Purification is the removal of contaminating substances and by-products to increase the level of purity of the desired substance. Considerations for choosing a suitable purification system in the industry, include the physical state of the mixture, the desired product, required level of purity, the type of mixture, heat sensitivity of the product, number of purification steps needed, and the production volume. Industrial purification systems are used for the production of pure water in the food pharmaceutical and biotech industries.

Purification

Rose oil is an essential oil extracted from the petals of either Rosa damascena and Rosa centifolia. Also known as liquid gold, rose oil production originated from Greece and is currently manufactured mainly in Bulgaria, Turkey, and Morocco. Studies have shown that rose oil has medicinal properties, exhibiting anti-inflammatory, anti-infective, and wound healing actions.

With wiped film distillation, a substantial decrease of boiling temperature is obtained by reducing the operating pressure. It is a continuous process with very short residence time.


<h2>Separate high-boiling and highly viscous materials in a wiped film evaporator</h2>
The VTA wiped film evaporator has a rotating wiper system which speeds up the evaporation process by keeping the product film turbulent so that the heat transfer and mass transfer are optimized.

The residence time of the product at the evaporator wall is very short and the vapours are condensed on an external condenser.

It is ideal for separation, drying, concentration, fractionation, distillation, deodorization and purification of materials which have high boiling points and high viscosity.

Wiped film evaporator

Get to reliable conclusions for the separation of high-boiling and heat-sensitive products using as little as 2 kg of crude material.


<h2>Small scale thermal separation with short path distillation</h2>
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.

The VTA Laboratory short path distiller is suitable for feasibility studies, doing first process development steps, producing small sample amounts of final product and optimizing existing processes like concentration, fractionation, distillation, purification and drying of heat sensitive products and high boiling point components.

Laboratory short path distiller

A laboratory multi-stage distillers that combines the wiped film and short path distillation technique allows you to test the separation of high-boiling, heat sensitive and highly viscous products by just using a small amount of material.


<h2>Short path distillation and wiped film distillation in one technology</h2>
The VTA Laboratory multi-stage distillers are a combination of short path and wiped film distillation technique. It is recommended to equip such systems with continuous feed and discharge pumps to have a smooth and simple operation.

The VTA Laboratory multi-stage distillers can be configured based on customer’s requirement.

It is suitable for feasibility studies, doing first process development steps, producing small sample amounts of final product and optimizing existing processes such as concentration, fractionation, distillation, purification and drying of heat sensitive products and high-boiling products.

Laboratory multi-stage distiller

Generate scalable data and results during the pilot tests with short path distillation, distill or dry of small product quantities with as little as 30 kg of crude material.


<h2>Modular short path distillation units that will enable a later scale up to industrial systems</h2>
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.

The VTA Pilot short path distillers are suitable for generating scalable data for industrial systems, producing certain sample quantities and optimization of existing process like concentration, fractionation, distillation, purification and drying.
