Hi Veanuga,

You are cracking oils like they do to make gasoline, etc. Any textbook on this phenomenon would provide all the details and instrumentations necessary.

The following provides an overview of the cracking process. While boiling the medium which creates possibly several forms of chemical vapors including your desired vapor, it must then be extracted at some strategic vapor height above the boiling fluidm, where it gets sucked through an exit port to be chilled and condensed into your desirable product. As you noted, temperature controls are important to know when the phase change to a vapor happens and for what chemistry. Also, as the oil starts to boil it may have different chemical compounds that vaporize at different temperatures (the cracking process) so you must facilitate a technique that extracts your exact oil-vapor from a staged system that creates vapor products at different temperatures and height levels above the basic oil being heated to boiling.

Finding the correct cracking point process height for your desired vapor, you must provide an extraction system that sucks only your vapor out through an exit port while other vapors flow past. The vacuum mechanism itself would be sufficiently downstream such that you are essentially sucking only air that gets dumped (which may be perhaps purposely fed into your exhaust network) and not precious vapor at that point. Meanwhile, the vapor is being condensed into your oil product as it moves along your mechanism, preferably using a gravity feed system, and drips into a storage container.

These various mechanisms may possibly be needed in your cracking process and should help you determine what instrumentation is actually required. If your expected extraction efficiency is not extravagant, you may be able to avoid many of these mechanisms but only if minor samples of the desired oil are needed. However, you must use trial and error to determine what to mechanism to avoid and what is necessary.

Thanks for view and opinion , it really help in my research and in my project.
