Standard Test Method for Determination of the Asphaltene Solvency Properties of Bitumen, Crude Oil, Condensate and/or Related Products for the Purpose of Calculating Stability, Compatibility for Blending, Fouling, and Processibility (Manual Microscopy Method)

Importancia y uso:

5.1 Understanding the stability and compatibility of a petroleum product (crude oil or refinery stream, or both) is critical to facilities that receive multiple types of products and perform blending and processing operations. Blending incompatible streams can cause asphaltene precipitation with potential consequences such as but not limited to: refinery unit fouling, processing problems, throughput reduction, emulsion stabilization, pipeline and tank deposition, and equipment fouling.

5.2 The ability to predict the results of blending operations allows operators to anticipate potential problems and mitigate those problems prior to receiving the products. It also helps facilities to manage their product movements in the most effective manner to avoid future issues.

5.3 Some petroleum products are unstable without blending and understanding the stability of a product in terms of asphaltene precipitation is an important factor in product selection for refining. Products with poor stability can contribute to refinery unit fouling as well as the overall processibility and yield of that product.
