Solvent and Desorbate Treatment Systems
AMCEC solvent and desorbate treatment systems are custom designed to meet each client's requirements. AMCEC uses the adsorption power of activated carbon (about 1,200 m2 of surface area per gram) to recover organic solvents. With recovery efficiencies as high as 99%, the economic potential is significant. Many users further reduce their operating costs with our ECOVAP energy saving units and enhance their return on investment with our solvent treatment systems.
Recovery begins when the Solvent Laden Air (SLA) passes through deep static beds of activated carbon. The solvents are retained in the activated carbon pores and the cleansed air is discharged to the atmosphere.
Through staggered adsorption and desorption cycles monitored by analyzers and computer, each bed is periodically regenerated by counter flow of steam or inert gas that heats the carbon.
During the regeneration phase, the solvent vapors are released from the carbon and carried by steam or inert gas to condensation, decanting and solvent treatment units.
A wide range of cost effective processes and equipment are offered:
- air stripping
- steam stripping
- steam distillation
- chemical drying
- separation by selective adsorption
- separation by membrane
One of the most commonly used treatment processes is steam distillation. The desorbate recovered from the steam regenerated carbon adsorption system is processed in high efficiency packed or trayed columns to separate water and solvents.
Alternatively, AMCEC offers inert gas regenerated solvent recovery systems that recover solvents with less than 0.1% water.
