A feed gas comprising CO, HS and His treated to produce an H-enriched product and an HS-lean, COproduct. The feed gas is separated to provide the H-enriched product and a stream of sour gas. The stream of sour gas is divided into two parts, one of which is processed in an HS removal system to form one or more streams of sweetened gas, and the other of which bypasses the HS removal system, the stream(s) of sweetened gas and the sour gas bypassing the HS removal system then being recombined to form the HS-lean, COproduct gas. The division of the sour gas between being sent to and bypassing the HS removal system is adjusted responsive to changes in the HS content of the sour gas, so as to dampen or cancel the effects of said changes on the HS content of the HS-lean, COproduct gas.

Method and apparatus for adjustably treating a sour gas

Sulfur dioxide (SO) is removed from a carbon dioxide feed gas by maintaining the feed gas at elevated pressure(s) in the presence of oxygen (O), water and NOfor a period of time sufficient to convert SOto sulfuric acid and NOto nitric acid and produce SO-depleted, NO-lean carbon dioxide gas. The invention resides in separating the sulfuric and nitric acids from said SO-depleted, NO-lean carbon dioxide gas, and then neutralizing the acids by reaction with an alkaline sorbent in an acid/sorbent reactor system to produce sorbent-derive sulfate. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a carbonaceous fuel.

A combustion system and method for operating a combustion system, such as a furnace or boiler. The method includes providing a burner system having one or more burner elements configured to combust solid fuel and one or more oxygen providing devices configured to introduce oxygen into the near burner zone of one or more burner flames. A sensor is provided and arranged and disposed to measure a flame parameter in the near burner zone of the burner flame associated with one or more the burner elements. The flame parameter is measured with the sensor and an oxygen flow is determined in response to the measured flame parameter. Oxygen flow is introduced to one or more locations in the combustion system with the one or more oxygen providing devices.

Oxygen control system for oxygen enhanced combustion of solid fuels

A method and apparatus for removing carbon dioxide from a synthesis gas stream containing hydrogen is disclosed. The method includes absorbing the carbon dioxide using a physical solvent under high pressure and then liberating the carbon dioxide in a series of expansion stages where the pressure on the solvent is reduced. The expansion ratio increases with each expansion stage. The apparatus includes expansion stages having throttling devices and expansion tanks operated at increasing expansion ratios. Carbon dioxide is liberated in this manner so as to minimize the energy required compress for transport via a pipe line for sequestration of the gas. Sequestration of the carbon dioxide is preferred to atmospheric venting to curb the release of greenhouse gases.

Method and apparatus for separating gases

A steam methane reforming process for producing a hydrogen product while capturing COfrom the process. Steam and a hydrocarbon are reformed in a catalytic reformer. The reformate is separated by pressure swing adsorption to form the hydrogen product and a PSA tail gas. The tail gas is returned to the reformer as a fuel. The fuel is combusted with synthetic air where the synthetic air is formed by combining a portion of the flue gas with industrial grade oxygen. The flue gas consists essentially of COand HO. The HO is condensed out of another portion of the flue gas to form an essentially pure COproduct.

A method of configuration of combustion process control. The method includes providing a combustion system having a plurality of burner elements, a plurality of gas injection points and a controller. The gas injection points are configured to provide a support gas. One or more tasks for operation of the combustion system are determined. A plurality of groupings of the gas injection points are determined for each of the one or more tasks. An individual ranking for each of the plurality of groupings is determined in response to the one or more tasks. A composite ranking of injection points in response to the individual rankings and the controller is configured to operate the plurality of gas injection points in response to the composite ranking. A combustion system and a method for operating a combustion system are also disclosed.

Oxygen control system for oxygen enhanced combustion

A combustion system having a furnace arranged and disposed to receive solid fuel and oxygen and combust the solid fuel and oxygen to form a flue gas. The system includes a heat exchanger arrangement arranged and disposed to receive heat from the flue gas, where the heat exchanger arrangement has a predetermined heat exchange capacity. A water injection arrangement is arranged and disposed to provide water to the flue gas to controllably adjust the flue gas mass flow rate and temperature to provide the predetermined heat exchange capacity.

Combustion system with steam or water injection

A system and method is disclosed for acquiring temperature data from a plurality of features in a chamber including capturing a first image of an interior area of the chamber, capturing a second image of the interior area of the chamber, identifying a plurality of features within the data for the first image and the data for the second image, generating an interior area representation based on the first image data, the second image data, and the identification of each feature of the plurality of features in the interior area, and correlating the interior area representation to temperature information related to the interior area.

System and method for temperature data acquisition

Sulfur dioxide (SO) may be removed from carbon dioxide feed gas by contacting the carbon dioxide at an elevated temperature and an elevated pressure with a catalyst for oxidizing SO, in the presence of oxygen (O) to convert SOto sulfur trioxide (SO); contacting SOin the resultant SO-enriched carbon dioxide gas with water to produce sulfuric acid and SO-depleted carbon dioxide gas; and separating the sulfuric acid from the SO-depleted carbon dioxide gas. If present, NOis also removed from the carbon dioxide feed gas as nitric acid to produce SO-depleted, NO-lean carbon dioxide gas. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a hydrocarbon fuel or carbonaceous fuel, within or downstream of the COcompression train of a COrecovery and purification system.

A feed stream, comprising hydrogen sulphide (HS), carbon dioxide (CO), hydrogen (H) and, optionally, carbon monoxide (CO), is separated into at least a COproduct stream and an Hor Hand CO product stream. The stream is separated using a pressure swing adsorption system, an HS removal system and a further separation system, which systems are used in series to separate the stream. The method has particular application in the separation of a sour (i.e. sulphur containing) syngas, as for example produced from the gasification of solid or heavy liquid carbonaceous feedstock.

Separation of a sour syngas stream

A gaseous mixture, comprising CO, H, HS and optionally CO, is separated into an Hor Hand CO product stream (H/CO product stream), and a COenriched stream containing at least one combustible component selected from HS, H, CO and any additional combustible components present in the gaseous mixture. A support fuel stream, comprising one or more combustible components, is combusted to form a stable flame, and the COenriched stream and flame are contacted in the presence of sufficient Oto combust all or substantially all of the combustible component(s) present in said COenriched stream. A COproduct stream is formed from said combustion effluent. The support fuel stream may be generated from the process of generating or separating the gaseous mixture or from the H/CO product stream. Where the COenriched stream contains HS, the support fuel stream may also be a stream obtained off-site that comprises HS.

Method of treating a gaseous mixture comprising hydrogen, carbon dioxide and hydrogen sulphide

A feed gas comprising CO, HS and His treated to produce an H-enriched product and a COproduct. The feed gas is separated by pressure swing adsorption to provide a stream of the H-enriched product, and two streams of sour gas depleted in Hand enriched in HS and COrelative to the feed gas. One of the streams of sour gas is processed in an HS to elemental sulfur conversion system, in which HS in the sour gas is converted to elemental sulfur order to obtain a stream of sweetened gas, from which the COproduct is formed. The other of said streams of sour gas is processed in an oxidation system, in which HS in the sour gas is oxidized to SO(SOand SO) which is introduced into the HS to elemental sulfur conversion system.

Method and apparatus for treating a sour gas

Sulfur dioxide (SO) is removed from carbon dioxide feed gas comprising SOas a contaminant by maintaining the carbon dioxide feed gas at an elevated pressure in contact with an alkaline sorbent for a period of time sufficient to react said alkaline sorbent with SO. Where NO, oxygen (O) and water are also present, not only is the rate of reaction with the sorbent increased, but also additional SOis removed by conversion to sulfuric acid, and NOis removed as nitric acid. The method has particular application in the removal of SOand NOfrom flue gas produced by oxyfuel combustion of a hydrocarbon or carbonaceous fuel.
