By the example of reversible parallel and consecutive reactions the possibility of using reagents and side products recycling in order to obtain high conversion and selectivity values was investigate.

The influence of recycled flow operation on the value of minimum energy consumption for total conversion of A reagent to B product was studied with A↔B reaction as an example.

On example of A⇔B reaction the influence of hydrodynamic condition in the reactor on recycle flow rate need for determined conversion value is investigated. The continuous stirred tank and plug flow reactors considered.

The mathematical model for system, containing ethanol, chloroform and 1-ethyl-3-methylimidazoliumtrifluorosulphonate is obtained. NRTL binary parametres are evaluated and vapor-liquid equilibrium is calculated. The possibility of separation ethanol-chloroform mixture with ionic liquid as extractive...

The mathematical model of a recycled flow sheet is studied. The number of degrees of freedom is determined, and different sets of the simulation task are considered. Analytical and numerical calculation of the recycled flow sheet steady states is performed.

On example of the А+В↔С reaction which is situated in zeotropic mixture the different variants of separation unit design are suggested. Presented separation unit includes both two simple distillation columns and one side stream column. The separation unit allows obtaining high values of reagents con...
