Demulsifier “Para 2945” is designed for efficient dehydration and desalting of oil emulsions during their preparation at oil producing and oil refineries. The demulsifier is a balanced composition 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 2945” is produced in three grades A, M, N, depending on the composition, technical characteristics and conditions of use in accordance with the current technical specifications TU 2458-075-17423242-2012.
Used in services
The demulsifier “Para 2945” is constantly supplied to the preparation system through a dosing pump both directly from the drums and from reagent containers. The introduction of the demulsifier “Para 2022” is possible both at the wellhead and immediately before heating the oil feedstock at the preparation points.
The dosage of the demulsifier “Para 2945” depends on the specific requirements for the dehydration of the raw materials 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.
