The project scope consisted of Design, Basic and Detailed Engineering, Manufacture & Supply, Complete civil works and Erection & Commissioning and guarantee run of complete Alkali Scrubbing System for tail gases from sulphuric acid plants to achieve the required outlet concentration of SO₂ as per norms laid by Rajasthan Pollution Control Board. The system as a whole is completely equipped with necessary instrumentation for safe and smooth operation of the plant.

Scrubbing systems for the two Sulphuric acid plants have a design gas handling capacity of 64,000 Nm³/h and 41,000 Nm³/h along with Alkali regeneration system having a capacity of 35 TPD of SO₂ removal.

The Scrubbing system comprises of a Quench, Two stage horizontal baffled scrubber and a ID fan. The Alkali regeneration system comprises of:  Lime reactors, Thickener and Vacuum drum filters.
