Crude Oil Vapor Pressure Testing at its best

ERAVAP Crude is the solution for crude oil vapor pressure testing. It is tuned for measuring live or dead crude according to ASTM D6377, IP481 and GOST 52340. It includes optimized CCQTA methods for low V/L ratios. Curve measurements cover a temperature range from -20 °C to 120 °C and a pressure range from 0 kPa to 1000 kPa with excellent precision and measuring stability.

Crude Oil Vapor Pressure Testing

Vapor pressure of crude oil is a key parameter when planning the transportation of crudes through different climate zones. When performing crude oil vapor pressure measurements one has to bear the actual ambient conditions during transportation in mind. Is the crude transported in rail cars the headspace is approximately 5% where as a floating roof-top tank has nearly no headspace at all. This is important since the vapor to liquid ratio (V/L) and the storage temperature are highly influencing the vapor pressure of crude. This is especially true for live crude oil which still contains high amounts of volatile light ends.
