SULPHURIC ACID PLANT

Waste Heat Recovery Solutions in Sulphuric Acid Production Process

Heat Recovery in Sulphuric Acid Production

Sulphur obtained is burned to make Sulphur Dioxide, which is further oxidised to make Sulphur trioxide in presence of a catalyst and finally hydrated to make Sulphuric acid.

Sulphuric acid making process results in generation of high temperature gases. To maximize energy recovery and acid yield , the gases are cooled in boilers, heat exchange equipment’s thereby generating high pressure steam which is further used to generate power.

Sulphuric Acid is mainly obtained by burning molten sulphur, from metallurgical off-gases or by decomposing spent sulfuric acid.

WASTE HEAT RECOVERY BOILER

For Sulphuric Acid Plant (Sulphur Combustion Process)

In the production of Low Ash Metallurgical Coke (LAMC), large quantities of heat is carried away by flue gases and the hot coke itself. We have successfully operating WH Boilers, Custom Built to suit the plant layouts & location of gas tapping.

We have used: HORIZONTAL-MODULAR single pass, VERTICAL - HORIZONTAL, VERTICAL - 2 PASS Construction to suit plant lay-out and installation costs.

WASTE HEAT RECOVERY BOILER

For Sulphuric Acid Plant (Wet Sulphuric Acid Process)

In WSA process SO2 gas is to produce at the operating temperature of the oxidation catalyst in the SO2 converter. Feed containing Sulphur are oxidized to SO2 by combustion and then cooled to the optimum catalytic conversion temperature in a waste heat boiler. The excess heat from this operation is recovered as steam. The catalytic conversion process reaction heat is recovered between the catalyst beds by superheating of steam.
