Title (EN) DEMULSIFIERS FOR SEPARATION OF WATER FROM OIL AND PREPARATION THEREOF
(FR) DÉSÉMULSIFIANTS POUR SÉPARER L'EAU DU PÉTROLE ET LEUR PRÉPARATION
Abstract: front page image
(EN)The present invention relates to novel crude oil demulsifier comprises a copolymer of styrene with pyridine or a carboxylic acid or its salt selected from methacrylic, acrylic, maleic or fumaric acid with molecular weight in the range of 10000 to 600000 Daltons, dose in the range of 20-1000 ppm. The invention further relates to a process for demulsification of crude oil by treating crude oil with the copolymer in the range of 20-1000 ppm in the temperature range of 25-40°C by shaking to obtain demulsified crude oil having crude oil with < 1% water, and Water < 100 ppm oil.
(FR)La présente invention concerne de nouveaux désémulsifiants de pétrole brut comprenant un copolymère de styrène utilisant la pyridine ou un acide carboxylique ou son sel choisi parmi l'acide méthacrylique, acrylique, maléique ou fumarique dont le poids moléculaire est compris entre 10 000 et 600 000 Daltons, dans une dose comprise entre 20 et 1000 ppm. L'invention concerne également un procédé de désémulsification du pétrole brut consistant à traiter le pétrole brut avec le copolymère compris entre 20 et 1000 ppm à une température comprise entre 25 et 40 °C par agitation afin d'obtenir un pétrole brut désémulsionné, le pétrole brut ayant une teneur en eau < 1 %, et l'eau ayant une teneur en pétrole < 100 ppm.
