Use of Advanced (i.e., Membrane) Technology for the Wastewater Treatment of Coke Ovens
Abstract: Coke plants produce gas, and coke for metallurgical purposes and also supply the raw materials for the manufacture of dyes, drugs, and high explosives. Naturally found coal is converted into coke in coke ovens. A large quantity of water is used for quenching hot coke and for washing gas. After quenching the wastewater contains high-suspended solids, high biochemical oxygen demand (BOD) (600–1300 mg/L), chemical oxygen demand (COD) (1500–3000mg/L), phenols(500–650 mg/L), …

pH-Responsive Smart Polymer Nanocomposites for Anti-Corrosive Coatings
Abstract: Metallic corrosion under adverse marine and industrial conditions imposes gigantic financial burdens and risks worldwide. Conventional waterproofing waterborne epoxy has passive barrier protection, but is also inherently microporous, lacking intrinsic repair ability against mechanical damage and thus rapidly decays. This is a critical gap that this work tries to bridge by designing a new pH-responsive hybrid polymer nanocomposite by using polyethyleneimine-tannic acid-cerium functionalized boron nitrate nanosheets with chitosan-capped mesoporous silica …

Optimization of Type-4 Plastic Liner Composite Overwrapped Pressure Vessel Design
Abstract: Composite Overwrapped Pressure Vessels (COPVs) are prominently utilized for the storage of gases at high-pressure. Their widespread adoption is because they are significantly lighter weight compared to complete metal counterparts, but requires specialized design, and manufacturing process. This research employs finite element modelling to analyse the stress and failure assessments on a specific Type-IV COPV with plastic liner as core cylinder. This study aims to optimize COPV design by considering …
