Distillation

New method to measure TAN of crude oil and refinery distillation fractions

Many refiners look at discounted opportunity crudes as a way to improve their margin spread. The growing varieties of discounted opportunity crudes on the market contain certain risks for the purchaser, such as high naphthenic acid or sulfur content.

Performance testing: The key to successful revamps

Lieberman, N., Process Improvement Engineering

Process unit revamps often do not result in a refiner achieving its desired objectives. This is typically not the result of mechanical defects with process equipment.

Neste Jacobs’ NAPCON selected for Borealis PE2 plant's distillation section

Technology, engineering and project management company Neste Jacobs was selected to optimize the recovery area of Borealis Borstar PE2 plant in Porvoo, Finland with Neste Jacobs' NAPCON Controller solution.
