Patent

CA 2275711

An on-line, thermo-chemical process for the dewaxing of oil export pipelines with the aid of a Nitrogen Generating System is described, wherein the treating fluid to be employed as dewaxing fluid comprises: a) a solution of nitrogen salts activated by emulsified acetic acid and designed to yield nitrogen and heat, and b) a solvent, which is the pretroleum oil being produced. The dewaxing treatment is effected at the same time as the pretroleum oil is produced, this leading to great savings in costs and energy.

L'invention concerne un procédé thermochimique, en continu, de déparaffinage de pipelines d'exportation de pétrole, au moyen d'un système produisant de l'azote, le fluide de traitement à employer en tant que fluide de déparaffinage comprenant: a) une solution de sels d'azote, activée par de l'acide acétique émulsionné, et conçue pour produire de l'azote et de la chaleur, et b) un solvant, constitué par le pétrole en cours de production. On exécute ce traitement de déparaffinage en même temps que l'on produit le pétrole, ce qui permet de réaliser de grandes économies en coût et en énergie.
