Analysis and optimization of exergy losses in a heavy water distillation column
Abstract: Heavy water (D2O) of isotopic purity 99.9% and more is used as the moderator and the coolant in pressurized heavy water nuclear reactors (PHWRs). This purity is maintained by vacuum distillation. In the column there are various sources of irreversibility and thermodynamic inefficiency. This work presents an analysis of these losses in a typical heavy water distillation column and their dependence on various design and operating parameters of the column. …

UNIT OPERATIONS IN CHEMICAL INDUSTRIES
Abstract: The unit operation like distillation, absorption, evaporation, filtration, drying, etc. are most important factors. Distillation is a purification method for liquids and can separate components of a mixture if they have significantly different boiling points. Absorption is a physical or chemical phenomenon. Evaporation can be defined as the process where liquid is transformed into a gaseous state. Evaporation can occur only when water is available. Drying is an important unit …

Nanocoating and Electrospraying Techniques Used for Corrosion Mitigation of Aluminum in Nitrogen dioxide Environment
Abstract: Nitrogen gas absorbs moist air to produce nitric acid. It develops acidic medium for aluminum. It forms a corrosion cell on the surface of aluminum. The formation of corrosion cell is written as: Al|Al+3||H+|H2 thus Corrosion reactions accelerate on aluminum surface and Al is oxidized into Al+3 and the H+ ions is reduced into H2. This acid produces various forms of corrosion in aluminum like galvanic, pitting, stress, crevice, blistering, …

Review Paper on Solid Waste Management in India
Abstract: Solid waste management is a major problem in urban areas of India. It is due to large urbanization, industrialization, and increasing population. The solid waste management systems ranked very poorly in India over the last few decades. Approximately 90% of residual waste is dumped instead of its proper landfilling. The solid waste management system should be improved in India because it will be beneficial for our future generations and the …

Elucidation of Synthetic Mechanism Involved in the Conversion of Zwitterionic Clonixin to Carboxamide Side-Product
Abstract: N-(3-Chloro-2-methylphenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide is obtained as a by-product during the synthesis and crystallization of Clonixin (2-(3-chloro-2-methylanilino)nicotinic acid) and its polymorphs, respectively. This conversion was unexpected and it changed the usual investigation path way enabling the formation of neutral and zwitterionic polymorphs in our study on Clonixin in contrary to studies of 2-(p-tolylamino) nicotinic acid investigation. The same conversion is checked in the other synthesized analogs such as 2-(phenylamino)nicotinic acid (PNA), 2-(methyl(phenyl)amino)nicotinic acid …
