Sulphur Recovery Unit
Packages for the Claus unit.
Where the heat is
What the equipment has to do
- Reaction furnace and waste heat boiler form one unit, the MCC package, designed for refractory life, tube protection at the inlet and steam at the refinery's conditions
- Condensers cool to just above the sulphur dew point and drain liquid sulphur without plugging
- Reactors hold the catalyst at reaction temperature
- The incinerator reaches destruction temperature and recovers its heat


What we supply
- Major references across the globe, including one of India's largest SRUs
- MCC packages: combustion chamber, waste heat boiler, sulphur condensers and reactors
- Incinerator packages: incinerator chamber, waste heat boiler and superheater
- TGTU packages: combustion chamber and waste heat boiler for tail gas treating
- Fire-tube or water-tube construction, modular for site assembly, to the licensor's basis
Our Industrial Products
Thermal Systems provides MCC & Incinerator WHB packages for SRU in refinery
Fire Tube / Water Tube construction of WHB
Modular construction for ease of site assembly
Reaction Furnace (MCC) package for SRU
Incinerator Package for SRU
India’s leading manufacturer having highest number of successful installations for SRU application in major refineries
Reaction Furnace (Mcc) Package
For Sulphur Recovery Unit
In the Claus process, H2S-rich acid gas is burned in the reaction furnace, generating gas at around 1,300 °C. The furnace outlet gas is quenched in the MCC waste heat boiler, generating HP/MP steam.
Thermal Systems supplies complete Reaction Furnace (MCC) packages — burner, chamber, boiler and EBOP — in fire tube construction, with superheaters suitable for internal and import steam.
Incinerator Package
For Sulphur Recovery Unit
Tail gas leaving the SRU is thermally incinerated before discharge. The hot incinerator flue gas is cooled in a waste heat recovery boiler of fire tube or water tube construction.
Thermal Systems’ incinerator packages are of modular construction for ease of site assembly, with references including a 600 TPD SRU at Essar, Vadinar.
Tail Gas Treatment Unit Package
For Sulphur Recovery Unit
In tail gas treatment units, the treated gas stream is incinerated and its heat recovered in a waste heat boiler cum superheater.
Thermal Systems has supplied TGTU packages including 2 × 100 TPD TGTU boilers at HPCL Mumbai.
