Koppers - Case Study


Courtesy of ERG (Air Pollution Control) Ltd

Client: Koppers Europe Ltd, Scunthorpe, Lincolnshire
Application: Naphthalene fume scrubbing from naphthalene and oil blend storage tank vents
System description: The fume scrubbing system treats the air which is naturally vented from bulk storage tanks and road-tanker filling stations and removes the odorous naphthalene vapour from it. The V-texTM scrubber uses oil at >40oC to scrub the air, dissolving the naphthalene in it. The V-texTM scrubber is ideally suited to the application as its operation is robust and can tolerate solid naphthalene crystals in the scrubbing oil.
