Chemical & Pharmaceutical

ERG’s purpose-designed scrubbing systems are engineered to suit each application and client’s requirements.
From skid-mounted V-tex® and packed tower scrubber packages to major, on-site installations comprising quench systems, scrubbers (including V-tex®, packed tower and venturi scrubbers), heat exchangers, plume suppression and effluent treatment, ERG can offer a properly engineered and optimised solution for clients in the chemical, fine chemical and pharmaceutical sectors. Extensive range of process experience Our systems treat process and reactor off gases, storage tank vents, thermal oxidizer flue gases and pressurised steam processes where contamination is from
  • Acid gases (HCl, Cl2 , SO2 , HF, HBr),
  • Dust and aerosols (100 to <1 micron particle sizes),
  • Pharmaceutical “actives” and
  • VOC’s
And where the operating temperature ranges are from ambient up to 1200oC. Case studies The following selection of recent projects identifies the range of systems ERG has designed and installed. All are successfully operating to achieve the design duty.
  • Saffil Ltd: speciality chemical fibres manufacturer High temperature Hastelloy C276 quench vessel followed by two-stage HCl scrubber system to cool and condition the gas for an RTO, and then recover 4% HCl solution. Project value £550k, completed 2004.
  • Novartis: pharmaceutical manufacturing facility V-tex® scrubber skid-mounted package to treat high concentration batch release of HCl from a pharmaceutical process.
