Process for the production of a H-containing product in a hydrogen production facility comprising a catalytic steam-hydrocarbon reformer and a pressure swing adsorption unit. The process comprises a catalytic steam-hydrocarbon reformer shutdown mode, a pressure swing adsorption unit shutdown mode, a pressure swing adsorption unit maintenance state, a pressure swing adsorption unit startup mode, and a catalytic steam-hydrocarbon reformer startup mode. The pressure swing adsorption unit startup mode comprises purging the adsorption beds with N, then purging the adsorption beds with H, and then adjusting the pressure of the Hin the adsorption beds to within defined target pressure ranges.

Process for the production of hydrogen

A pressure swing adsorption process for an adsorption system having 12 adsorption beds, the process having a cycle with 5 pressure equalization steps. Background is provided for the various pressure swing adsorption cycle steps.

Pressure swing adsorption process

A process and system for producing a H-containing product gas and purified water from an integrated catalytic steam-hydrocarbon reforming and thermal water purification process. Raw water, such as salt water, is heated by indirect heat transfer with reformate from the catalytic steam reforming process for purifying raw water in one of a multiple effect distillation process and a multi-stage flash process.

Water purification using energy from a steam-hydrocarbon reforming process

A process for producing a hydrogen-containing product gas with reduced carbon dioxide emissions compared to conventional hydrogen production processes. A hydrocarbon and steam are reformed in a reformer and the resulting reformate stream is shifted in one or more shift reactors. The shifted mixture is scrubbed to remove carbon dioxide to form a carbon dioxide-depleted stream. The carbon dioxide-depleted stream is separated to form a hydrogen-containing product gas and a by-product gas. A portion of the hydrogen containing product gas is used as a fuel in the reformer and a portion of the by-product gas is recycled back into the process. The process may optionally include reforming in a prereformer and/or an oxygen secondary reformer.

Steam-hydrocarbon reforming with reduced carbon dioxide emissions

In a process for producing a hydrogen-containing gas, a hydrocarbon feed gas and steam are introduced into a reaction vessel containing a complex metal oxide and steam-hydrocarbon reforming catalyst thereby forming a combustible gas mixture comprising hydrogen. A regeneration gas comprising greater than 0.1 volume % oxygen up to and including 2 volume % oxygen is introduced into the reaction vessel to displace at least a portion of the combustible gas mixture from the reaction vessel. Subsequently, additional regeneration gases may be introduced into the reaction vessel. Numerous means for providing various regeneration gases are presented.

Regeneration of complex metal oxides for the production of hydrogen

A method and apparatus for dispensing compressed gas to a receiving tank is provided where the initial density in the tank is determined, and the quantity of compressed gas to be transferred is calculated and delivered based on the initial density and a desired final density.

Method and apparatus for dispensing compressed gas

This invention is a directed to combustion apparatus incorporating a combustion chamber, a precombustion chamber and a multi-wall burner and a process for effecting combustion of gases, particularly feed gases containing gases that, on combustion, form solid oxidation products, i.e., solid-forming gases. A pathway is formed between the exterior of the precombustion chamber and the interior of said combustion chamber, whereby said pathway permits introduction of a secondary oxidant into the interior portion of the combustion chamber for facilitating combustion of said solid forming gas.

Burner and process for combustion of a gas capable of reacting to form solid products

An oxy-fuel burner is set forth for providing combustion energy to a glass furnace via the mixing and combustion of a fuel stream and an oxidizer stream. The burner is divided into at least two sections, a substantially vertical section beginning at the bottom or feed end of the burner and a generally shorter, substantially horizontal section terminating at the opposite or discharge end of the burner. In a key embodiment, the vertical section of the burner protrudes into the furnace atmosphere through the underside of an air port, while the horizontal section is pointed toward the interior of the furnace. Depending on the number of burners installed, this allows from partial to full conversion of an air fuel furnace to an oxy-fuel furnace. Also, in a key embodiment, the burner includes an oxidant staging means to introduce oxidizer through a staging conduit running beneath and collateral with the outer conduit.

Self-cooling oxy-fuel through-port burner for protruding into glass furnace atmosphere

Method and apparatus for continuation of combustion with an oxy-fuel combustion system when the supply of oxygen is temporally reduced or stopped. Air or oxygen enriched air and fuel are introduced into the device being heated in place of the oxy-fuel mixture to effect combustion and maintain the heating level in the furnace. Water cooling of the furnace gases is used to reduce the volume of exhaust gases when operating in the air or oxygen enriched air mode.

Method and apparatus for backing-up oxy-fuel combustion with air-fuel combustion

A process and furnace for melting glass is set forth wherein the majority of the combustion energy over the melting zone of the furnace is provided by oxy-fuel combustion while a majority of the combustion energy over the fining zone of the furnace is provided by air-fuel combustion. In many cases, it will be preferable to provide greater than 70% and up to and including 100% of the combustion energy over the melting zone by oxy-fuel combustion and greater than 70% and up to and including 100% of the combustion energy over the fining zone by air-fuel combustion. By proper tailoring of the combustion space atmosphere through oxy-fuel and air-fuel firing, the present invention can result in an improvement in glass productivity and quality. The present invention can be applied in the construction of a new furnace or can be applied to existing air-fuel furnaces.

Glass melting process and furnace therefor with oxy-fuel combustion over melting zone and air-fuel combustion over fining zone

Method and apparatus for combusting and/or gasifying a generally viscous liquid or a slurry wherein the liquid or slurry are atomized in a central atomization device within a burner housing the central atomization device using a portion of a gaseous oxidant introduced into the burner to atomize the liquid or slurry as it exits the atomization device.
