Demulsifier Para 2500

Demulsifier “Para 2500” is designed for effective dehydration and desalting of oil emulsions during their preparation at oil producing and oil refineries. It 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 2500” is produced in accordance with the current technical specifications TU 2458-019-17423242-2008 with amend. 12.

Oil preparation

Application

The demulsifier “Para 2500” is constantly fed into the preparation system through a dosing pump both directly from the drums and from reagent containers. The introduction of the demulsifier “Para 2500” is possible both at the wellhead and immediately before heating the oil feedstock at the preparation points.

Dosage

The dosage of the demulsifier “Para 2500” 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 – typical dosages of the reagent can be considered 30 – 300 grams of demulsifier per ton of oil.
