Analysis of heavy oils: Method development and application to Cerro Negro heavy petroleum: Distillation and determination of routine chemical/physical properties: Topical report
Part A discusses distillation of Cerro Negro heavy oil and general chemical/physical properties determined on each distillate and the residue. Based on GC-simulated distillation results, compounds boiling up to 700/degree/C atmospheric equivalent boiling point (AEBP) were distilled; nevertheless, total distillate yield represented only 55 weight percent of the whole crude. As revealed by comparative data on other crudes contained in the report, overall, chemical/physical properties of Cerro Negro crudes resemble those of tar sand bitumens and other geochemically related organic matter. Part B examines methodology for determining average molecular weights of Cerro Negro fractions and like materials. The theory and practice of vapor pressure osmometry (VPO) as applied to fossil fuels was critically evaluated through its application to Cerro Negro fractions and pure compounds, and by comparison of VPO results to those from other methods. Both solute-solute and solute-solvent intermolecular associations cause VPO data to be erroneously high, especially in cases where either the solutes and/or solvents are relatively polar. 79 refs., 24 figs., 6 tabs.
