It has been surprisingly discovered that the use of two different conventional defoamers give surprisingly and synergistic results when used together to suppress oil-based foams. The use of both a fluorosilicone together with a non-fluorinated siloxane give both reduced liquid carry over into a gas stream and reduced gas carry under into a liquid stream in a separation process. The fluorosilicone and non-fluorinated siloxane may be added together to a system producing an oil-based foam, or separately in any sequence. On some oil-based foams, the inventive blend achieves a level of performance unattainable by conventional defoamers at any dose. In most cases, better overall performance is obtained with the inventive foam suppressing blend at lower doses and less cost than with conventional defoamers used single.
