High sulphur recovery at low cost with SmartSulf™
Process Principle: Thermal stage: acid gases are burnt with air to produce sulphur at high temperature thanks to Claus reaction. COS and CS2 hydrolysis: COS and CS2 from the process gases are hydrolyzed at high temperature in the first zone of the SmartSulf™ reactor operating in hot mode. Claus Reaction: Claus reaction occurs in the second zone of the hot mode SmartSulf™ reactor, where heat of reaction is continuously removed by thermoplates internals, thus increasing sulphur conversion.
Subdewpoint Claus reaction: Claus reaction plus further COS conversion is performed in the cold mode SmartSulf™ reactor operating below sulphur dewpoint producing liquid sulphur which is trapped on catalyst. Cycle switch: when cold mode SmartSulf™ reactor is saturated with liquid sulphur, a switch between hot and cold mode is performed automatically by rotating the two coupled 4 way valves, enabling the beginning of a new cycle.
• Performance above 99.5% sulphur recovery
• Complete COS and CS2 destruction at high temperature
• Proven technology, successfully operating in commercial plants since 1995
• Very low capital cost
• Low operation cost: process is fully automatic and needs nearly no follow-up
• Use of conventional open market Claus catalysts
• Easy retrofit to upgrade existing Claus units into SmartSulf™
Electrostatic coalescers allow to remove small water droplets which would remain emulsified and not separated in conventional separators, thanks to droplet size increase through coalescence in an electric field. Crude desalting can be achieved by injecting and emulsifying dilution water in the electric ...

Our Expertise, a global solution adapted to each case: Design suitable for Gas Plants, LNG Plants, Refineries, Biogas, Shale Gas and Syngas. Efficient and reliable amine sweetening processes: The AdvAmine™ series of processes • Can treat any sour gas composition • Achieves the most severe ...
Proserpack compact integrated heat exchanger – separator, simplifies NGL recovery by implementing 3 process steps (2 heat exchangers and the turbo-expander suction drum) in a single equipment item. The heat exchanger is a PACKINOX multi-fluid plate exchanger.
Ifpexol uses refrigerated methanol for the complete treatment (dehydration, NGL recovery and sweetening) of natural gas. The Ifpexol process is based on two independent steps. Methanol is used as hydrate inhibitor in a cold process for NGL extraction : The mixture of methanol and water recovered at the ...
Process Principle: Bulk H2S or CO2 removal from highly sour gas by high pressure cryogenic distillation - Conventional distillation column with no hydrates or solid products formation - Separated acid gases are recovered liquid at high pressure and easily pumped back into reservoir - Final sweetening ...
Benefits of Installing a MEG Recovery Unit - Strong increase in demand for natural gas leads to more development of deep offshore gas deposits with deeper wells, longer subsea pipelines, higher pressures and lower temperatures. Under such conditions, hydrate formation - that blocks flow lines and can ...
Drizo™ regenerates the glycol by solvent stripping instead of the conventional gas stripping. Solvent stripping allows to obtain much higher glycol purities than gas stripping (up to 99.998 wt% instead of the typical 99.95 wt%) and consequently allows to get much larger water dew point depressions: ...
In the frame of cooperation between TOTAL, IFP Energies nouvelles and PROSERNAT, PROSERNAT is today the licensor of the amine technology portfolio historically developed by SNEA(P), then ELF, now owned by TOTAL. AdvAmine™ processes have been developed for more than 50 years for all types of natural ...
By combining amine absorption with catalytic COS hydrolysis, COSWEET™ allows gas sweetening, either total (removal of both H₂S + CO₂) or selective (removal of H₂S mainly), with complete COS removal. The three steps of COSWEET™ process consists in: * Removing the bulk of the H₂S ...
