2WhyWhy remove sulphur from gas?Sulphur in gas:mainly presentas H 2 SH 2 S is highlypoisonous, corrosiveand converted to SO 2when burnedRemoval of ‘sour’gas ideally closeto the source

2WhyTypes of gasAmineacid gasHydrotreater/ SWSNatural gas(shale)Claustail gasAssociatedgasFuel gas
3OptionsMethods of desulpurisation(LoCat, Sulferox) convert H 2 S to sulphurusing a dual chelated iron catalyst
3OptionsMethods of desulpurisationRemove H 2 S and CO 2 from the feed gasstream and load the amine solutions.After regeneration (heat) the H 2 S and CO 2are recovered as a concentrated offgaswhich must be treated (incineration, Claus,<strong>THIOPAQ</strong> O&G, Sulferox, WSA, LoCat)
3OptionsMethods of desulpurisationDo not remove sulphur but recover sulphurby processing amine offgas to produceliquid sulphur (99.9% S)
2Why‘Remove sulphur (H 2 S)from sources 0,5-100 t S/daywith unfavourable gas compositions.’Associated GasNatural Gas
2Why● ‘Lean’ acid gases (
3OptionsHow does <strong>THIOPAQ</strong> O&G meet the challenge?CO 2 removal requiredNo CO 2 removal required
3OptionsWhen to use?<strong>THIOPAQ</strong> O&G as sulphur recovery unit (when CO 2 removal is required):‘Lean’ acid gases (30mol% H 2 S) treated economically up to 30 t S/day<strong>THIOPAQ</strong> O&G direct treat, AGRU and SRU in a single process:Natural/associated gas up to 80 barg treated economically up to 100 t S/day

4Process<strong>THIOPAQ</strong> O&G operations- Health & Safety● Safe:o No fired equipmento No high pressures reactoro No free H 2 S● No hazardous chemicals● No scheduled maintenance stops● On-stream factor typically > 99%
4ProcessRobust performance, appetite for fluctuations
4ProcessConsumables● NaOH or Na 2 CO3● Nutrients● Electricity● Cooling, heatingAnalysis● H 2 S analyzer● pH measurement● Redox measurement● Conductivity● Alkalinity● Solids concentrationOnlinemeasurement
4Process<strong>THIOPAQ</strong> O&G sulphur recovery efficiency● H 2 S-removal efficiency > 99.9 % from feedgasTypical H 2 S content in Treated Gas:o High pressure: H 2 S < 4 ppmvo Low pressure: H 2 S < 25 ppmv● Very low SO 2 emissions areachieved● Sulphur is recovered as:~ 5% (thio)sulfate in bleed~95% sulphur
6Bio-sulphur<strong>THIOPAQ</strong> O&G sulphur productionMelt to Claus specAgricultureProcess & Compression Systems
6Bio-sulphurThe end product: bio-sulphur● Unique hydrophilic properties● Excellent agricultural productsin form of liquid suspensionconcentrates● Biosulphur is much in demand
