Title
(EN) PLASTICIZED LATEX FORMULATIONS FOR IMPROVED PUMPABILITY
(FR) FORMULATIONS DE LATEX PLASTIFIÉ POUR UNE POMPABILITÉ AMÉLIORÉE
Abstract
(EN) Hydrocarbon streams, such as crude oil streams, may have reduced drag when an effective amount to reduce drag of a drag reducing composition is added to a liquid hydrocarbon, where the drag reducing composition includes a drag reducing latex comprising at least one plasticizer in an amount effective to improve the ability to pump the latex into a hydrocarbon composition or stream with assured flow of the latex. Latex formulations are known to cause agglomerated particles during pumping operations, and the agglomerated hard particles tend to plug check valves in injection pump equipment, but the inclusion of at least one plasticizer reduces or prevents such problems.
(FR) Selon l'invention, des courants d'hydrocarbures, tels que des courants de pétrole brut, peuvent avoir une traînée réduite lorsqu'une quantité efficace pour réduire la traînée d'une composition de réduction de traînée est ajoutée à un hydrocarbure liquide, la composition de réduction de traînée comprenant un latex de réduction de traînée comprenant au moins un plastifiant en une quantité efficace pour améliorer l'aptitude du latex au pompage dans une composition ou un courant d'hydrocarbures avec un écoulement assuré du latex. On sait que des formulations de latex provoquent une agglomération de particules pendant des opérations de pompage et que les particules dures agglomérées ont tendance à colmater les clapets anti-retour dans un appareillage de type pompe d'injection, mais l'inclusion d'au moins un plastifiant réduit ou évite de tels problèmes.
