I suggest you Maha Hasni extract essential oil through the Clevenger apparatus, because there only you can easily separate your expected essential oil from water.

Now back to your problem, you can simply put your oil vessel in air titted beaker having much of mesh sized silica pellet.

Dear Maha Hasni . The best method is Steam Distillation. See the link: https://www.google.com/amp/s/www.newdirectionsaromatics.com/blog/articles/how-essential-oils-are-made.amp

The separation of solvent from volatile oil/essential oil is not commonplace, initially. It is better to extract volatile oil/essential oil from conventional techniques and the solvent is determined through detection techniques in the analytical chemistry. Finally, the relevant adsorption peak is separated and identified from the other analytes.
