Crude Oil Analysis & Evaluations
PRI provides crude oil analysis and evaluations with a strong focus on Resids / VTB’s and related cuts.

PRI maintains atmospheric and vacuum distillation apparatuses to provide sufficient Resid / VTB to conduct full characterizations for paving, roofing or industrial use.

PRI provides experience and background in evaluating an array of crudes, crude blends and/or back blending with VGO’s to produce articles of commerce.

Crude analysis and distillation provides the first step in the complete characterization of the Resid / VTB for use as product and/or feed stock for coking.

Coupled with PRI’s value added oxidation, emulsification, polymer blending and / or related engineering approaches and downstream evaluation and assessments crudes may be fully characterized for commercial value optimization in assorted markets.
