Korea Institute of Civil Engineering and Building Technology (KICT) has introduced a groundbreaking vapor pressure equation. This innovative study addresses the limitations of the Lee-Kesler ...

The vapor pressure process analyzer includes the ASTM D6377 method, which is considered the latest standard for determining the vapor pressure of crude oil without any need for sample preparation.

Equation 1 is in terms of the vapor pressure at a reduced temperature of 0.7 and the critical pressure. P r s = P s /P c , and is known as the reduced vapor pressure.
