Sobre IBD

Ropa naftowa jest wydobywana w postaci emulsji A/O, w której woda ze zbiornika i/lub metod odzyskiwania jest rozproszona w postaci kropelek w ciągłym medium oleistym. Wytworzona woda musi zostać usunięta z oleju, ponieważ nie tylko nie ma wartości ekonomicznej, ale generuje koszty operacyjne. Jednak emulsja olejowa może mieć wysoką stabilność kinetyczną ze względu na obecność substancji amfifilowych naturalnie obecnych w oleju, takich jak asfalteny i żywice, co utrudnia oddzielenie wody od oleju. Emulsje można destabilizować za pomocą procesów fizycznych i/lub chemicznych, w tym przy użyciu środków powierzchniowo czynnych. Niniejsza książka zawiera dogłębny przegląd najnowszych prac nad chemiczną demulgacją oleju, oceniając warunki procesu i właściwości środków powierzchniowo czynnych pod kątem skuteczności oddzielania wody od oleju. Obejmuje również ważne koncepcje dotyczące struktury emulsji i środków powierzchniowo czynnych oraz mechanizmów stabilizacji i destabilizacji emulsji.

  • Oil Emulsions
    César Augusto Sodré da Silva / Cleiton de Souza Beraldo / Rejane de Castro Santana
    Oil is produced in the form of an A/O emulsion, where water from the reservoir and/or recovery methods is dispersed as droplets in the continuous oily medium. The water produced needs to be removed from the oil, because as well as having no economic value, it generates operating costs. However, the oil emulsion can have high kinetic stability due to the presence of amphiphilic ...
