Solvent recovery systems recover and re-use solvents from manufacturing processes. Solvent laden air from the processes is passed through an activated carbon bed. When the carbon bed is nearly saturated with solvent, a steam-down cycle occurs to condense out the solvent for re-use. The carbon is then regenerated for another collection phase. Two carbon beds are used so that one bed can process the solvent-laden air while the other one is regenerating.
Flame Ionization Detectors (FIDs) are used to monitor the carbon bed exhausts for solvent breakthrough and to control the switching of the carbon beds when they have become saturated. They also improve the effectiveness of the carbon bed system in terms of the quantity of solvent recovered, reduced emissions, improved bed cycling and lower steam regeneration costs.
- Our SNR650 Flame Ionization Detector monitors the hydrocarbon levels of the carbon beds in real time and reacts quickly to switch beds, allowing for optimum performance.
