Vapor Pressure
Vapor Pressure
(OP)
Howdy all,
I need to find the Vapor Pressure of VGO 100-120 Deg F, Asphalt 300-350 Deg F, and MCB 200 Deg F. I understand about their characteristics I have just hit a wall with the vapor pressure. Would anyone be able to point me in the right direction for a website or source that is credible? Thanks for all of the help.

The general idea is that both LVGO and asphalt, as obtained from a vacuum tower, should have very low vapor pressures at those temperatures, especially if they did not suffer any thermal cracking.
As for the MCB, if it means Medium Curing Bitumen, it all depends on the kerosine flux properties.
If the VGO vacuum tower withdrawal was done at 10 mm Hg and 450 deg F and the bitumen's was at 750 deg F and 25 mm Hg, both vapor pressures would be well below 0.1 psia at the given temperatures. Which corroborates JLSeagull's message.
