Abstract: A scalable technology for purifying ethanol, wherein the vaporization of ethanol is coupled with a chromatographic rectification process comprising feeding a vaporized ethanol/water mix onto a plurality of molecular sieve beds to produce dehydrated ethanol vapor, which can then be condensed to recover purified dehydrated ethanol liquid. The scalable technology process is suitable for farm-scale production of fuel-grade ethanol, having the added benefit of allowing wet distillers grains to be used on-site as live-stock feed. By reducing energy requirements, costs and pollution, the output can be scaled to produce fuel-grade ethanol at quantities of anywhere from about 1000 gallons per year to upwards of hundreds of millions of gallons per year. Particularly beneficial versions utilize a plurality of smaller molecular sieve beds in series and use heat generated during desorption and regeneration of the molecular sieve beds as an energy source to aid in the vaporization step.

Abstract: An evaporation system uses the weight of condensed liquid as an energy source. An inlet feed is introduced into an enclosure through an inlet. The inlet feed is vaporized in an evaporation region of the enclosure, and condensed to a liquid in a condensation region of the enclosure. The condensed liquid collects in a liquid region of the enclosure. The liquid region has an outlet. A blower between the evaporation region and the condensation region maintains the condensation region at a higher pressure than the evaporation region. The level of the liquid in the liquid region defines the volume and pressure of the evaporation and condensation regions, such that as the liquid is drained from the outlet, at least in part by the weight of the liquid, the pressure in the evaporation region decreases. The flow through the inlet and the outlet is regulated to maintain the pressure in the evaporation region at a pressure that tends to vaporize the inlet feed.

Abstract: A heat transfer fluid medium (25) within the closed system is arranged to boil to form a vapor in the evaporation section (12) and such that release of heat from the condensation section (11) to the fluid to be heated (4A) causes the vapor to condense to liquid in the condensation section (11). The conduit forms a loop (10) and back flow in the loop (10) is prevented by providing a trap (27) of liquid in the conduit at a position adjacent to or at the evaporation section (12). The flow around the loop (10) at high speed sufficient to carry all condensate forwardly is caused solely by application of energy to the system by the heat source (21) without mechanical pumping. Inert gases are collected immediately upstream of the trap (27) and can be purged therefrom.

Abstract: One or more water distillation chambers are provided wherein water containing salt or other impurities enters an upper inlet at a chamber and flows down a solar heated evaporative surface. The evaporative surface may be the interior of a pipe or the surface of a bottom sheet enclosed by a cover. In this way, the steam produced in the process will be constrained and be guided into a steam drum. The steam drum interior has cooling tubes whereby vapor entering the steam drum will be condensed into fresh water and collected for use. The cover may be heated to limit the amount of vapor condensing back into water before entering the steam drum. Multiple evaporation chambers and steam collection stages limit the distance water vapor must travel before entering a steam drum of a given stage, thereby minimizing the loss of water vapor through re-condensation before the vapor enters the steam drum.
