Heat Recovery in Sulphur Recovery Unit

Sulfur recovery unit is basically conversion of hydrogen sulfide (H2S) to elemental sulfur using Claus process with Condensers, reactors & Incinerator process. These processes involve burning H2S with air in a reactor furnace to form sulfur dioxide thereby generating Hot Gases.

The hot gas from the combustion chamber is quenched in a waste heat boiler that generates high to medium pressure steam.

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.
