Resumen
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) In this work, an atmospheric petroleum residue was fractionated using a falling film molecular distillation pilot plant with molecular distillation temperatures ranging from 190 to 320 degrees C. The process produced four distillate cuts and four residues that were characterized in order to evaluate the efficiency of the technique. The results showed a gain of 11.7% in distillate yield in the highest molecular distillation temperature studied. Physicochemical characterization of the fractions demonstrated that complex compounds were separated of the distillate cuts and were concentrated in the residues which have compounds with features of resins and asphaltenes. Furthermore, data from molecular distillation experiments were used to extend the true boiling point curve of the crude oil up to 662 degrees C with continuity and good agreement with the ASTM curves. 52 44 15488 15493 CENPES/PETROBRAS Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)
