Oil spill remediation and valorisation of oil soaked sorbent by hydrothermal liquefaction

Abstract

Significant environmental problems are brought about by oil spills, newlinewhich makes sustainable water treatment methods essential. Because of their newlineeffectiveness and compatibility with the environment, adsorption-based newlineremediation techniques have become increasingly attractive as solutions. The newlinesignificance of adsorption in mitigating oil spills is examined in this thesis, with newlineparticular attention to its use in oil water separation and valorisation to useful newlineproducts for a sustainable solution. newlineAdsorption process removes impurities from water by causing oil newlinemolecules to adhere to solid surfaces. High removal efficiency, cost effective newlinesolution, possibility of adsorbent regeneration and reuse are some of the benefits newlineof this approach. By using fewer synthetic components and employing more newlinebiobased resource improves the sustainability of adsorption-based remediation newlineeven further. newlineAdsorption in oil spill remediation needs careful consideration of newlinevarious parameters such as the nature of the oil spill, operational conditions, and newlinequality of the adsorbent. Adsorbent surface modification, process parameter newlineoptimisation, and integration of various enhanced treatment methods can improve newlinethe adsorption performance. Large-scale oil spills pose serious environmental newlineproblems that requires effective cleanup techniques. Separated oil and spent newlinesorbent make for secondary pollutants, it becomes important to device an newlineenvironmentally friendly and effective remediation method. Adsorption using newlinebiomass-derived adsorbent especially becomes more viable strategy along with a newlinevalorisation technique that converts these secondary pollutants to more useful newlineeconomically valuable products. All things considered, adsorption-based newlineremediation and valorisation provides for an environmentally safe circular newlineeconomy approach to lessen the effects of oil spills, underscoring the significance newlineof cutting-edge technology in attaining environmental sustainability. newline
