5.15.3 Isolating the Solvent Removal Column and Removing Solvent Vapors
1
Open isolation valve A. This allows the system to continue to circulate through the
purification column.
2
Close isolation valves B and C. This isolates the solvent removal column so that you can
evacuate it without affecting the rest of the system. It is important to open valve A prior to
closing B and C so that flow to the blower is not interrupted.
3
Turn evac/refill valve to evacuate.
4
Allow vacuum to pull on the column for at least 24 hours.
5
To begin circulation through the solvent removal column again, see
