Diesel Particulate Filter System

INNOVATION EDGE™: DIESEL PARTICULATE FILTER SYSTEM

Murphy has installed diesel particulate filter systems on its diesel-powered plant, reducing particle emissions by up to 99%.

Description

The emission regulations for diesel engines are becoming much stricter worldwide, making it necessary to modify current exhaust systems.

The diesel particulate filter is a system designed to remove soot from the exhaust gas of a diesel engine. The systems BA and BA-B range has been developed by Baumot.

Baumot’s diesel particulate filter system has two main versions – active and passive. The passive system has two different models for use on engines of different age – Baumot BA and Baumot BA-B. Murphy has retro-fitted both BA and BA-B models onto its diesel-powered plant.

The system captures soot by passing the exhaust gases through a series of filters. Over time, the soot builds up within the filters and is reduced to ash residue through the heat of the exhaust in a process known as regeneration.

With the Baumot systems, regeneration is possible with an exhaust temperature as low as 200°C. This makes them extremely versatile and suitable for diesel construction plant, where exhaust temperatures are relatively low in comparison to other diesel engine vehicles. 
 
Benefits

  • Eliminates up to 99% of construction plant particle emissions including hydrocarbons and carbon monoxide, protecting of the environment and local communities.
  • Economical, reliable and simple system, which is easy to maintain and completely passive, removing the need for additional heating elements.
  • Manufactured in accordance with Original Equipment Manufacturer (OEM) quality standards and includes a two-year guarantee.
  • VERT and TÜV-certified, as well as approved for use in London by the Energy Saving Trust.
  • Approved by the Dutch Vehicle Authority (RDW) and recommended in many other European countries, the USA and China.

Application

Hochtief Murphy Joint Venture (HMJV) retro-fitted the diesel particulate filter system onto its plant at the Crossrail Thames Tunnel C310. The £260m project comprised twin-bored tunnels which were 3km long and 6.2m in diameter, as well as the associated 1km approach structures.

HMJV was the first contractor across all Crossrail projects to install the diesel particulate filter system on its plant.

A single unit took two days to install and cost £3,000. Each unit was customised and tested for each individual engine type.

The diesel particulate filter system achieved a significant reduction in pollutants and particulates, contributing to a cleaner and healthier site environment for both the HMJV employees and the general public.
 
End user feedback

Having confirmed the high efficiency of the system, scientific investigations have also concluded that it facilitates a significantly healthier and less polluted environment.

“The use of the diesel particulate filter system on Crossrail Thames Tunnel C310 made a significant contribution to reducing our air emissions, helping us achieve full compliance with strict air quality standards and minimising the impact on our employees and local communities” – Stephen Marr, Murphy Group environmental manager.
 
Market potential

The system can be applied on any diesel operating vehicle or machine.

In 2000, PSA Peugeot/Citroën was the first company to make it a standard on passenger cars in anticipation of future Euro V regulations.
