Fines deposition during hydrotreating: Effects of catalyst size and bed arrangement

The Canadian Journal of Chemical Engineering, Volume 103, Issue 9, Page 4390-4401, September 2025.
Abstract Fines deposition presents a significant problem during the hydrotreating of bitumen‐derived gas oils. The accumulation of fines leads to reactor clogging and consequently, pressure drop buildup. At critical levels, the hydrotreating reactor must be prematurely shutdown, resulting in substantial economic losses for refineries.

Organic alkalis as potential additives in hot water flooding for enhancing heavy oil recovery

The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3955-3970, August 2025.
Abstract Alkali–surfactant–polymer (ASP) flooding is a chemical enhanced oil recovery method; its working mechanisms include mobility control, wettability alteration, and in‐situ emulsification. However, conventional alkalis used in the ASP flooding could cause some serious issues, including scaling, formation damage, and pipe corrosion. In this study,

Enhancing asphaltene precipitation modeling by cubic-PR solid model using thermodynamic correlations and averaging techniques

Petroleum Science, 2019
Cubic equation-of-state solid models are one of the most widely used models to predict asphaltene precipitation behavior. Thermodynamic parameters are needed to model precipitation under different pressures and temperatures and are usually obtained ...

Practical aspects of multiphase slug frequency: An overview

The Canadian Journal of Chemical Engineering, Volume 103, Issue 6, Page 2880-2894, June 2025.
Abstract Slug frequency, the number of liquid slugs passing through a point per unit of time, is an intrinsic parameter that is used to characterize multiphase slug flows in pipes. In this review we discuss practical aspects of slug frequency for industrial purposes from an examination of published literature and available experimental data. The review

Hydrophobically Modified Chitosan‐Based Polymers for Enhanced Oil Recovery

CleanMat, Volume 2, Issue 2, Page 167-182, June 2025.
Conversion of biowaste (shrimp shells) into high value product for upstream applications. ABSTRACT The upstream petroleum industry significantly contributes to environmental pollution through the use of fossil‐derived chemicals. This study explores the potential of green alternatives by synthesizing and evaluating chitosan‐based polymers for enhanced ...
