Tailored Abatement Systems for Chemical Process Emissions

Chemical Plant Air Pollution Treatment

ERG provides a wide variety of air pollution control systems for Chemical production plants. ERG’s purpose-designed scrubbing systems are engineered to suit each application and client’s requirements and are supplied with a process guarantee.

We have reference plants throughout the chemical industry, with sector experience in bulk chemicals, fertilisers, intermediates, fine chemicals, agrochemicals, heat-resistant materials manufacture, speciality chemicals, petrochem and consumer products.

Applications

ERG’s abatement packages are typically installed to treat vents from storage tanks, reactors, vent lines/LEV systems, liquid waste handling, packaging areas and thermal oxidisers. In many cases, a skid-mounted scrubber package is required, though ERG can also arrange site installation and commissioning.

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, rubber
VOCs – MEK, methyl chloride, THF, ethyl acetate, acetone, etc

Technologies

Our vent abatement systems are based on one or more of the following technologies. Each package is bespoke: designed and manufactured to the specific project requirements.

Packed tower scrubbers – for acid gases, basic gases, some dusts, some VOCs
V-tex® scrubbers – for acid gases, basic gases, some dusts, some VOCs VOCs, and especially suitable to gelatinous hydrolysis products
Venturi scrubbers – for high concentration or fine dust
Carbon filters – for VOCs and solvent abatement
Quench systems – for adiabatically cooling high temperature gas for further wet scrubbing
Tray scrubbers – typically large flowrate low concentration gases and dusts
Thermal oxidation – waste solvents and VOC-rich vent gases
Low temperature DeNOx – for NOx abatement to high efficiency

ERG is skilled at system integration, adding additional abatement techniques from third-party vendors into our systems. Examples include bag filters, ceramic filters, RTOs, SCR/SNCR de-NOx, liquid effluent treatment.

Meeting Exacting Specifications

ERG’s design and project management teams are highly experienced at delivering packaged plant which meets the chemical industry’s needs.

All design and procurement is managed according to our ISO9001 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.
Safety in design and operation is our highest priority. We work with the main contractor, designer and end user to ensure the safety case documentation, HAZOP, etc are conducted thoroughly and efficiently.
