Demulsifier Para 1603

The demulsifier “Para 1603” is intended for the destruction of water-oil emulsions in the preparation of oil in the fields and refineries. It is a solution of the product obtained by the alcoholate polymerization of ethylene oxide on a condensed alkylphenol in an alcohol-aromatic solvent or toluene. The demulsifier “Para 1603” is produced in three grades A, B and C in accordance with the current technical specifications TU 38.401-58-295-2001 with amend. 1, 2, 3, 4, 5.

Used in services

Protection of technological equipment for the processing of hydrocarbon raw materials,


The demulsifier “Para1603” is constantly fed into the preparation system through a dosing pump directly from drums or from reagent containers. Entering the demulsifier is possible at the intake of the raw pump.


The dosage of the demulsifier “Para 1603” depends on the specific requirements for the dehydration of the raw material and on the stability of the emulsions. Typical dosages of the reagent can be considered 1 – 4 grams of demulsifier per ton of oil for refineries and 5-30 grams per ton of oil for oil producing enterprises.
