  • Dehydration of ethanol
    Patent number: 4351732
    Abstract: Process and apparatus for dehydrating liquid phase ethanol in an adsorber unit containing at least two towers that cycle between adsorption and desorption cycles, characterized in the desorption cycle by an indirect heating volatilization of absorbed and adsorbed liquid at ambient pressures, and by a final stages desorption under sub-atmospheric pressures. In preferred practice, an inert sweep gas at sub-atmospheric pressures assists in removal of vapors evolved in the final stages of the desorption cycle.

  • Process for treating metals using recycled gases
    Patent number: 4219324
    Abstract: A process is described for treating metals in a furnace by indirect heating techniques, e.g., by using a radiant tube heater, wherein the gas used for heating is passed out of the furnace, treated in a known manner, and passed back into the furnace to serve as the source for the treating atmosphere or as a carrier gas. Carburization of metals can be carried out by this method which results in a savings in fuel and overall operational expense.
