Abstract: To test demulsifiers for crude oil/water emulsions as close as possible to practical conditions, the sample with the demulsifier is kept in a thermostatically controlled medium in whirling motion. Gravity causes the sample to move continuously to and fro in the sample container in a longitudinal direction and thereby mixed thoroghly.
