So how do I go about clearing my recovery lines After I finish my final recovery, I run 2 appions. I seem to have such a major issue with this. Once my system has reached my desired vacuum depth (20hg) I close my recovery valve and isolate the pump from the system and allow it to rutk, and attempt to push the remaining solvent into the tank. This does not seem to work that well as once I close the tank valve and then shut the pumps off there is still vapor in the lines. It almost does not matter how long I allow the pumps run. I know this is because under vacuum conditions, the pumps have no molecules to compress and create compression towards the tank. The only way I can clear the lines is to open the recovery valve and allow atmosphere to enter the pump and push the solvent through. In the event of allowing atmosphere into the pump I do shut the tank valve while there is still a small amount of butane in the line to reduce the possibility of atmosphere entering the tank.
HELP ME FIGURE THS OUT PLEASE THANK YOU SO MUCH
