Jewellers worldwide and in India, have understood the many advantages of in-house refining and are appreciating the profits, by savings, otherwise not achieved due to low yields and/ or purity, idle storage of refinable gold, high refining charges, etc.

Precious Metal Refining Plant 1

Four simple steps to get pure Gold/Silver

Dissolution: Acids react with gold, silver, copper and other alloy constituents to form gold chloride solution, silver chloride precipitate and copper nitrate solution.

Filteration: Silver chloride precipitate and insoluble matter is separated from solution containing dissolved gold and copper.

Reduction: Gold reagent, added to solution, reduces gold chloride to pure gold oxide precipitate.

Washing: Gold oxide is removed from the remaining solution containing dissolved copper, is chemically washed and dried. You can now melt the gold powder and re-use as required.

Liquid extraction, sometimes called solvent extraction, it the separation of a liquid of a liquid solution by contact with another insoluble liquid. The Fully Automatic Solvent Extraction Plant described is for semi-batch operation.

Liquid-Liquid Extraction Unit (Solvent Extraction)

The liquid to be extracted is poured into extraction vessel. Solvent is boiled in a reboiler vessel and condensed in an overhead condensed, the condensed liquid in a reflux divider and passing through pipe work to the extraction vessel. The pipe work incorporates valve in order that the solvent can enter the extraction vessel at either the base of the top, depending on the relative density of the solvent and liquid to be extracted.

The solvent and the extracted liquid pass back to the reboiler and the process is reputed until the extraction is complete. The extraction vessel is than drained and the solvent evaporated from the reboiler vessel and collected in the extraction vessel enabling the two liquids to be drained from their respective vessel.

The Solvent Extraction Plant is available in vessel size upto 500 Ltr. and is suitable for operation under atmosphere pressure and vacuume. Today, we have carved a niche as one of the prime Modular Solvent Extraction Plant Exporters based in India.

Teaching units / Test Rigs are possible for various experiments to be performed in chemical engineering laboratories or R&D units pertaining to various processes like distillation, absorption, heat & mass transfer, decantation etc.

Teaching Unit / Test Rig for performance of Falling film and Packed towers with different packings for absorption process.

Teaching Unit Test Rig

Teaching Unit for studying Distillation / Distillation Test Rig.

Teaching Unit for studying Distillation

The unit is meant for Methanol-Water distillation. The plant is fitted with an electrically heated reboiler. Vapour generated in the reboiler rises through the column (Bubble cap type / Sieve tray type / Packed column type) and is condensed in a vertical water-cooled condenser.

Plant operation is controlled from a free-standing control panel consisting of flow controllers, temperature and pressure indicators and services controllers. All major process items and pipework are manufactured from BVR borosilicate glass with other contact parts in , PTFE and stainless steel.

Heat Exchanger Test Rig.

Heat Exchanger Test Rig

The unit is fitted with three heat exchangers namely Shell & Tube type, Shell & Coil Type & Plate Type, each of which can be studied separately. Each heat exchanger can be operated as either a steam condenser or liquid/liquid heat exchanger in counter or co-current flow. Temperature and pressure indicators are positioned in strategic locations to allow the heat exchangers to be monitored and basic heat transfer mechanisms to be studied. The operations can be controlled from a control panel fitted with various controllers. A diagram of the unit is also supplied and this ensures simple identification of valves and recording of plant variables.

The Mixer-settler system is fabricated and assembled in a compact modular design. The mixer as well as the settler are both integrated together instead of being separate entities. This allows the system to be compact and ideal for laboratory and R&D usage. A single stage of Mixer-Settler consists of a mixing zone and settler decanting zone connected to each other through a Weir zone. A brief description of the zones is as follows:

Mixing System

The Laboratory mixer consists of a special glass / ss (as per choice) mixing zone, suitable high speed agitator and a variable speed drive. Besides providing an intimate dispersion the stirrer provides the necessary pumping action. This eliminates the need for external pumps and ensures a large interfacial area for mass transfer.

The energy required to produce this dispersion will depend very much on the characteristics of the material and the system used (interfacial tension, viscosity, flow rates, etc). Between the mixing and separation zones, a weir is incorporated to prevent back mixing taking place and maintains the level of liquid in the mixing zone. Besides it also acts as a baffle to dampen the flow of liquid into the decanter (settler)for enhancing efficient phase separation.

Settling System

The settler comprises a horizontal cylindrical pipe which depending upon size may be one or more pipe sections. From the settler, the outlet of the heavy phase, is controlled by an overflow valve. The design of the settler will be influenced by the throughput of both phases and the material physical properties (density difference, viscosity, interfacial tension etc).

Different stages can be connected to each other and the interconnecting pipelines can be done as per your required flow logic. The whole assembly would be controlled through a control panel consisting of suitable circuit breaker MCBs, Relays, digital controllers etc.

Wiped Film Evaporator is a Thin Film Evaporator and consists of a jacketed glass / SS / other corrosion resistant pipe section in which is rotating a corrosion resistant PTFE / SS / other corrosion resistant wiper system with suitable rows of blades supported by suitable bearings.

Wiped Film Evaporators

These give a high wiping frequency and therefore, an optimum renewal speed of the boundary layer, which are pre-requisites for thorough mixing of the liquid film and for high evaporation rates. The wipers are forced against the evaporator wall by centrifugal force, and this can be varied via the speed of rotation of the drive, depending on the viscosity of the liquid.

Inherent features of our Wiping Film Evaporators:

  • Made of corrosion resistant materials.
  • Lowest possible working temperatures possible.
  • Very low residence time.
  • Visual observation while using Borosilicate glass.
