WebHeavy oils display a high content of high mo- lecular weight hydrocarbons and elevated levels of heterocompounds including sulfur, nitrogen, oxygen and metals (Speight, 1991). Typically, the molecules present in heavy oil have more than fifteen carbon atoms in the chain, making the refining process more complex and costly (Trevisan et al., 2006). Web22 de jun. de 2004 · The flue gases also became near-miscible with the oil at elevated pressures, an indication that high pressure flue gas (or air) injection is a cost-effective process for enhanced recovery of light oils, compared to rich gas or water injection, with the potential of sequestering carbon dioxide, a greenhouse gas.
