Compatibility Assessment of Crude Oil Blends Using Different Methods
Chemical Engineering Transactions, 2017 Today, opportunity crude oils and their blends have attracted the attention of oil companies looking to increase their cross refinery margin. However, when crude oils are blended in the wrong proportions or even the wrong order, they can precipitate ...

From Problematic Asphaltenes towards Hyper-crosslinked Polymeric Structures
, 2023 The nanoaggregate formation of asphaltenes, the heaviest component of crude oil, is an important scientific challenge. The nanoaggregates of asphaltenes show polymeric behavior in solution, allowing the determination of average molecular mass by ...

Journal of Surfactants and Detergents, EarlyView.Materials and main results of the study. ABSTRACT Surfactant–polymer (SP) flooding is a promising Enhanced Oil Recovery (EOR) technique, combining improved displacement from surfactants with enhanced sweep efficiency from polymers. This study investigates two SP systems based on the biopolymer scleroxanthan (a blend of sclerotium gum and xanthan gum ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...

A New Approach to Determine Asphaltenes Stability
, 2017 Asphaltenes stability is a phase behavior phenomenon and affected mainly by the change in pressure and temperature. However, the changes in pressure and temperature lead compositional changes, hence, the dependency of asphaltenes stability on crude oil ...

Polymer Engineering &Science, EarlyView.Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...
