About

ERG has for over 30 years been supplying systems and services to combat air pollution and odour problems. We provide turn-key tailor-made solutions optimised to give the best technical solution for the lowest capital and running cost. We have more than 600 systems currently in operation. New industries using ERG's expertise include composting/recycling operations and energy from waste plants. With an unrivalled range of equipment types, it means we are ideally placed to help you comply with both current and foreseeable legislative requirements. Our range includes biofilters, CIF's, bioscrubbers, venturi, packed towers and vortex scrubbers. Our solutions cover both wet and dry scrubbing systems along with the Odorgard catalyst enhanced system. Draw on our expertise not only for odour control systems but soluble contamination capture and recovery as well as hazardous flue gas cleaning systems. In addition, the V-tex vortex scrubbing, stripping and condensing technology gives us an added dimension for particulate removal and VOC contamination abatement. Finally, we have a comprehensive maintenance service to help keep your odour control and industrial air pollution control equipment running efficiently.

ERG's V-texTM technology selected by major pharmaceutical

ERG (Air Pollution Control) Ltd. in Horsham has just installed another new V-texTM gas scrubber unit at a major pharmaceutical manufacturer in Ireland. Some pharmaceutical manufacturing processes can produce gases laden with aggressive acid and volatile organic compounds (VOCs). These must be treated before they can be safely vented to atmosphere. The V-texTM scrubber is ideally suited to this tough gas cleaning challenge, and is designed to remove greater than 99% of the acidic contaminants.

Hot off-gases from the pharmaceutical reactor are pumped tangentially into the V-texTM scrubber chamber, where they create a vortex. Simultaneously, caustic liquor is injected into the top of the V-texTM chamber via a patented cobra nozzle unit that creates a planar atomised spray. The action of the liquor droplets passing through the gaseous vortex generates intensive gas contact allowing the caustic to react with, and neutralise, the acids in the off-gas stream. The neutralised gases are then passed to the facilitys existing stainless steel rich vent system, where the VOCs are treated and recovered.

The design of the V-texTM scrubber had to meet tough requirements set by the client. The vessel was constructed from multiple layers of laminated GRP to comply as a category 4 rated pressure vessel operating at up to 4 bar and 90C. It was then lined with ECTFE (ethylene chloro-trifluoroethlyene) for extra chemical and corrosion resistance. The whole unit had to be ATEX rated for operation in an explosion risk area.

From the clients point of view V-texTM offered significant advantages, not least of which is the flexibility of a high turndown ratio when handling wide variations in the gas flow rate from the reactor. In addition, it has a lower energy consumption than a venturi scrubber, is a compact design, making for easy installation in height restricted or tight locations and has an almost maintenance free operation when compared to packed tower scrubbers owing to the absence of any packing material to foul.

James Scott-Bowden, Managing Director of ERG, commented: V-texTM scrubbers really are the optimum and most economic technology for tough pharmaceutical gas cleaning applications. We already have dozens of installations at leading pharmaceutical companies, however the high technical specification demanded by this latest project demonstrates that V-texTM units can be designed to operate in most challenging production environments.
