Definitions
- This disclosure relates generally to a process and system for plant essence extraction from a source of plant material.
- the disclosure relates to a process and system for producing plant essence that are energy efficient and provide a significantly reduced carbon foot print.
- plant essence that are energy efficient and provide a significantly reduced carbon foot print.
- a plant essence is a concentrated hydrophobic liquid containing volatile aromatic and other compounds from a plant.
- Plant essences are also known as volatile oils, ethereal oils, aetherolea, or the oil of the plant from which they were extracted, such as for example lavender oil, eucalyptus oil or tea tree oil.
- a plant essence typically contains the characteristic fragrance of the plant from which it is derived.
- Hydrodistillation is a technique for extraction of essential oils. It is used for its simplicity but requires high energy consumption for heating and cooling. Many organic compounds present in plant essences tend to decompose at high sustained temperatures. Separation by hydrodistillation is where water or steam is introduced into the distillation apparatus. The water vapour carries small amounts of the vaporized compounds to a condenser, where the condensed liquid phase separates, allowing for easy collection. Usually the immediate product is a two-phase system of aqueous and organic distillates, allowing for separation of the components by decantation, partitioning or other suitable methods.
- Mechanical Pressure Expression is a technique whereby physical force is exerted by mechanical presses to express a liquid component from plant biomass.
- An example of this is the pressing of olives to derive olive oil.
- This system can be batch specific or an in-line continuous pressing system.
- Gas Pressure Expression is a relatively new process, primarily using carbon dioxide (C0 2 ) in an enclosed vessel to generate high physical pressure to push the essence from the biomass. This technique has the advantage of achieving extraction under any temperature condition, preserving any volatile elements which can be lost in a heat -based hydrodistillation process.
- Steeping Extraction is a process of extracting plant biomass elements using water in its liquid phase as a solvent. This may be done at various temperatures.

In a further form, step b) is undertaken within 48 hours, and preferably within 24 hours after step a). In a further form the hydrogen storage apparatus is proximate to where processing steps a) and b) are undertaken.
