Abstract

"PROCESSO PARA A REDUçãO DA VISCOSIDADE DE HIDROCARBONETOS OU SUAS MISTURAS". é descrito um processo para a redução da viscosidade de hidrocarbonetos ou suas misturas, como os petróleos ou suas frações que apresentam nas condições de aplicação uma viscosidade que se deseja reduzir. O processo compreende adicionar ao hidrocarboneto ou suas misturas uma proporção entre 1 e 20% em partes em peso de um ácido orgânico fraco com pelo menos um carbono metilênico, puro ou em mistura com um solvente orgânico na proporção entre 1 a 99% em partes em peso. O processo se aplica principalmente a petróleos e suas frações, na etapa de produção ou de transporte, ou ainda a frações de petróleo como óleos lubrificantes, ou a quaisquer líquidos industriais viscosos."PROCESS FOR REDUCING VISCOSITY OF HYDROCARBONS OR THEIR MIXTURES". A process for reducing the viscosity of hydrocarbons or mixtures thereof, such as oils or fractions thereof which have a viscosity to be reduced under the conditions of application is described. The process comprises adding to the hydrocarbon or mixtures thereof from 1 to 20% by weight of a weak organic acid with at least one methylene carbon, pure or in admixture with an organic solvent from 1 to 99% by weight. Weight. The process applies mainly to oils and their fractions, at the production or transport stage, or to petroleum fractions such as lubricating oils, or any viscous industrial liquids.
