The environmental problem stemming from toxic and recalcitrant naphthenic acids (NAs) present in effluents the oil industry is well characterized. However, despite numerous technologies evaluated for their destruction, up-scaling potential remains low due to high implementation running costs. Catalysts can help cutting costs by achieving more efficient reactions with shorter operating times low...

This work assesses the effect of adding CaO during pyrolysis waste tires (WT) using a twin-auger reactor on properties derived products. Pyrolysis was conducted in lab-scale facility at temperature 475 °C, solid residence time 3.5 min, WT mass flow rate 1.16 kg/h, and N2 300 mL/min. continuously fed ratios 10, 15, 20 wt %, according to rate, two particle size ranges: fine (105–149 μm) coarse (1...

The objective of this study is to discover a synergistic effect between foam stability in bulk and micro-emulsion phase behaviour to design a high-performance chemical system for an optimized alkaline-surfactant-foam (ASF) flooding for enhanced oil recovery (EOR). The focus is on the interaction of ASF chemical agents with oil in the presence and absence of a naphthenic acid component and in si...
