First of all, I would like to thank you for your continued interest in my question; secondly, I need to apologize for a mistake that I have made: methanol can be used as an effective solvent for psilocybin and baeocystin, and is sometimes referred to as "wood naptha." I misunderstood the colloquialism and interpreted methanol as being synonymous with VM&P Naptha.
As per your confusion regarding my usage of the terms "primary," and "carrier" solvent, I apologize for my lack of clarity. The Tamisium Essential Oils Extractor consists of a column that contains the organic material that seals to a recovery tank. In normal extraction (THC for example), the recovery tank is filled with acetone, the column is filled with cannabis, and butane is introduced into the device via one-way valve at the top of the column. The desired essential oils are deposited into the acetone bath, and through temperature inversion the butane is reclaimed into a separate/additional reclamation tank (for re-use). In this example, butane is the only, and therefore, primary solvent.
The Tamisium can also be used to extract from polar biomass, but in order to do so, a polar solvent must be used. To accomplish this, the separate/additional reclamation tank is addressed first. The polar solvent (in my hypothetical case: methanol in a liquid state), is deposited in the reservoir which is then sealed and pressurized with aerosol butane. The biomass is deposited in the column and then the solvents are introduced through the top valve mentioned above.
The Tamisium is a closed system that required pressurization to work, so in this case butane becomes the "carrier" solvent which gives the polar methanol "primary" solvent a ride through the column to work its' magic.
