Contractors E.G.Lewis were recently contacted by Petroplus at its Coryton refinery to apply a new protective coating to a caustic soda tank, which is part of the process in the refinery’s cracking plant. Because of the highly corrosive conditions, which are aggravated by the high temperature of the cracking process, E.G.Lewis approached Winn & Coales (Denso) Ltd for it recommendation of the most suitable protective coating.

Winn & Coales’ Archco-Rigidon 423D coating system was chosen, which is based on glass flake vinyl ester. In order to remove the 15-year-old former coating and to give good mechanical key for the Archco-Rigidon coating, the caustic soda tank interior was first shotblasted to Swedish Standard S.A.2.5 near white metal to achieve a minimum profile depth of 70 microns. The tank was then tested for chlorides before applying Archco Ridgidon PD2 primer

Petroplus is Europe’s leading independent refiner of petroleum products, with five refineries in Europe of which Coryton is the flagship and largest, E.G.Lewis & Co are a South Wales based company and are the resident painting contractors for the refinery and have been for the past eight years.
