Patent number: 11946006Abstract: A method for producing a fuel includes transporting one or more pressure vessels containing pressurized biogas from a first location to a second location, and removing biogas from the one or more pressure vessels at the second location. The fuel production process is improved by controlling the decanting flow rate to provide a total decant time greater than 30-40 minutes, by actively heating biogas contained within the one or more pressure vessels, or some combination thereof.Type: GrantFiled: July 6, 2020Date of Patent: April 2, 2024Assignee: logen CorporationInventors: Brian Foody, Patrick J. Foody, John Dechman

Patent number: 11746301Abstract: A method for providing a fuel includes providing a partially purified biogas at a first processing site, where the partially purified biogas is produced by multiple biogas sources and/or from multiple feedstock sources. The partially purified biogas is compressed, fed to a mobile tank, and transported by vehicle to a second processing site. At the second processing site, which may also receive biogas from a plurality of biogas sources, the partially purified biogas is further processed to produce a fuel or fuel intermediate.Type: GrantFiled: February 28, 2022Date of Patent: September 5, 2023Assignee: Iogen CorporationInventors: Patrick J. Foody, John Dechman

Publication number: 20230053930Abstract: A process and/or system for producing one or more biofuels, wherein biogas (e.g., partially purified biogas produced by removing water, hydrogen sulfide and/or carbon dioxide from raw biogas) is transported by vehicle in one or mobile vessels. De-pressurization of the mobile vessels provides a change in pressure that can be used to provide work, cooling, and/or increased pressure for the production process. Combustion of the biogas produces heat and/or power used to reduce a carbon intensity of the biofuel or biofuel intermediate.Type: ApplicationFiled: December 21, 2020Publication date: February 23, 2023Inventors: Patrick J.

Publication number: 20210317377Abstract: A method for providing a fuel includes removing hydrogen sulfide and/or carbon dioxide from biogas to provide partially purified biogas, which is filled in a mobile storage system. The partially purified biogas is transported to a centralized processing facility, in the mobile storage system, by truck, rail, or ship. At the centralized processing the partially purified biogas is further processed, either to produce a fuel that is renewable or has renewable content, or to produce renewable natural gas, which is used to produce the fuel that is renewable or has renewable content.Type: ApplicationFiled: July 9, 2019Publication date: October 14, 2021Inventors: Patrick J. Foody, Brian Foody, John Dechman

Publication number: 20210275961Abstract: A method for providing renewable natural gas (RNG) includes removing hydrogen sulfide and/or carbon dioxide from biogas to provide partially purified biogas, which may be stored in a mobile storage tank. The partially purified biogas is transported to a biogas upgrading facility, at least partially by truck, rail, or ship. At the biogas upgrading facility, the partially purified biogas is further purified to provide the RNG, which can be injected into a distribution system (e.g., natural gas grid) and/or provided for use in transportation.Type: ApplicationFiled: July 9, 2019Publication date: September 9, 2021Inventors: Patrick J. Foody, John Dechman

Publication number: 20210155864Abstract: A method for providing a fuel includes providing biogas from a plurality of biogas sources, the biogas from each biogas source produced in a process comprising filling a vessel with raw biogas or partially purified biogas to a pressure of at least 1500 psig and transporting the filled vessel to a centralized processing facility by vehicle. A fuel is produced in a fuel production process that includes feeding the biogas transported to the centralized processing facility to a biogas upgrading system that is configured to provide a carbon dioxide removed from the biogas. The removed carbon dioxide is provided for transport by vehicle and/or pipeline and/or sequestered to offset greenhouse gas emissions attributed to compressing the biogas for transport.Type: ApplicationFiled: January 6, 2021Publication date: May 27, 2021Inventors: Patrick J. Foody, Brian Foody, John Dechman

Patent number: 10995314Abstract: A process for producing ethanol from lignocellulosic biomass includes adding at least one of sulfur dioxide and sulfurous acid to the lignocellulosic biomass to provide an equivalent sulfur dioxide loading of at least 10 wt % sulfur dioxide to dry lignocellulosic biomass. The acidified lignocellulosic biomass is pretreated at a temperature above about 185° C. and for a pretreatment time less than about 10 minutes, to provide a pretreated biomass composition wherein the biomass is readily hydrolyzed by enzymes. Advantageously, sulfur dioxide from at least one of the flash stream and a stream derived from the flash is recovered and recycled back into the process.Type: GrantFiled: March 16, 2016Date of Patent: May 4, 2021Assignee: Iogen CorporationInventors: Brian Foody, Daniel G. MacDonald, Kristin Martens, Natacha Leduc, John Dechman, Robert Griffin

Patent number: 10655149Abstract: A process for hydrolyzing lignocellulosic biomass includes feeding lignocellulosic biomass into a pretreatment reactor, wherein the pretreatment reactor has a headspace charged with sulfur dioxide previously used in the pretreatment of lignocellulosic biomass. In addition, acid comprising sulfur dioxide and/or sulfurous acid is fed into the pretreatment reactor (e.g., with the lignocellulosic biomass, separate from the lignocellulosic biomass, or a combination thereof) and the lignocellulosic biomass is heated. As the pretreated lignocellulosic biomass is discharged from the pretreatment reactor, at least a portion of the sulfur dioxide used in the pretreatment is retained in the headspace.Type: GrantFiled: September 16, 2016Date of Patent: May 19, 2020Assignee: Iogen CorporationInventors: John Dechman, Brian Foody

Patent number: 10421667Abstract: A process for producing one or more products from a lignocellulosic feedstock comprising treating the lignocellulosic feedstock to produce sugar in one or more stages comprising addition of acid, base or a combination thereof and introduction of heat. The addition of the acid, base, or a combination thereof produces a salt. The sugar is fermented to produce a fermentation product and the fermentation product is recovered. A stream comprising the salt is treated by wet oxidation with the introduction of heat. A stream comprising salt resulting from the wet oxidation is provided for use as a salt product or a process chemical for introduction within the process. Heat from the wet oxidation may be supplied to any stage of the process in which heat is introduced.Type: GrantFiled: March 16, 2016Date of Patent: September 24, 2019Assignee: Iogen CorporationInventors: Patrick J.
