FROM SPEC TO PROTECT WHITE PAPER FINDING A BETTER LINING FOR FREE WATER KNOCKOUT VESSELS Flake-Reinforced Novolac Coating Extends Lining Lives by Ted Moore, Oil Gas Project Development Manager, Sherwin-Williams Protective Marine (Retired) and Travis Crotwell, Business Development Manager – Upstream Oil Gas, Sherwin-Williams Protective Marine Inside free water knockout vessels (FWKOs) used in the upstream oil gas market, high pressures and temperatures separate oil, gas and water from fluids extracted from the earth. These stresses present challenges to the coatings used to line such vessels. The coatings may crack and peel under the burdens of elevated pressure and heat. Add to that corrosive attacks from some of the most aggressive materials to come out of the ground, and it might seem like no coating can stand a chance at remaining adhered inside an FWKO over the long term. Figure 1. To test the performance of Nova-Plate® 360, three F WKOs were lined with the flake-reinforced coating. That may be what a major multinational oil company originally thought when it ran into troubles with LINING TROUBLES the linings used to protect the interiors of multiple FWKOs in use at its upstream production facilities. The Linings inside FWKOs are subject to some of the most novolac-based tank linings were failing prematurely aggressive conditions in the upstream market. Exposure to – with significant cracking, blistering and peeling hot extracted fluids, continuous operation at temperatures evident during regular cleanings. The deterioration was of 120°F (
