Abstract

sistemas e métodos para avaliação de inibidores de deposição de asfalteno. métodos para determinação da eficácia de um inibidor de deposição de asfalteno são relevados em aplicaçõs de campos petrolíferos. tais métodos compreendem tipicamente as etapas de introdução de um fluido de poço de petróleo a um sistema microfluídico/milifluídico; introdução de uma mistura de um inibidor de deposição de asfalteno e transportador no sistema microfluídico/milifluídico, introdução de um agente de precipitação, compreendendo tipicamente heptano ao sistema microfluídico/milifluídico, então observando a presença ou ausência de agregação de asfalteno no sistema microfluídico/milifluídico.
