Key purification system.
A Babcock Wanson TPC 200B Thermal Fluid Heater has been installed at Bridgnorth Aluminium Ltd as a key component in its exhaust air purification system.
Bridgnorth Aluminium is the UK's only manufacturer of lithographic aluminium strip with a purpose built, state of the art rolling mill and stretch levelling line in its Shropshire site. The company is focussed on maintaining a clean alloy system with its high purity aluminium alloy product range, which requires considerable technical knowledge of the process requirements.
As part of a planned expansion, Bridgnorth Aluminium recently purchased a refurbished rolling mill from overseas. As with all rolling mills that use oil as a coolant and lubricant, amounts of oil are emitted in their exhaust. In line with best practice, Bridgnorth Aluminium has installed an Achenbach Airpure exhaust air purification system to separate and recover hydrocarbons from the mill exhaust--in this case tetracene. Babcock Wanson's TPC 200B Thermal Fluid system forms an integral part of this process, heating the exhaust air to enable the AIRPURE system to recover virtually all rolling oil. Babcock Wanson not only supplied the new TPC 200B thermal fluid system, but was also involved in laying out the pipework and connections to the heat exchangers.
Peter Shrimpton, engineering projects manager at Bridgnorth Aluminium, comments on the TPC 200B Thermal Fluid Heater: 'The original manufacturers of the rolling mill equipment recommended that we use a thermal fluid system as part of the exhaust air purification system. We hadn't used this before and were unfamiliar with Babcock Wanson, but we've had no problems with it whatsoever; you simply switch it on and it works--simple as that!"
