发明名称 COMPOSICAO DE MATERIA E PROCESSO PARA REMOCAO DE PO DE CRUS DE PETROLEO PESADO INTEGRAL NAO CONVENCIONAL FRACOES DE CRU DE PETROLEO PESADO E RESIDUOS CRUS SINTETICOS E FRACOES DE CRUS SINTETICOS QUE CONTEM SOLIDOS FINAMENTE DIVIDIDOS
摘要 <p>Finely divided particulate solids are removed from unconventional whole heavy petroleum crudes, heavy petroleum crude fractions, and residua, syncrudes and syncrude fractions, particularly shale oil and shale oil fractions, by the use of novel surface active agents characterized as an admixture of (I) a surfactant comprised of (A) an ethoxylated or propoxylated ester, or ester constituted or a 1,4-sorbitan skeleton to which at least one and up to three ethoxy, propoxy, or mixed ethoxy-propoxy, and at least one and up to three fatty acid substituents are attached through oxygen to the 2,3,5 and 6 carbon atoms; and preferably this compound (A), or mixture thereof, is further admixed with (B) an organo sulfonic acid and more preferably (I) is admixed with (II) a demulsifier which is characterized as an ethoxylated, propoxylated, or mixed ethoxylated/propoxylated phenol formaldehyde resin substituted at a position para to said ethoxy and/or propoxy group, or groups, with a hydrocarbyl group.</p>
