To maximise the profitability of a refinery, planners must be able to make fast, accurate and optimal decisions about crude feedstock selection, process runs and product mix while considering numerous other factors, such as changing market demands and price volatility.

The challenges of evaluating various crude feedstocks are compounded if a crude blend is to be evaluated. Inaccurate and partial crude assay information results in sub-optimal refinery business performance.

EQNX has joined hands with world leader Chevron, to bring the latest Assay information on worldwide crude oils, right at your door step. Chevron has a dedicated team of seasoned professionals and state-of-the-art equipment & facilities at Richmond, USA to generate new crude assay qualities, update crude quality data and perform assay validations. Reviews for completeness, consistency and vetting with end users is done prior to ensure the accuracy of the up-to-date assay database.

The Chevron Crude Assay Database includes more than 2800 assays for over 1000 unique crudes with over 60 chemical and physical properties. The Chevron Crude Assay Database is seamlessly integrated through Aspen Assay Manager with Aspen PIMS, Aspen HYSYS and Aspen Unified, providing an unparalleled capability for modelling crude distillation operations.

EQNX is Chevron’s Global reseller to sell and support their Crude Assay Database. Our experts are at hand to address and resolve any queries.

When accurate modelling of physical units in a refinery has been achieved, by combining the capabilities of the Aspen Assay Management System with the Chevron Assay, more accurate evaluations of crude purchase choices and plant operations can be achieved to a level previously unavailable.

Challenge Solution Benefits
  • Crude Assays are old and outdated
  • Partial list of properties of crude assay available
  • Assays for the crudes to be evaluated are not available

Adopt Chevron Crude Assay Database, which includes the capability to use the world’s most comprehensive, popular and respected crude assay library from Chevron. Along with Aspen Assay Management System, it provides users unparalleled capability for modelling crude distillation operations, more accurate evaluations of crude purchase choices and plant operations aligned to market demands.

  • It provides accurate evaluations of crude purchase choices including complex refinery configurations.
  • It predicts the variability of yields and properties of the distillation products containing hundreds of different crudes.

The crude characteristics not only change amongst various crudes, but also within the shipments of the same crude, which is a major problem for refinery models
