Study on the Corrosion of Carbon Steel in Gasoil-Brine Mixture in presence of acid

مجلة النهرين للعلوم الهندسية, 2017
Corrosion tests of carbon steel in two phase flow of two immiscible liquids (CaCO3 solution-gasoil mixture) under different operating conditions of temperature, agitation velocity, and phase fractions, were carried out using weigh loss method. Flat blade

Scale‐Down Platforms for Process‐Oriented Enzyme Screening Using Microfluidics

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Enzyme screening platforms are typically evaluated based on their throughput and analytical performance rather than their ability to mimic the conditions encountered at large scale. In bioreactors, enzymes experience gradients in substrate concentration, oxygen availability, pH, temperature, and interfacial exposure, caused by imperfect mixing

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Integrated numerical simulation and source‐sink matching methodology for Basin‐Wide CO2 storage assessment in depleted reservoirs: A Cambay Basin case study

Deep Underground Science and Engineering, EarlyView.
This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.
