It passed the bottle test. It passed the dose-response curve. Then it hit the field — and the water didn’t drop. If that sounds familiar, you’re not alone. In my line of work, “it worked in the lab” is one…
It’s late afternoon at a separator. BS&W is creeping up. The operator’s first instinct — raise the demulsifier pump stroke. More chemical, faster separation. Right? Wrong. More often than not, that instinct makes the emulsion stronger. The curve nobody drew…
Many people don’t understand what reverse demulsifiers are. There are many blind spots due to a lack of understanding of the principles of reverse demulsifiers and other related formulas. The term “reverse demulsifier” originates from the explanation of demulsifiers, which…
What are crude oil demulsifiers ? What are their characteristics? The mechanism of crude oil demulsifiers is a phase transfer-reverse deformation mechanism. After the addition of a demulsifier, a phase transition occurs, meaning it can generate a surfactant of the…
The mechanism of crude oil demulsifiers is a phase transfer-reverse deformation mechanism. Upon addition of the demulsifier, a phase transition occurs, generating a surfactant of the opposite type to the emulsion formed by the emulsifier (reverse demulsifier). This type of…
Demulsifier is a surfactant that destroys emulsion. Demulsifiers mainly destroy the emulsion by partially replacing the stabilizing membrane. used as a dehydrating agent, it can remove the water from crude oil and heavy oil to make the water content meet…
First, the main source of oilfield wastewater A large amount of wastewater will be produced in the process of oilfield exploitation, especially in large-scale oilfield exploitation, and the water content of produced liquid is relatively higher. Oilfield mining wastewater mainly…
Reverse demulsifier can effectively improve the interfacial tension of oil-in-water (W/O) or oil-in-water (O/W) emulsion, so that the colloidal particles in the sewage lose their stable repulsion and attraction, and eventually lose their stability and form floc, and further through…
