• 35’ Vacuum Flash Vaporization / Vacuum Distillation Effect Accepted by Western Mainstream( WM)
• ■ 35’ Low Pressure / Vacuum Flash Vaporization / Vacuum Distillation / Flash evaporation: Can be linked to 34’ Ice / Vacuum Freezing. Also widely used but rare stand alone or major use in:
• M2( desalination): Easily built in as part of very low heat recovery in existing factory / generator station etc. Often private use or test operations: as low as 26-32 ° C:( Kerala / Karunya State Council for Science, National Institute of Ocean Technology of Chennai, Passarell Desalination +). At 45 ° C:( Inst. of Ocean Energy Saga +), Not on tech list but low cost high temperature vacuum freezing is widely used- but not
for freeze desalination. 、 P2( Wastewater cleaning): sometimes lowest cost solution: Vapor Compression Evaporation- Distillation / Mechanical Vapor Recompression( MVR): low grade heat water goes through venturi / orifice to made into steam partially at low temp, then that steam gets compressed to generate heat( ie far more than COP > 1: overunity) and this heat is used to raise liquid temperature itself to enable efficient low cost recovery of water, also often uses vortex flow / hydrocyclone for efficient solids separation( ENCON Evaporators, PureStream, Salttech DyVaR ZLD +),
• W2( Oil separation): various module based system removes oil emulsion( VACUDEST ClearCat- H2O GmbH +), Reduces / solves shortcomings of cleaning off solvent after industrial washing( VAC Aero +).( Centrifugal) Molecular Distillation / Short Path Distillation( high vacuum distillation): upto 1x10 {-6 } to {-9 } bar( 1bar is sea level atmospheric pressure)- this effect can prevent molecule from colliding with each other with same kind or other types during distilling process / separation and storage. Hence Molecular Distillation( MD) can be useful but sometimes underutilized for specialty reaction / temperature sensitive water dissolved matter, compounds, or oil separation / purification, isotope separation, while MD is std processes in lab analysis or pharmaceutical manufacturing( TMC Industries, ULVAC)+)
