ERG’s purpose‑designed scrubbing systems are configured for storage tank vents, reactors, vent lines / LEV systems, liquid waste handling, packaging areas and VOC‑rich process exhausts, as well as vents from thermal oxidisers. Using combinations of wet gas cleaning, quench, carbon adsorption, thermal oxidation and DeNOx technologies, these systems are engineered to meet site‑specific performance and engineering standards.
Typical contaminants which we treat include:
Acid gases – HCl, Cl₂, Br₂, COS, HCN, SO₂, H₂S, mercaptans, etc.
Basic gases – NH₃, amines, etc.
Silicates – SiO₂, H₂SiF₆, SiF₄, SiCl₄, etc.
Dust and aerosols – 100 to <1 micron particle sizes; mechanically and chemically generated dust including catalysts, zeolites, PTA and rubber.
VOCs – MEK, methyl chloride, THF, ethyl acetate, acetone, etc.
ERG has particular experience treating halogenated semi‑metals such as BCl₃, SiCl₄ and SiF₄, where difficult‑to‑handle gelatinous or solid precipitates can form on contact with the scrubbing liquor, creating the potential for fouling and system blockage. Download our case studies to read more.
Our vent abatement systems are based on one or more of the following technologies, with each package bespoke – designed and manufactured to the specific project requirements.
Technology selection is based on contaminant speciation, flow rate, temperature, solvent loading and required removal efficiency, ensuring each gas cleaning system is optimised for the specific pharmaceutical or fine chemical duty.
ERG’s design and project management teams are highly experienced at delivering packaged plant which meets our clients’ high standards and precise specifications. All design and procurement is managed according to our ISO 9001 procedures. All manufacturing and assembly is to the agreed codes and project specifications, managed through and certified against the project Quality and Inspection & Test Plans.
All equipment is fully certified and documented in accordance with applicable European Standards, and CE marked accordingly. Vessels can be supplied to BS EN 13121, PD 5500 or ASME VIII as appropriate, and packages CE marked to the Pressure Equipment (2014/68/EU) and ATEX (2014/34/EU) Directives depending on the specification requirements. Full materials traceability can be provided to include BS EN 10204 2.2 or 3.1B certification.
Every ERG package has materials selected to match the specification. All systems are mechanically designed for the operating and design pressures (from FV to +10 barg) and temperatures (ambient upwards to suit the process). Common materials selections are listed in the table below, though alternatives are available to suit the process requirements.
As a specialised gas cleaning supplier, our typical scope includes:
Installation and commissioning are also available if required – phone support during this phase can be arranged. Plastic and GRP vessels are manufactured by ERG’s sister company ERG Plastic Fabrication, and skid assembly and testing are managed at the facility in West Sussex.
Our standard (12 months) or extended warranty guarantees the mechanical and electrical parts against defects. In addition, our Maintenance department can assist with routine, shut‑down or emergency maintenance, helping to maintain gas cleaning performance and availability over the life of the plant.
Our customers in this sector include major pharmaceutical, healthcare, agrochemical and fine chemical manufacturers, as well as specialist contract manufacturers.
Contracts can be placed direct by the site owners, although we frequently work through main contractors including Jacobs, PM Group, Doosan and Doosan Babcock.
