  • Molecular sieve depressurization recovery system
    Patent number: 9415342
    Abstract: A system for depressurizing a molecular sieve used in ethanol production is provided. The ethanol production system includes a plurality of on-line molecular sieve bottles for removing water from ethanol production. When the molecular sieve bottle becomes saturated with water it is taken off-line to depressurize it. The depressurization and removal of water is done from the product discharge end resulting in an approximately 5% to 10% reduction in external energy required to run the ethanol production line.

  • MULTI-STAGE SCRUBBING SYSTEM AND METHOD FOR ETHANOL VENT STREAMS
    Publication number: 20110277633
    Abstract: A multi-stage scrubbing system comprises a pre-scrubber system structured to receive a vent stream therein and pre-scrub the vent stream with a pre-scrubber fluid. The pre-scrubber system includes a first outlet for discharging a pre-scrubbed vent stream and a second outlet for discharging a discharge stream of pre-scrubber fluid. A main scrubber system is fluidly coupled to the first outlet of the pre-scrubber system for receiving and further scrubbing the pre-scrubbed vent stream.
