Pollution Control: Solvent Recovery

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.

Happy Thanksgiving

We ought to make the moments notes

Of happy, glad Thanksgiving;

The hours and days a silent phrase

Of music we are living.

And so the theme should swell and grow

As weeks and months pass o’er us,

And rise sublime at this good time,

A grand Thanksgiving chorus.
