

• Tail Gas Heater / Burner (confirmation of burn stoichiometry, CO/H₂ formation rates; evaluate for oxygen and hydrocarbon breakthrough

• Hydrogenation Reactor (calculation of sulphur loading and reactor demand for reducing gases (H₂/CO), catalytic activity, residual sulphur concentrations)

• Wasteheat Exchanger (heat duty)

• Quench System (water balance)

• Absorber (H₂S and total sulphur content of the absorber vent gas, H₂S and CO₂ absorption rates, calculation of CO₂ slip).

Incinerator

• Destruction efficiencies

• Emission rates

• Analyzer accuracy checks

• Optimization (greenhouse gas emission reduction, fuel conservation)
