- ERG enjoying significant Middle East sales growth through winning formula
October 2011 – Horsham UK. ERG (Air Pollution Control) Ltd, the UK-based supplier of odour and air pollution control systems, reports record performance through its Middle East office, with first half-year sales up 75% over the same period last year.
The key driver to this success has been strong performance in supplying odour control systems to the wastewater treatment sector in the UAE. This performance has been built on excellent working relationships with leading regional contracting customers, particularly Metito and JOG Union Engineering.
This follows ERG's recent success with industrial gas treatment projects in the Middle East, most notably the methane pre-treatment plant for Qatar-based QAFCO in 2010, where ERG's venturi scrubbers clean particulates from methane which is fed direct from the undersea gas wells to QAFCO's fertiliser production facility.
Examples of recent wastewater sector projects include the completion of two-stage chemical scrubbers providing odour control at the pumping stations on islands 3 and 4 of the Al Marjan Island resort development in Ras Al Khaimah for JOG Union. This was completed on time against an accelerated schedule. ERG is also currently supplying multiple odour control units for phases 1 and 2 of the Abu Dhabi sewer rehabilitation schemes for Metito.

Reviewing the results, Middle-East Director, Richard Hanson commented: "We are particularly delighted to report strong Middle East growth in odour control for the wastewater sector, as this is ERG's core business. By sourcing engineering designs and precision components from the UK where there is depth of experience and combining this with local Gulf manufacture of bulky vessels and tanks, and using ERG's local project management and commissioning team, ERG has a winning formula delivering leading technology at competitive prices, all tailored to local market requirements and managed through a client interface via our Middle East office."
- ERG delivers FGD (flue gas desulphurisation) system for Ferrybridge Carbon Capture project
August 2011. Horsham UK based ERG (Air Pollution Control) Ltd has installed a £¾M flue gas desulphurisation unit to Ferrybridge power station as part of a carbon capture pilot project.
The ERG system acts as a final flue gas “polishing” stage to reduce SO2 and particulate concentrations to required levels before the flue gas is passed to a downstream “post combustion carbon capture” unit which will remove 100 tonnes of carbon per day from the flue gases emitted by the Ferrybridge coal fired power station.
The unit was supplied to Doosan Power Systems, appointed by Ferrybridge owner, SSE (Scottish and Southern Energy), for the engineering design and operation of the carbon capture plant at the Yorkshire power station.

The main components of the ERG system are a two-stage “polishing” tray scrubber and a direct contact packed tower cooler. ERG has also supplied additional equipment such as recirculation pumps, a fan, scrubbing liquor storage tanks, and ancillary instrumentation and control equipment. The unit will treat about 30,000m3/hr of flue gas, and will remove 80% to 90% of the SO2 and particulates present in the flue gas to condition it for the downstream carbon capture process. The unit is scheduled to be operational in 2011.
The scrubber and the cooler are each 9m tall and 2m diameter and are constructed from GRP / Polypropylene to ERG's specification. The Ferrybridge carbon capture project is a pilot trial to prove the technology for post combustion carbon capture by treating a 1% side stream of the flue gases from the power plant, making it Europe's largest post carbon capture project of this type, and demonstrates the participants' commitment to clean coal technology.
The completion of this project further consolidates ERG's position as a leader in the design and supply of industrial air pollution control systems for the process industries. Other major industrial projects that ERG has completed in the last year include: a methane conditioning plant for the world largest fertiliser production site in Qatar, a hydrochloric acid fume scrubber for a petrochemicals refinery in Kazakhstan, a silicon tetra-fluoride scrubber for phosphate fertiliser production in Egypt, a solvent recovery scrubber for a synthetic textiles manufacture, and treatment plants for cleaning specialty gases used in optical fibres and electronics both in South Korea and the UK.
- Air quality maintained at seaside resort
August 2011. ERG (Air Pollution Control) has completed a major £300k project to refurbish the odour control plant at the East Worthing Wastewater Treatment Works belonging to Southern Water. The project was undertaken on behalf of main contractor Barhale Trant Utilities, and is in addition to the regular preventative maintenance programme that ERG carries out on behalf of Southern Water.
The main task for ERG was the replacement of two large odour control wet chemical scrubbers. These were housed inside a large portal frame building where there was extremely restricted access. This provided the project team with their greatest challenge, as the old scrubbers had to be dismantled in situ. The newly fabricated replacement units were then craned in sections into the building via the roof, which had to be opened up especially for the task. This was an extremely delicate operation, as at times there were only inches to spare, as the vessels were manoeuvred past internal beams and structures.

In order to guarantee an uninterrupted continuous operation, Nick James, ERG's senior project manager, explained “The scrubbers, which operate in parallel, were replaced one at a time, with the first new scrubber being commissioned and brought into service before the second old unit was decommissioned and removed”.
The new scrubbers are constructed from a composite of PVC/GRP with polypropylene internal packing. Weighing approximately 5 tonnes, each measures 3 metres in diameter and 9 metres tall.
With each scrubber capable of treating over 62,000 m3/hr of odorous air, the refurbished odour control system is now operating with an H2S removal efficiency of >99%, thereby helping reduce the impact of odours in this sensitive urban location near a popular tourist location and close to the beach.
