Your test rig bench is conceptually fine, but it could be improved by a heating technology which is not on the market yet, but that you could use at lab level, depending on the purpose of use.
It is based on the application of an electromagnetic field of a very high intensity.
The dielectric properties of the oil are such that the cells containg such oil - cells which also contain water - will be transformed (becoming porous or bursting) by the pressure difference created by the water temperature increase, thus allowing the extraction yield to be significantly increased.
Further details can be discussed : you may contact me at [email protected].
Scientific bibliography is available.
Looking forward to it,
Best regards,
