V-tex® Technology

V-tex ERG Air Pollution Control

V-tex® is an outstanding, patented technology for gas scrubbing and stripping applications.

The V-tex® scrubber is especially suited to applications where traditional packed towers cannot be used because they would foul due to solids in the gas and/or liquid streams clogging up the packing media. And the V-tex® provides users with a highly efficient scrubber unit which is more compact than a traditional packed tower.

Thanks to the opposed-jet spray nozzle at the heart of the technology, V-tex® gas scrubbers offer flexible, robust operability and unrivalled, maintenance-free availability, across a wide variety of process applications.

V-tex® gas scrubber technology is available from ERG and its global network of licensees.

We also have a number of V-tex® pilot plants, which are available for hire as temporary scrubbing packages or to prove the V-tex® technology for your specific application.

Find out how the V-tex® works, download the technology and range brochures, and see examples of V-tex® scrubbing case studies in a variety of industry sectors.

Key Benefits

The V-tex® offers robust operation, even with dirty and solid-laden liquor streams, making it the scrubber of choice for arduous applications and where high availability, low maintenance operation is essential.

  • High availability and has no internals to foul – and vessel design allows for easy access to all internal parts for cleaning when used in the most challenging, solids-laden processes
  • Non-clogging spray nozzle technology – dual opposed and Cobra® spray nozzles
  • Consistent, predictable mass- and heat-transfer rates with exceptional gas flowrate turndown of over 10:1
  • Smaller volumes of spent liquor are generated for effluent treatment as V-tex® can scrub with viscous, high concentration liquors and slurries
  • High efficiency performance for particulate and soluble contaminant removal
  • Proven in a wide range of applications
  • V-tex® vessels can be manufactured in a large range of materials to suit the process requirements, including PP/GRP, cPVC/GRP, PVDF/GRP, ECTFE/GRP, Derakane® GRP, 316SS, Hastelloy C276
  • The configuration is ideal for skid-mounted, complete scrubbing packages
  • Easily integrated into a complete gas scrubbing or liquid stripping plant – used in combination with other ERG mass transfer technologies

V-tex® Technology Applications

These advantages of V-tex® technology make it especially suitable for two main types of scrubbing application.

  • Scrubbing where solids in the gas and/or liquid will block packing – the open scrubbing chamber and non-clogging spray nozzle design mean that a V-tex® scrubber operates much more effectively than a packed scrubber which will block up. ERG has successfully installed V-tex® scrubbers for a wide range of extremely challenging duties. These include:
    • Flue gas desulphurisation – SO2 scrubbing using 10-15% limestone and gypsum slurry as the scrubbing liquor
    • Halogenated silicon and boron compounds scrubbing where the gas hydrolyses to gelatinous or crystalline solids which are extremely difficult to handle and require the most robust scrubbing technology available
    • Syngases containing tars which can coat and clog packing materials but are treated effectively by V-tex® technology
  • Scrubbing where headroom is limited – the intense mass transfer in the V-tex® chamber achieves scrubbing to the same efficiency as a packed tower in only 30% of the height. So if the available height in your process building means a packed tower scrubber does not fit, a V-tex® could be the answer. This is particularly useful for localised scrubbing of vents in pharmaceutical and tech sector manufacturing.

V-tex® technology is also used for liquid stripping in waste water recovery and process water treatment.

Background To The V-tex® Scrubber

V-tex® technology was first employed in response to the tough gas scrubbing requirements of the nuclear industry, scrubbing both gaseous and particulate contamination while minimising the risk of fouling the scrubber internals and blocking the spray nozzles. The drive was to keep downtime to a minimum and reduce worker exposure risk to these hazardous maintenance activities.

With the partial privatisation of the UK nuclear industry in the 1990s, this unique patented technology has become available for gas scrubbing applications across other process industries.

Over the last 25 years, the technology has been developed and improved and today there are more than 400 V-tex® gas scrubbers and gas strippers in successful operation across a broad range of process industries and leading global companies.
