  • Method and system for production of oxalic acid and oxalic acid reduction products
    Patent number: 9267212
    Abstract: The present disclosure is a method and system for production of oxalic acid and oxalic acid reduction products. The production of oxalic acid and oxalic acid reduction products may include the electrochemical conversion of CO2 to oxalate and oxalic acid. The method and system for production of oxalic acid and oxalic acid reduction products may further include the acidification of oxalate to oxalic acid, the purification of oxalic acid and the hydrogenation of oxalic acid to produce oxalic acid reduction products.
    Type: Grant
    Filed: March 20, 2014
    Date of Patent: February 23, 2016
    Assignee: Liquid Light, Inc.
    Inventors: Zbigniew Twardowski, Emily Barton Cole, Jerry J. Kaczur, Kyle Teamey, Kate A. Keets, Rishi Parajuli, Alexander Bauer, Narayanappa Sivasankar, George Leonard, Theodore J. Kramer, Paul Majsztrik, Yizu Zhu

  • FRACTIONAL CONDENSATION PROCESSES, APPARATUSES AND SYSTEMS
    Publication number: 20120298498
    Abstract: The present invention provides fractional condensation apparatuses, systems and methods that can recover volatile products from highly diluted liquid and vapor feed mixtures with high purity and recovery yield, both in batch and continuous distillation, while being also designed to achieve low-cost and efficient recovery processes. Single apparatuses and columns can be connected to each other to expand or shrink the column length for desired separation. The apparatuses, systems and methods can be applied to separate mixtures with both narrow and wide boiling point ranges.
