Methods, systems, and devices for liquid hydrocarbon fuel production, hydrocarbon chemical production, and aerosol capture are provided. For example, a carbon-oxygen-hydrogen (C—O—H) compound may be heated to a temperature of at least 800 degrees Celsius such that the C—O—H compound reacts through a non-oxidation reaction to generate at least a hydrocarbon compound that may be at least a component of a liquid hydrocarbon fuel or a hydrocarbon chemical. The liquid hydrocarbon fuel may be a liquid when at a temperature of 20 degrees Celsius. The C—O—H compound may include biomass. In some cases, the hydrocarbon compound produced through the non-oxidation reaction includes a hydrocarbon aerosol form as the hydrocarbon compound at least as it is produced or cools. Some embodiments include aerosol capture methods, systems, and devices, which may include passing a hydrocarbon aerosol form through a material in a liquid phase in order to gather the aerosol material.

A gas processing system is described herein. The gas processing system includes a number of co-current contacting systems configured to contact a sour feed gas stream including an acid gas with a solvent stream to produce a partially-sweetened gas stream and a rich solvent stream including an absorbed acid gas. At least one of the co-current contacting systems is configured to send the rich solvent stream to a regenerator. The regenerator is configured to remove the absorbed acid gas from the rich solvent stream to produce a lean solvent stream. The gas processing system also includes a solvent treater configured to treat at least a portion of the lean solvent stream to produce an enhanced solvent stream, and a final co-current contacting system configured to contact the partially-sweetened gas stream with the enhanced solvent stream to produce a partially-loaded solvent stream and a final gas stream.

A process for producing a purified gas stream from a feed gas stream comprising methane, carbon dioxide, and aromatic compounds selected from the group of benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene involves measuring respective amounts of carbon dioxide and aromatic compounds in the feed gas and providing the measured amounts to a controller. The feed gas stream and a stream of absorbing liquid comprising at least sulfolane, water and a secondary or tertiary amine is provided to an acid gas removal unit (AGRU) The controller adjusts one or more of composition, temperature, and flow rate of the stream of absorbing liquid to the AGRU to prevent amounts of aromatic compounds in an AGRU outlet stream from exceeding a predetermined maximum threshold.
