Short path and wiped film distillation combined in one technology

Combining short path and wiped film distillation methods can provide you with a more flexible approach on achieving your desired product quality. In multi-stage systems, complex product mixtures can be separated in the individual fractions with the desired quality. The multistage pilot plant distillation system by VTA can be configured based your particular requirement.

The VTA pilot multistage distillation units are suitable for generating scalable data for industrial system, producing certain sample quantities and optimization of existing process like concentration, fractionation, distillation, purification and drying of heat sensitive and high-boiling products.

Modular short path distillation units that will enable a later scale up to industrial systems

With short path distillation, a substantial decrease of boiling temperature is obtained by reducing the operating pressure. The VTA Pilot short path distillers are set up as modules and used to separate small product quantities that will enable a later scale up to industrial systems. The evaporator has an achievable operating pressure down to 0.001mbar. It can process a material with a maximum viscosity of 15,000 mPas (cP) at operating temperature.

Small scale thermal separation with short path distillation

With short path distillation, a substantial decrease of boiling temperature is obtained by reducing the operating pressure. The VTA Laboratory short path distillers integrate the short path distillation technique and are set-up as modules.

The fabrication of the unit’s main components enables observation of the product properties for foaming or potential fouling during distillation contributing to additional data for analysis.

Evaporation at low operating pressure with very gentle distillation

The special design of short path evaporators by VTA allows operating pressures down to 0.001 mbar. The very low operating pressures ensure very low distillation temperatures and therefore a very gentle distillation is possible. The short path distillation allows the thermal separation of high molecular and high-boiling products.

Thanks to short residence time, low evaporation temperature and the immediate cooling of the concentrate, thermal stress and decomposition of the product can be minimized.

Suitable for concentration, fractionation, distillation, purification and drying of heat sensitive products and high boiling point components.
