Heat assisted solvent to gas dispersion (STG) open source patent

This invention is for the basic technology of Heat Assisted Solvent to Gas Dispersion.  Also known as STG technology - Solvent to Gas.



The basics of the invention is the solvent (which can be solid, liquid, gas or any other state of matter) that may or may not contain molecules/atoms/compounds etc. of interest is volatilized into a gaseous suspension or solution (preferably with droplet size smaller than 5 um exiting the device) using both heat transfer and dispersion methods.  Dispersion is defined as forcibly introducing gaseous material in any way, which may or may not include cavitations, into the solvent of interest.  This does not include cavitations naturally occurring from the boiling process, but these cavitations can be a part of what this technology does.  But the scope of this invention is to only cover inventions that forcibly disperse a gas into/through/over/around the solvent and this may or may not include natural force-less boiling gas dispersion. This technology can be used for any purpose including but not limited to: Research, propellant, fuel, medical purposes, non-medical personal use, disposal, energy, delivery or transport, or any other industry or field for any purpose.  This can be used on the massive industrial or governmental scale or for personal portable devices, home or car devices, micro scale, nano scale, pico and femto scale, and anything in between or combination.  Anything that can benefit from efficiently vaporizing a solvent.  Solvent can be anything with solvent properties including water, aqueous solutions, polar solvents, non-polar solvents, dry ice, liquid nitrogen, combination, or anything else that can be used as a solvent in any capacity.  The process of dispersing the solvent into the gaseous phase can be utilized for co-dispersing of other items of interest.  This can be anything, but for example it could work similarly to steam distillation of essential oils from plant matter.  In that process steam is used to extract essential oils from plant matter which are re-condensed into liquid oils.  This process can include any thing like that where the solvent being dispersed (which can be partial and slow or complete and fast or any combination) is utilized to accomplish other purpose(s).  This current invention is not for collecting or harvesting this material such as steam distillation and collection of essential oils, but solely for dispersing this material into the gaseous phase.  Material can be collected after an STG process, but this recovery is not part of this technology.

I want to make it abundantly clear that this is not intended for and will not work with "vape juice" or "e-liquid" or any other "e-cigarette" nicotine substance.  Liquids containing a high percentage of glycerine simply will not be dispersed by any reasonable STG process.

"Vape Mod" or "Vape device" which is the electrical device that can power a resistance coil; may be used to create heat for this invention via the 510 adapter.  This shows that these electrical devices have more uses than just for e-cigarettes and therefore are not under the purview of the FDA.

The temperature used for heat transfer can be ambient temperature or elevated temperature above ambient which is preferred.  Heat just has to transfer to the solvent in any way to increase it's vapor pressure and make it tend towards evaporation.  Next, gaseous matter needs to be introduced and/or mixed into the solvent to further disperse the solvent into the gaseous phase.  The way this works is forcing gas or cavitations into/through/around/over the solvent and possibly breaking up through the surface of the solvent which would counter the surface tension of the liquid (which tries to keep the solvent together) by adding shear forces (if the solvent is liquid) to help break off clumps of liquid into the gaseous phase.  Preferably next (but not required) would be heat transfer elements (optionally extra shear/dispersion methods as well) that increase the heating surface area to help finish evaporating/dispersing the liquid blobs into the gaseous phase and/or keeping the vapor from condensing on the apparatus.  Next preferably would be introducing ambient air or another gas to lower the vapor saturation of the gas (diluting it) and possibly cooling it as well.  This can even be done using a vortex of gas introduction if desired.  If utilizing the solvent to propel other desired molecules into the gas phase, then the solvent can be recaptured if desired and reused.  In the end there will be a gas that includes material of interest suspended or in solution with the gas.

Gas for dispersion and/or extra gas insertion can be introduced in any way but can be from pumps, gas injection, breathing/inhaling, gas buoyancy, or anything else.  If a dispersion element(s) are used to disperse the gas in the solvent, anything can be used.  Capilary tubes can be used if desired and if the ID of the tubes are correct for the height of the liqhid above them, they may not leak.  For example if 1.1mm ID or smaller capilary tubes are used and the liquid level above them isess than around 29/64", then water in this cashe shouldn't leak out the capilary tube(s).  Or a typical fritted gas dispersion tube can be used as an example and to prevsnt this from leaking the inlet could just be above the liquid level.  This air inlet can also be used to load solvent if desired, moniter the liquid level automatically or visually, used to automatically add solvent or other material, etc.

The solvent, and/or material of interest, can be introduced into the chamber/device by siphoning, pumping, squirting, injection, aliquoting, etc.  All or some of the solvent can be dispersed at a time.

Going back to the "steam distillation" essential oil example; if for example distilled water was heated and gas was dispersed through it, and either essential oil was in/on the water or in herbal material above the water and the essential oil was desired to be volatilized, then the steam/water particles could help quickly shuttle the essential oil into the vapor phase, and if desired, the water could be condensed and returned to the device while much of the essential oil remained in the vapor phase.  This example may or may not be practical but is just an example of the sort of thing this technology can accomplish.
