PrintCrude Assay
Crude oil assay consists of a compilation of data on properties and composition of crude oils. The assay provides critical information on the suitability of crude oil for a particular refinery and estimating the desired product yields and quality. It also indicates how extensively a given crude oil should be treated in a refinery to produce fuels that are in compliance with environmental regulations. A typical crude assay should include the following major specifications:
- API Gravity
- Total Sulfur (% wt)
- Pour Point (°C)
- Viscosity @ 20°C (cSt)
- Viscosity @ 40°C (cSt)
- Nickel (ppm)
- Vanadium (ppm)
- Total Nitrogen (ppm)
- Total Acid Number (mgKOH/g)
- Distillation Data
- Characterization factor KUOP, KW
