  • Patent number: 12151193
    Abstract: An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

  • Patent number: 9249064
    Abstract: A method and system for converting intermittent renewable energy and renewable carbonaceous feedstock to non-intermittent renewable electrical and thermal energy, storing it as fuels and chemicals and using it to capture and re-use or dispose of CO2 emissions. The system in a preferred embodiment is realized through the generation of non-intermittent renewable electricity utilizing intermittent renewable energy sources along with gaseous fuel from renewable carbonaceous feedstock, producing oxygen and hydrogen from non-intermittent renewable electricity and utilizing the oxygen and hydrogen as required for gasification of renewable carbonaceous feedstock to produce gaseous fuel stream and gaseous intermediate stream, utilizing the gaseous intermediate stream to produce renewable fuels and renewable chemicals, and utilizing oxygen for oxy-rich combustion for concentrating CO2 emissions for easy processing, re-use and disposal.

  • Patent number: 8506910
    Abstract: A process and system for producing high octane fuel from carbon dioxide and water is disclosed. The feedstock for the production line is industrial carbon dioxide and water, which may be of lower quality. The end product can be high octane gasoline, high cetane diesel or other liquid hydrocarbon mixtures suitable for driving conventional combustion engines or hydrocarbons suitable for further industrial processing or commercial use. Products, such as dimethyl ether or methanol may also be withdrawn from the production line. The process is nearly emission free and reprocesses all hydrocarbons not suitable for liquid fuel to form high octane products. The heat generated by exothermic reactions in the process is fully utilized as is the heat produced in the reprocessing of hydrocarbons not suitable for liquid fuel.
