Demulsifiers
|
Demulsifier selection should be made with the emulsion treatment system in order to obtain the best one; through making several sets of tests that maybe necessary at different concentrations, temperatures, water cuts etc…. One way to reduce overdosing is to conduct field-optimizing tests periodically to determine optimum demulsifier rates. Oil and water emulsions need to be efficiently and quickly separated and there must be a period of continual, moderate agitation of the treated emulsion to produce contact between and coalescence of the dispersed droplets, as well as quiet setting period. |
