P&P Sulphuric Acid Technology - Spent Acid Regeneration SAR

Our optimised Wet gas Sulfuric Acid WSA Process - Sulphur Oxidation Process SOP enables customers to produce clean air and sulphuric acid H2SO4 from waste gases or liquids containing sulphur - practically SO2 emission-free, with a conversion rate of over 99.999%.

P&P Glass tube heat exchanger GHX

The acid-proof P&P glass tube heat exchangers GHX are suitable for numerous tasks such as evaporation, condensation, heating and cooling of gaseous and liquid media.

Glass tube heat exchangers offer, among other things, the advantage that acid dew points can be undercut and so the residual heat in the flue gas is fully utilised to achieve maximum efficiency.


Decades of experience and the use of modern and environment-friendly technologies are the foundation for designing efficient, safe, ecological and economical plants. A central aspect of our design is always to achieve a high efficiency of the total energy consumption to minimise energy costs and environmental pollution. We are happy to provide you with further information!


P&P produces hardware and software solutions for DCS and PLC systems that are specially adapted to your applications. With our systems, your teams' work on difficult and dangerous tasks becomes more efficient, more precise, faster and safer. All control cabinets are manufactured and pre-tested by specialists in our own production. Talk to us!

P&P wet electrostatic precipitators (WESP)

P&P wet electrostatic precipitators (WESP) guarantee an extremely efficient reduction of submicron particles such as aerosols, acid mists, heavy metals, condensed metal vapours, organic substances and many more. P&P Industries AG develops custom-made wet electrostatic precipitators for your application. Our experience always guarantees the lowest possible emissions.
