... crude oils at high temperatures. As an example, consider the steam-distillation process. Depending on oil gravity, 15 to 30 vol% of oil could vaporize in the presence of steam at a pressure of approximately 500 psia and a temperature of 467°F In the absence of steam, there may be no vaporization...
