 Versatile Fractionation Column with Vapourization Under Forced   Circulation

FUNCTION

To fractionally distil heat sensitive multi-component mixtures under highly controlled heating conditions whilst maintaining a constant ratio of quantity of liquid to area of heating.

CAPACITY

 30 Litres To 20,000 Litres

SALIENT FEATURES

Falling film type of heat exchanger provided at the reboiler with a totally leak proof pump with mechanical seal ensures high heat transfer coefficient and facilitates vaporisation of the liquid maintaining minimum temperature differential  between the source heat and the boiling point of the liquid at the operating pressure. This minimises thermal impact to the liquid and also prevents localised heating. Thus heat sensitive materials can be handled very safely in this column. All the joints are carefully machined. PTFE gaskets provided between all flanged joints ensure leak proof system. This facilitates fractionation at high vacuum.  A highly efficient structured packing with distributors ensures low HETP and low pressure drop.

The automatic / pneumatic reflux distribution system provided with control panel allows for programmed reflux distribution. This facilitates better control on the entire system and the quality of the performance of the column. The entire system is provided with flameproof fixtures. The energy meter provided at the panel gives the total energy consumption after a batch  is worked out. Only one operator can operate the column efficiently.  Vacuum /  vapour  traps and manifold system facilitates operating the column at selective vacuum at different lines  without disturbing the column  equilibrium. View glasses provided at various locations to have visual control on the system. The entire system is placed on a bolted steel frame, which can be assembled and dismantled quickly. The system is provided with an in-built heating / cooling system and control valves and electrical control panel. Vacuum pump and traps can be provided on request.

 Batch Fractional Distillation Unit

FUNCTION

To fractionally distil multi-component mixtures under atmospheric pressure as well as under  reduced pressures with high efficiency.

CAPACITY

50 Litres to 5000 Litres Reboiler with 5 to 30 theoretical stages.

SALIENT FEATURES

The reboiler is provided with a mechanical agitator to accomplish uniform boil up of the mixture without localised heating and hence avoiding thermal shocks. Controlled heating facility ensures fairly uniform boil-up rates and avoids over heating. Highly efficient structured packing provides a low HETP and low-pressure drop across the column. The unique reflux distribution system with control panel and adjustable program ensures high efficiency of separation. The design of condenser ensures low-pressure drop across it. The appropriate design of the sub cooler ensures the entire material to be sub cooled to the desired temperature before it is withdrawn. The vacating facility provided ensures easy removal of the distillate without disturbing the vacuum of the system. The vacuum manifold provides a unique feature where the column can be switched over to any vacuum pump at any time. Adequate vapour traps provided to ensure complete trapping of the uncondensed vapours  thereby preventing the vapours from entering the vacuum pumps.

 Octagonal Blender

Chemac is best known for its mixers, blenders, dryers and mills. In recent years the company has also built a national reputation for its CUSTOM FABRICATION operations. The company offers complete design, instrumental and fabrication for any application with a great efficiency. The company is a group of chemical engineers, mechanical engineers, chemists & process engineers.

Chemac blenders are used for simple dry blends to complex vacuum drying operations.

The Octagonal Blender units are high quality products incorporating the latest technology in the Blender design with consistent quality control ensuring high efficiency and proven durability. Our Blenders deliver reliable trouble free maintenance and service. The blender is unexcelled for rapid, homogeneous blending of dry and semi dry products.

Octagonal Blender is ideal for blending the most delicate and fragile products; it is also the best way to mix very heavy and abrasive products. The range of products being successfully mixed includes colors, plastics, flour, drugs, pharmaceuticals, metal powders, minerals, fibers and many others.

Hygienic and easy to clean, each blender has unique multi shear baffle for improved blending efficiency of free-flowing powder and granules.

To operate, it is revolved end over end, moving the materials in & out of the constricted octagonal areas. This causes multiple folding actions that ensure a thorough inter-meshing of all the ingredients in the batch. The result is a homogeneous blend regardless of particle size distribution, particle shape or density.

The blender design ensures that there are no dead pockets of unmixed products. For successful blending, the ingredients must be free flowing and discharge readily from the upright static blending chamber.
