Item Removal and Recovery of Surfactants by Foam Fractionation(2022) Kumar, Awadh KishorSurfactants are used in many industries, and they are integrally related to many consumer products. However, at the same time, they contaminate water. The environmental fate of the surfactants is considerably important due to their effects on the health of human beings and animals. They are of interest because of their increasingly ubiquitous domestic and industrial use, and the difficulty in removing them by the traditional treatment methods. The removal of of different types of surfactant by foam fractionation has been practiced for water/wastewater treatment. This process and its applications in water/wastewater treatment have been discussed in the Chapter 1 of this thesis. Chapter 2 of this thesis focuses on the materials and experimental methodsItem Synthesis and Performance Evaluation of a Novel Natural Surfactant–Polymer Assembly for Enhanced Oil Recovery(2022) Machale, Jinesh SubhashA significant amount of oil (i.e., 60–70%) remains trapped in the reservoirs after the conventional primary and secondary methods of oil recovery. Enhanced oil recovery (EOR) is, therefore, necessary to recover the major fraction of unrecovered trapped oil from the reservoir to meet the present-day energy demands. The chemical method of EOR involves the injection of alkali, surfactant, polymer, and a combination of alkali–surfactant–polymer solution in the reservoir with the objective of achieving a reduction in interfacial tension and matching the mobility between oil and water for more recovery of oil. The success of this method depends on the effective synergy between the chemical additives.
