Agitated Thin Film Evaporator

An Agitated Thin Film Evaporator (ATFE), also known as Wiped Film Evaporator (WFE), consists of a jacketed shell precision machined from inside and a rotor having blades that maintain a close clearance from the shell.

A feed distributor at entry point distributes the liquid in a thin film on the heated wall. The high speed rotor further spreads and intensely agitates the film as it flows down.

The generated vapors flow countercurrently and get cleaned by an integrally mounted entrainment separator. The processing is completed in a few seconds.

‘Our high viscosity units can handle products with viscosities of several million centipoise!’

FEATURES

• Residence time of a few seconds with a narrow spread, an important feature for heat sensitive products• Required evaporation is achieved in a single pass, avoiding product recirculation and possible degradation• Scale formation on the heat transfer surface is avoided due to the intense agitation of the liquid film• Excellent turn down capability• Low product holdup, ideal for hazardous applications• Operating pressure as low as 1 mbar and operating temperature up to 400 °C• Special designs for clean room applications

APPLICATIONS

• Vacuum distillation of bulk drugs, intermediates, fine chemicals, glycols, used lubricating oils, fatty acids and their derivatives, rubber chemicals, amines and esters• Concentration of bulk drugs• Processing of oleoresins, enzymes, plant extracts, milk products, juices and sugars• Stripping of silicone oils, pesticides, plasticizers and monomers• Recovery of contaminated solvents and products from residues• Paraformaldehyde and high viscosity applications like stripping of polymer melts• Purification of biodiesel and recovery of glycerin

Each component is subjected to detailed mechanical investigation

Short Path Distillation Unit

A Short Path Distillation Unit (SPDU) is also called as Molecular Distillation Unit. It provides minimum pressure drop, permitting high vacuum operation up to 0.001 mbar.It is distinguished from a standard Agitated Thin Film Evaporator by an internally mounted condenser. The vapor generated on the heated surface travels a very short distance to reach the condenser surface, thus eliminating pressure drop.

The condensed distillate and concentrate are collected separately in the bottom section before they are taken out.

‘Operating vacuum as low as 0.001 mbar helps in distilling high boiling and heat sensitive products’

FEATURES

• Residence time of a few seconds• Required distillation achieved in a single pass• Enhanced vacuum can lower boiling point by 100 to 150°C, as compared to ATFE• Excellent for gently processing heat sensitive, high boiling products• Low product holdup• Excellent turndown capability• Low power requirement• Operating temperatures up to 400°C

APPLICATIONS

• High vacuum distillation of • Pharmaceuticals, bulk drugs, natural or synthetic vitamins, esters • Epoxy resins, plasticizers, and stabilizers • Fish oil, omega-3 fatty acids, fatty acid derivatives, glycerides, tocopherol and tocotrienols • Fine Chemicals, silicone oils, and higher alcohols• Re-refining of spent lube oil• Purification of natural and synthetic waxes• Product recovery from distillation column residues

Agitated Thin Film Dryer

An Agitated Thin Film Dryer (ATFD) has a centrally located rotor having closely fitting blades. It rotates in a precision-machined jacketed shell.The feed is converted into a thin film, which is intensely agitated due to action of the high-speed rotor. The feed material goes through phases of slurry, paste and wet powder, before coming out as a dry powder.We offer vertical, horizontal or combination dryers to take feed in solution, slurry, paste or wet powder form.

‘ The most energy efficient dryer in the market. Thermal efficiency exceeds 90% ’

FEATURES

APPLICATIONS

Drying • Pharmaceuticals, bulk drugs and intermediates• Dyes, pigments and intermediates• Organic and inorganic salts• Clean room applications• Possibility of amorphous powders

Recoveries • Solvents and products from residue • DMSO from salts• Glycerin from salts and residue • Organic solvents or products from salt bearing waste streams

Slurry, Cake, Distillate and Powder

Rising Film Evaporator

A Rising Film Evaporator (RFE) is a vertical shell and tube heat exchanger with a vapor – liquid separator mounted at the top.The liquid to be concentrated is fed at the bottom of the heated tube bundle. As it receives the heat, the vapors gener-ated lift the liquid upwards and push it on the wall as a film.The velocities generated by the vapor lift are quite high, giving good thermal performance. The balance liquid and vapor are separated in the vapor- liquid separator.

‘Simple solution for concentration of liquids that are moderately heat sensitive’

FEATURES

• Thermosiphon action due to boiling in vertical tubes eliminates the need for circulation pump • Multiple effect arrangement provides better steam economy • Trace quantities of suspended particles in the feed are tolerated

APPLICATIONS

Concentration of dilute solutions containing water and organic solvents in applications such as: • Plant extracts in water or organic solvents • As a reboiler to distillation column • Economical alternative to falling film evaporator for moderate vacuum and moderately heat sensitive products

Falling Film Evaporator

A Falling Film Evaporator (FFE) is a vertical shell and tube heat exchanger with a vapor- liquid separator mounted at the bottom.The liquid to be concentrated is fed at the top of the heated tubes and distributed in such a way that it flows down on the inside surface of the tubes as a thin film.As the film gets heated, the vapors generated flow co-currently. The drag of vapors increases the turbulence and improves heat transfer performance. The balance liquid and vapor are separated in the vapor- liquid separator.

‘Small holdup ensures quick response to changes in operating conditions, quick start-up and an easy switchover ’

FEATURES• Suitable for heat sensitive products• Multiple effect arrangement for better steam economy • Gentle evaporation, mostly under vacuum, with a short residence time in the evaporator

APPLICATIONS

Concentration of dilute solutions of heat sensitive products containing water or solvents in applications such as: • Plant extracts in water or organic solvents • As a reboilier to a distillation column • Recovery of solvents from contaminants • Purification of biodiesel

Reduced size of Agitated Thin Film Evaporatorwith volume reduction by tubular evaporation.

Plug Flow Crystallizer

Inside a Plug Flow Crystallizer (PFC), a shaft with uniquely arranged blades rotates within a shell. The product flows through in a nearly plug flow manner under uniform and gentle agitation. Multiple heating /cooling sections provide controlled temperature gradients and good control on primary nucleation. Gentle agitation minimizes secondary nucleation. Plug flow conditions provide uniform residence time, promoting narrow Crystal Size Distribution (CSD), which is important for improved purity and flowability.

‘The most scientifically designed continuous crystallizer ’

FEATURES

• Runs continuously • Can be used with high percentage of solids in slurries• Easy conversion from batch operation to continuous operation• Can also be used as a Scraped Surface Heat Exchanger for highly viscous products

APPLICATIONS

• Heating and cooling of heat sensitive, viscous products and particulate laden products• Continuous crystallization by cooling or evaporation • Dewaxing • Separation of isomers• Purification of organic intermediates

Narrow Crystal Size Distribution

Liquid- liquid Extraction Column

A Liquid- liquid Extraction Column (LLEC) is used as a continuous option to batch extraction in kettles. A liquid feed is contacted with an immiscible solvent that exhibits preferential affinity towards desired components.At the outlet, we get an extract enriched with the desired component and the raffinate, the spent feed, containing very little of the desired component.A continuous LLEC has a series of mixers and settlers that offer 4 to 6 equivalent stages of separation.

‘Up to 50% reduction in solvent usage and 70% reduction in power usage are possible’

FEATURES

• Improved and consistent results • Significant reduction in power, space and solvent loss• Continuous operation, no supervision required• Optimum design arrived at after simulation by Computational Fluid Dynamics (CFD) studies

APPLICATIONS

• Separation of close boiling components, which are otherwise difficult to separate by distillation • Breaking of azeotropes• COD, BOD reduction in wastewater • Purification of fine chemicals and pharmaceuticals• Change in pH by washing • Reactive extraction

CFD simulation for optimum results

Annular Centrifugal Extractor

An Annular Centrifugal Extractor (ACE) has a rotor basket spinning at a high speed. This promotes intensive mixing in the outside annular space where the two immiscible phases quickly reach an equilibrium.

The mixture enters the inner volume of the rotating basket where high centrifugal force quickly separates the two phases. The extract and raffinate are discharged through separate outlets.

’Small holdup makes it suitable for quick switchover with batch integrity’

FEATURES

• Liquids with low-density difference and emulsifying tendencies are successfully processed• Continuous operation, no supervision required• Quick switchover due to small holdup. Ideal for pharma application• Up to 50 – 70% reduction in solvent and power use• Requires less space • Consistent results • Very small holdup makes it ideal for hazardous applications

APPLICATIONS

Suppressed Boiling Evaporator

A Suppressed Boiling Evaporator(SBE), also called as Forced Circulation Evaporator (FCE), has a vertical shell and

tube heat exchanger as the calandria, a separator and a circulation pump for circulation of slurry though the tubes.

Good velocity in the tubes and adequate hydrostatic head suppresses boiling inside the tubes. Therefore, scaling on the

tube surface is minimized.

‘Thanks to our axial flow pump, Technoforce evaporators out-perform the competition when it comes to reduced scaling’

Axial Flow PumpThese pumps are designed for high flow against low head. They are used with a great advantage in closed loop circulation where the pump casing becomes merely an elbow in the circulation line.• Axial flow pumps deliver 5 times more flow as compared to centrifugal pumps using the same horsepower• The high efficiency impellers are developed using Computational Fluid Dynamics (CFD) simulation techniques and machined on a CNC machining center. The pump performance is validated on a test rig.

FEATURES

• Axial flow pump ensures high tube velocities with minimum power consumption• Carefully balanced flow and hydrostatic head truly suppress boiling and scaling in the tubes• Generously sized flash separator minimizes entrainment, resulting in a clear distillate

APPLICATIONS

• Preconcentration of scale prone liquids before drying • Multiple effect arrangement for reduction in the steam requirement• Wastewater concentration for volume reduction• Concentration of solution having organic and inorganic salts • Evaporative crystallization
