Gas scrubbing, carbon filters, biofilters and bioscrubbers
ERG’s products and technology includes packed tower, tray, cyclonic and eductor scrubbers, V-tex™ gas scrubbing technology, bioscrubbers and variable throat venturi scrubbers. ERG also supplies carbon filters, biofilters and skid-mounted packages.
Odour and dispersion modelling consultancy, and front-end design studies
ERG can also offer maintenance contracts, 24-hour call out, pilot trials, odour and dispersion modelling consultancy, and front-end design studies.
Quench systems, scrubbers, heat exchangers, plume suppression and effluent treatment
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.
Pharmaceutical batch reactor vent gas cleaning
ERG’s innovative V-tex™ scrubber is particularly suited for pharmaceutical batch reactor off-gas scrubbing challenges that other technologies cannot match.
Pharmaceutical production in pressurised batch reactors presents a unique challenge for gas cleaning systems, as the gas flow rate varies dramatically as the reactor is vented. It is critical that off-gases are cleaned to high efficiency as they can be contaminated with noxious compounds, aerosols and particulates.
Unlike other traditional packed towers or venturi scrubbers, the V-tex™ excels under these variable conditions. The extraordinary property of the V-tex™ is that as the gas flow rate varies the mass transfer efficiency remains constant, making the V-tex™ a self-regulating absorption technology for variable gas flows. This is radically different to other scrubbers, which only operate effectively over a narrow flow rate range, and makes the V-tex™ uniquely suited to pharmaceutical applications.
Odour and air pollution control consultancy
Odour control and air pollution control can be achieved in many ways but choosing the optimum solution demands an in-depth understanding of many factors. Many leading organisations, both end users and contractors, draw on our 30 years of expertise.
Odour dispersion modelling
Our odour dispersion reports supply all the calculations and assessments required during the planning and design stages of a project. We also offer free advice on process requirements.
For clients with an existing facility, ERG offers an odour mapping service to determine the most significant sources of odour. Armed with this knowledge, a structured approach to combating emissions can be developed, and a properly optimised, site-wide odour management plan can be proposed.
When odour control equipment is installed, this can be targeted to the most odorous parts of the site first, maximising the benefit of the capital outlay, improving the site’s working environment and reducing the odour at the site boundary and, with it, odour complaints from neighbours.
For existing polluting processes, it is often helpful to carry out a pilot trail to establish the feasibility of treating the odour or air pollution using the proposed system.
ERG has pilot plants available offering a complete range of pilot trial options. These include V-tex™ scrubbers of different sizes and materials, and packed bed scrubber, venturi/quench and dry media (activated carbon and oxidizing media) systems.
