Processes and methods of recovering desired products from fermentation stillage are presented, including processes and methods of recovering lipids and aqueous materials.

Recovery of desired co-products from fermentation stillage streams

A system for producing an auxiliary fuel stream containing a low concentration of sulfur compounds from a primary fuel stream includes a first separation stage to separate a portion of a primary fuel stream into a first vapor permeate stream and a first retentate stream, a first separation stage partial condenser connected to the first vapor permeate stream condensing a portion of the first vapor permeate stream into a first liquid stage stream and a first vapor stage stream, and a second separation stage partial condenser condensing a portion of the first vapor stage stream into a second liquid stage. The stream may then be processed through a sorbent bed to effectively remove the sulfur compounds.

Multi-stage sulfur removal system and process for a fuel system

A hydrogen generation system is disclosed that includes an integrated steam reforming reactor. The reactor has an overall cylindrical shape, receives a reformate and separately receiving a combustion gas mixture. The reactor includes a plurality of reforming stages arranged in a stacked series of disc shaped stage configuration, wherein each reforming stage has a disc shaped combustion portion adjacent a disc shaped catalyst pack through which the reformate passes, wherein the reformate is directed axially between stages and radially within each stage; and the combustion mixture is directed radially between groups of stages and circumferentially within each stage.

A method of producing short chain alcohols from glycerol generated as a byproduct of biodiesel production is provided.

Gas phase process for monoalcohol production from glycerol

A hydrogen generation system is disclosed that has a vaporization section receiving and vaporizing fuel along with water and passing the vapor to a reformer catalyst section heated by a combustor section which generates reformate gas and is fueled by off-gas from a Hpurification unit along with a combustion air source. The off-gas outlet feeds the combustor section in the reformer assembly to heat the catalyst section and the vaporization section. An Hstorage unit connected to the Hpurification unit pure Houtlet receives the pure H. The storage unit has an outlet selectively connectable to the reformer assembly process inlet during startup without the need for a spark igniter. The startup process includes generating heat in the combustor section of the reformer assembly by passing Hfrom the Hstorage unit through the vaporization section, the reformer catalyst section, the Hpurification unit and through the off-gas connection to the combustor section, then introducing water and fuel through the vaporization section and reformer catalyst section to generate reformate gas when the system is warmed, passing the reformate gas through the Hpurification unit to the off-gas connection to the combustor section, and establishing a back pressure on the reformer catalyst section and vaporizer section to decrease the hydrogen flow from the Hstorage unit until the system is fully sustainable without addition of Hfrom the Hstorage unit.

The thermal reformer system () is provided that compromises a planar assembly including a reformer zone (), a combustion zone (), and various inlet and outlet manifolds with associated fluid flow passages (). The reformer system further compromises an inlet combustion fluid flow passage () connecting an inlet combustion fluid manifold () and the combustion zone (), and an outlet combustion fluid flow passage () connecting the combustion zone () and the outlet combustion fluid manifold (). In the thermal reformer system the heat transfer and recuperation from outlet fluid flows is efficiently transferred to inlet fluid flows, in order to minimize heat loss and insulation requirements.

Methods and apparatus for the production of biodiesel are provided. The methods involve converting a fatty acid rich material to biodiesel using a homogeneous catalyst, followed by electrodialysis of the resulting product to remove the catalyst.

Biodiesel production method and apparatus

A hydrogen generation system is disclosed that includes a fuel reforming reactor generating a hydrogen-rich reformate gas at a temperature greater than 150 C, a pressure swing adsorption (PSA) hydrogen purification unit that separates the reformate gas into a relatively pure hydrogen stream and an off-gas stream, and a catalytic reactor down stream of the PSA unit that converts carbon monoxide (CO) and hydrogen (H) contained in the relatively pure hydrogen stream into methane (CH) and water vapor (HO). The method of purification involves generating a hydrogen-rich reformate gas at a temperature greater than 150 C in a fuel reforming reactor, separating the reformate gas into a relatively pure hydrogen stream and an off-gas stream in a pressure swing adsorption (PSA) hydrogen purification unit, and converting carbon monoxide (CO) and hydrogen (H) contained in the relatively pure hydrogen stream into methane (CH) and water vapor (HO) in a catalytic reactor down stream of the PSA unit. The hydrogen can be further purified by including a secondary purification stage downstream of the PSA unit and the catalytic reactor wherein the secondary purification stage has a water adsorbent material bed that adsorbs the water vapor HO and a hydrogen absorbent material downstream of the water absorbent material that absorbs hydrogen gas preferentially, thus concentrating the non-hydrogen components, such as CH, into an exhaust stream that exits the bed, wherein the absorbed hydrogen gas is then desorbed to create an exiting very pure hydrogen stream.

Hydrogen purification process and system

A system for producing an auxiliary fuel stream containing a low concentration of sulfur compounds from a primary fuel stream includes a first separation stage to separate a portion of a primary fuel stream into a first vapor permeate stream and a first retentate stream, a first separation stage partial condenser connected to the first vapor permeate stream condensing a portion of the first vapor permeate stream into a first liquid stage stream and a first vapor stage stream, and a second separation stage partial condenser condensing a portion of the first vapor stage stream into a second liquid stage. The first vapor permeate stream is preferable sent through a vapor phase reactive desulfurization catalyst reactor to condition any sulfur compounds present into species that can be easily separated from the fuel stream. The process includes isolating a first vapor permeate stream and a first retentate stream from a primary fuel stream by passing a portion of the primary fuel stream through a first membrane separation stage, condensing a portion of the first vapor permeate stream in a first separation stage partial condenser into a first liquid stage stream and a first vapor stage stream, and passing the first vapor stage stream through a desulfurization reactor. The stream may then be processed through a sorbent bed to effectively remove the sulfur compounds.

Multi stage sulfur removal system and process for an auxiliary fuel system

A process and system for separating a fuel stream containing a low concentration of sulfur compounds from a primary fuel stream is disclosed. The process includes isolating a stage-one permeate stream and a stage-one retentate stream from the primary fuel stream, evaporating the stage-one permeate stream at a vacuum, and isolating a stage-two permeate stream and a stage-two retentate stream from the stage-one permeate stream. The stage-two retentate stream is a fuel stream containing low concentrations of sulfur compounds. The system includes a fuel supply, a stage-one separator for separating a fuel stream into a stage-one permeate stream and a stage-one retentate stream, a stage-two separator, a first supply line connecting a portion of the fuel supply to the stage-one separator, and a second supply line connecting the stage-one separator permeate stream to the stage-two separator. The stage-two separator isolates the stage-one separator permeate stream into a stage-two permeate stream and a stage-two retentate stream.
