Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method for upgrading biogas wherein biogas is provided in one or more pressurized vessels. A plurality of pressurized feeds are produced in a process comprising decompressing biogas from at least one of the one or more vessels and as the biogas is decompressed providing portions of the biogas at successively lower pressures. The plurality of pressurized feeds, which have different average pressures, are provided to a pressure swing adsorption process wherein an adsorbent bed is pressurized by successively feeding gas from each of the pressurized feeds in the plurality into the adsorbent bed in order of increasing average pressure. Accordingly, compression costs can be reduced.

Abstract: 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.
