Distillation Control System ILUDEST® [DC / MoS]² - ILUDEST®‘s PC-based Control System for Fully Automated Operation

The iFischer® DIST D2892/5236 CC or FISCHER® AUTODEST® 800/860 AC is a fully computer controlled unit of turnkey design, and ready for use after installation and commissioning. Fully housed and equipped with doors in the front and rear to satisfy safety requirements and to facilitate service aspects. The automatic fraction collector (in the system section TBP with 20 receivers) includes a builtin internal balance for the determination of the fraction weight, while the separate volume follower system is used for discharging the fractions into the final receivers and the determination of the fraction volume as well as for the direct distillation rate control. The automatic fraction collector (in the system section Potstill with 12 receivers) includes a builtin internal balance, which is used for the simultaneous determination of the fraction weight and for the direct distillation rate control.

Automatic SemiMicroDistillationUnit with the FISCHER® SPALTROHR® Column Compact and especially versatile, the fully automated FISCHER® LABODEST® HMS 500 AC is a unit with highest separation efficiency A modular system, which can be designed according to specific requirements including an equipment for recording the distillation curve or for printingout the distillation record by means of a printer or for connection for electronic data processing.

Scientists and chemical engineers still measure phase equilibria despite the significant improvement in theoretical evaluations. Therefore, our phase equilibrium apparatus is part of the standard equipment in chemical engineering laboratories. The vapourliquid equilibrium of binary and multicomponent mixtures constitute an essential basis for the determination of the theoretical plates necessary for the evaluation of separation processes. Although VLEdata are known from literature, there is still an increasing tendency towards redetermining equilibrium data by experiments, because the thermodynamic parameters like pressure, temperature and concentrations are different or inadequate. For designing e.g. extractive distillation processes the evaluation of vapourliquidliquid phase equilibria (VLLEdata) are required. The practical measurement and determination of these data proves difficult with the standardised VLEunits because of the phase formation of the liquids.

Especially the theoretically additional evaluation of the temperature and pressure dependence of phase equilibrium is insufficient very often in daily practice, thus the experimental determination of VLEdata is increasingly requested in the overpressure range, too. ILUDEST®/ iFischer® modified the VLEequipment, since decades sold under the worldknown FISCHER® brand, suitable for the overpressure range up to 50 bar. The VLEequipment is designed for a charge of 50 ml (dynamic mode) and can be operated under vacuum (1...1,013 mbar), atmcondition and overpressure (1...50 bar) as well as temperature up to 250°C. An extended operating range up to 100 bar is possible.
