Acid Production System

We recommend the combination of ionic liquid desulfurization and industrial
sulfuric acid process to treat the lead smelting flue gas to meet the standard
emission and produce industrial sulfuric acid.
Side-blown furnace flue gas purification: adopt adiabatic evaporation dilute
acid cooling process, side-blown furnace flue gas purification into the
automatic gas separation system to automatically adjust the amount of gas to be
divided, 50% of the flue gas into the composite amine SO2 capture
desulfurization system, 50% of the flue gas into one-turn one-suction acid
production system

RE TECH – the name that is synonymous with innovation, excellence, and
sustainability in the field of metallurgy and recycling!

Introduction of Main System
Flue gas purifying system
The flue gas from the side-blown furnace electric dust collector, enters the
high efficiency scrubber, contact with the spray liquid to cool down, remove
most of the mineral dust and other impurities, enter the packed scrubber tower,
the packed scrubber tower to spray liquid scrubbing further dust removal, the
temperature is reduced again, the flue gas after the second scrubbing into the
automatic gas separation system, 50% of the flue gas into the composite amine
SO2 capture desulfurization system, 50% of the flue gas into the flue gas
cooling tower, cooling tower to spray liquid scrubbing further dust removal to
cool down, then into the two-stage electric mist eliminator to remove acid mist
and other impurities before entering the next step of dry suction section.
