Abstract The ability to accurately model and simulate chemical processes has been paramount the growing success efficiency in process design operation. These improvements usually come with increasing complexity of underlying models leading substantial computational effort their use. It may also occur that structure is sometimes unknown making optimization study difficult. To circumvent these issues, mathematically simpler models, commonly known as surrogate have designed used successfully...
Life cycle of an ideal green solvent from cradle to grave for sustainability studies solvents.
Although ionic liquids (ILs) have been widely explored as solvents for extractive desulfurization (EDS) of fuel oils, systematic studying the optimal design ILs this process is still scarce. The UNIFAC‐IL model extended first to describe EDS system based on exhaustive experimental data. Then, obtained and group contribution models predicting melting point viscosity ILs, a mixed‐integer nonlinear programming (MINLP) problem formulated purpose computer‐aided liquid (CAILD). MINLP solved...
Enzymatic fuel cells convert the chemical energy of biofuels into electrical energy. Unlike traditional cell types, which are mainly based on metal catalysts, enzymatic employ enzymes as catalysts. This type can be used an implantable power source for a variety medical devices in modern medicine to administer drugs, treat ailments and monitor bodily functions. Some advantages comparison conventional include simple design lower cost main components, however they suffer from severe kinetic...
To properly screen and use ionic liquids (ILs) as environmental-friendly solvents in chemical reactors separation processes, the knowledge of their solubilities with water is essential. In present work, mutual 1500 ILs (50 cations, 30 anions) at 298.15 K were predicted by using conductor-like screening model for real (COSMO-RS) a thermodynamic model. On basis COSMO-RS calculations, influence types anion cation, side chain modifications substituent groups on solubility was extensively...
