320L Explosion Proof Solvent Recovery Machine For Highly Viscous Liquids
What is a solvent recovery or solvent reclamation system?
Pilot Plant Fabrication A solvent recovery system is a process system that takes effluent and extracts useful raw materials back out of the process waste stream. They can reduce the demand for raw materials, by recovering chemicals that can be reused in production, or used to flush the system between runs. They can also help manufacturers meet regulatory requirements or process standards by cleaning waste streams before they are released from the plant.
The recovery of solvents from effluent can be achieved with a variety of technologies. A common one is solvent distillation systems, but liquid-liquid extraction, absorption systems, film evaporation, crystallization, and membrane separation can also be used, depending on the application.
——Design
Horizontal or vertical shell-and-tube heat exchanger or plate heat exchanger, with flash vessel/separator and circulation pump.
——Operation
The liquid is circulated through the heat exchanger by means of a circulation pump, where it is superheated at an elevated pressure, higher than its normal boiling pressure. When entering the separator, the pressure in the liquid is rapidly reduced resulting in some of the liquid being flashed, or rapidly boiled off.
Since liquid circulation is maintained, the flow velocity in the tubes and the liquid temperature can be controlled to suit the product requirements of the pre-selected temperature difference.
——Particular features
Less foul – boiling/evaporation will not take place on the heating surfaces, but in the separator. Fouling due to incrustation and precipitation in the calandria is therefore minimized.
Optimized heat exchange surface – flow velocity in the tubes determined by the circulation pump.
——Fields of application
Liquids with a high tendency for fouling, highly viscous liquids, as the high concentration step in multiple-effect evaporation plants.
Forced circulation evaporators are suited as crystallizing evaporators for saline solutions.
