Scope: This document specifies a method for determining the vapor pressure of crude oil using an automatic vapor pressure tester. This document is applicable to crude oil with a test temperature of 37.8 ℃, a gas-liquid ratio of 4:1, and a vapor pressure of 25kPa~180kPa. This document is also applicable to crude oil with a test temperature of 0 ℃ ~ 100 ℃, a gas-liquid ratio of 0.02:1 ~ 4:1, and a vapor pressure of 500kPa, but the precision may not be applicable.
