Demulsifier Chemistries and Treating Tendencies

 

The vast majority of commercial emulsion breakers used in the field are blends of 2 or more components. It’s usually necessary to blend individual components in order to meet specifications. The numbers of demulsifier intermediates and finished blends are numerous and varied, because almost every oilfield emulsion is different.

 

Below are the main categories of demulsifier intermediates and their treating tendencies. Click here for more information on oilfield demulsifiers.

​​

  1. High RSN oxyalkylated resins:  Good dehydration of the oil, good water drop, prone to overtreat in high gravity crudes (SOT!)

  2. Low RSN oxyalkylated resins:  Good wetting properties, good water drop, generally more effective dehydration than high RSN resins

  3. Esters and high molecular weight polymers:  Slow water drop, fast brightening, prone to sludging and overtreat

  4. Polyols:  Broad demulsifier base used for wetting properties and good water quality, generally do not perform well as single component demulsifiers

  5. High molecular weight complex polyols (also known as Resin Ester Complex):  Slow water drop, good polisher, effective at low concentrations in blends

  6. Sulfonates:  Not prone to overtreat, especially on high gravity crude, fair wetting properties, fair general treating of oil, generally hurts water quality, require high treating rates

  7. Wetting Agents:  Help remove solids from interface which can stabilize emulsion, tend to overtreat/carry water if too much is used.  Use is highly over rated, if the proper EB intermediates are formulated surfactants are not necessary. If used, usually to overcome an EB deficiency
