Demulsifier Para 2946

Demulsifier “Para 2946” is designed for effective dehydration and desalting of oil emulsions during their preparation at oil producing and oil refineries. The demulsifier is a specially selected mixture of surfactants, including oxyalkylated phenol-formaldehyde resins, copolymers of ethylene and propylene oxides in an aromatic, alcoholic or combined alcohol-aromatic solvent. 

The demulsifier “Para 2946” is produced in two grades A and M depending on the component composition and conditions of use and in accordance with the current technical specifications TU 2458-076-17423242-2012.

Used in services

Oil preparation


Demulsifier “Para 2946” is used for dehydration of persistent water-oil emulsions even at temperatures of 10-25°C. The reagent is also effective under conditions of thermal separation of water-in-oil emulsions. The demulsifier is constantly fed into the preparation system through a dosing pump both directly from the drums and from the reagent tanks. The introduction of a demulsifier is possible both at the wellhead and immediately before heating the oil feedstock at the preparation points. 


The dosage of the demulsifier “Para 2946” depends on the specific requirements for the dehydration of the raw material and on the stability of the emulsions. Depending on the stability of oil emulsions and the requirements for the amount of dehydration, the degree of technical support of preparation points, 20-70 grams of a demulsifier per ton of oil can be considered typical reagent dosages.
