How long does it take for the SigmaPure skid to make our foaming stop?
Answer – The plant’s response time to D-Foaming treatment will depend on: the rate at which the surfactant concentration is reduced, (generation/ingress versus contaminant removal rates), and any amplifying or inhibiting contaminants in the solution,i.e., solids, antifoam, liquid hydrocarbon. In a typical application where the surfactants causing the foaming were generated over a long period of time with antifoam being added to keep the plant under control, the plant would be expected to respond within 6-12 hours. Keep in mind that “response” means a reduction in foaming symptoms, not complete elimination. Normally, plant operations requires antifoam injections on an “as needed” basis during treating. Antifoam masks the affects of foam causing surfactants so their removal is inhibited every time an injection is made.
