Gamma-valerolactone (GVL) has been synthesized from biomass and can be used as a fuel additive, green solvent, in polymers. The production of nylon GVL attracted growing interest due to application extension. We developed an energy efficient economically viable approach for the synthesis DAs (Dimethyl adipate) esterification using ionic liquid Ru-catalyzed metathesis. A large-scale process simu...

The article presents results of thermodynamic analysis using a zero-dimensional mathematical models negative CO2 emission power plant. developed cycle plant allows the production electricity gasified sewage sludge as main fuel. can be achieved by use this type fuel which is already “zero-emissive” energy source. Together with carbon capture installation, there possibility to decrease below “zer...

A new simulation model for Hydrogen production is developed on the Aspen Plus platform. Designing, Analysis and Optimization of the Metal Chloride based cyclic process is done thereby calculating the energy, exergy and overall efficiency of the same using the simulation software. Kinetic and thermodynamic analysis of chemical reactions occurring in each equipment of the proposed model is done. ...

the understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. this paper reports a dynamic simulation study of the possible distillation columns sequences of dew pointing unit in the second phase of south pars gas refinery. in this unit, three columns are u...
