A) Batch Type Distillation
UNI-MECH has hand on experience to manufacture Vessels & Columns from almost all material of constructions, used in process Plant industries.
The columns are mass transfer units generally used forthe following applications :
- Solvent Extraction
- Gas Absorption
- Packed Column etc
Columns of various sizes and capacities are manufactured by Uni-Mech with complex internals like single pass perforated trays/double pass perforated trays with TSR (Tray Support Rings) and bolting bars.
Uni-Mech are manufactured even for critical fluids like Ammonia, Nitrogen, Hydrogen, High Pressure Air, etc.
Uni-Mech Columns are made from suitable materials like mild steel, different grades of stainless steel, hastelloy, duplex steel, titanium, etc.
- Shell: Diameter 300 mm to 5000 mm
- Height: Up to 50 Meters
- Thickness: 5 mm to 40 mm
- Design Code: ASME Sec-VIII, Div-1, IS-2825, BS-550
B) Continuous Type Distillation
Uni-Mech designs and supplies fractional distillation System for various aromatic chemicals, fine chemicals, and solvent recovery. The company’s unique design offers high purity and maximum recovery of the product. Uni-Mech also designs systems for heat sensitive chemicals.
Continuous Distillation System
High Vacuum Distillation system is designed for separation of heat -sensitive, high molecular weight or viscous material using structured packing and Falling film orforced circulation evaporator.
Continuous Azeotropic Distillation System
It is used for separation of Azeotropic compound using third component as an entertainer.
Continuous liquid-liquid Extraction System
It is extensively used in the chemical industries where separation by distillation is difficult or not possible because of close boiling point of two component. Continuous extraction needs less solvent and less man power compare to batch system.
- Proven and time tested technology for the separation involving very low specific gravity difference
- Highest recovery of the product from mother liquor
- Durable and Demands less maintenance
- Fine Chemicals
- Bulk Drugs
- Petro Chemicals
Crystallization is an important unit of operation for manufacturing wide range of chemicals, which are ideal for use in pharmaceutical and chemical industries.
The nature of a crystallization process is governed by both thermodynamic and kinetic factors, which can make it highly variable and difficult to control. Factors such as impurity level, mixing regime, vessel design, and cooling profile can have a major impact on the size, number, and shape of crystals produced. Crystal growth is a layer-by-layer process with less retention time. Crystallization equipment has been classified according to the means of suspending the growing product.
Cooling Crystallizers :
- Static Crystallizers
- Draft Tube Baffle Crystallizers
- Evaporative crystallizers
- Forced Circulation Crystallizers
- Freeze crystallizers
- Melt crystallizers
- Oslo Crystal Crystallizers
Multi Effective Evaporator
Uni-Mech Multi Effect Evaporators are the equipment in which steam from an outside source is condensed in the heating element of first effect. The boiling temperature at which the first effect operates is high enough so that the evaporated water can serve as the heating medium for second effect. The vapors so formed are then sent to a condenser if it is a double effect evaporator. The feed for the multi-effect type evaporator is generally transferred from one effect to another. This leads to the ultimate product concentration to reach the desired effect through the evaporator.
Uni-Mech offers many Evaporators like :
- Falling Film Evaporator
- Thin Film Evaporator
- Forced Circulation Evaporator
- Rising Film Evaporator
