Significance and Use | ||||||||||||||||
Vapor pressure of crude oil at various V/Ls is an important physical property for shipping and storage. Note 2—A vapor-liquid ratio of 0.02:1 (X = 0.02) mimics closely the situation of an oil tanker. Vapor pressure of crude oil is important to crude oil producers and refiners for general handling and initial refinery treatment. The vapor pressure determined by this test method at a vapor-liquid ratio of 4:1 (VPCR4) of crude oil at 37.8°C can be related to the vapor pressure value determined on the same material when tested by Test Method D323 (see Appendix X1). Chilling and air saturation of the sample prior to the vapor pressure measurement is not required. This test method can be applied in online applications in which an air saturation procedure prior to the measurement cannot be performed. |

1. Scope | ||||||||||||||||
1.1 This test method covers the use of automated vapor pressure instruments to determine the vapor pressure exerted in vacuum of crude oils. This test method is suitable for testing samples that exert a vapor pressure between 25 and 180 kPa at 37.8°C at vapor-liquid ratios from 4:1 to 0.02:1 (X = 4 to 0.02). Note 1—This test method is suitable for the determination of the vapor pressure of crude oils at temperatures from 0 to 100°C and pressures up to 500 kPa, but the precision and bias statements (see Section 14) may not be applicable. 1.2 This test method allows the determination of vapor pressure for crude oil samples having pour points above 0°C. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 7.2.1-7.3.2. |
