How does , those who do. vapor assisting to push any liquid solvent in columns (to further expel your extract from column packed material), result for any of those who use this method of a vapor assist.
For example: utilizing the boiled off solvent (warm/hot vapor) from your extract to recirculate back to the top of the material column to further feed just warm/hot vapor to expel left over extract solution in material column.
In this example the closed loop is active, with a MVP.
+there are 3 columns each holding 3lbs of material. (4"x48") we pack socks.
+each column is connected to the same collection vessel (16"x48")
- from the recovery vessel. we redirect the warm/hot vapor right after the recovery pumps outlet & before the condensing coil ( jacketed solvent recovery tank has internal condensing coil), back to the top of the material columns and push further an remaining liquid.
also keep in mind a manifold was put together with valve control for the redirected warm/hot vapor pressure pathway. Recovery ports are closed at this time to allow the redirected pathway to be the only way for the pressure to move.
+the recovery pump is on at the same time to move the pressure…
if any questions to explain further please lmk…
