The present invention relates to integrating a hot oxygen burner with an auto thermal reformer of reducing in a system for generating synthesis gas.

Integration of a hot oxygen burner with an auto thermal reformer

The present invention is directed to a method and system of purifying hydrogen supplied from a storage cavern, particularly to removing methane and other hydrocarbons from the hydrogen withdrawn from the cavern by using selective adsorption. The adsorbed impurities can be removed from the adsorbent by increasing the temperature, reducing the pressure, or a combination of both.

Method of purifying hydrogen supplied from a storage cavern

The present invention provides for a pressure swing adsorption (PSA) process for the substantial removal of HO and COfrom a synthesis gas to obtain a multicomponent product gas substantially free of HO and COwith high recovery of the product gas. Further, the present invention provides an integrated process that achieves sufficiently high Hand CO recoveries such that compression and recycling of the syngas purification PSA tailgas is not necessary to be economically advantageous compared to the conventional processes.

Process for purifying a synthesis gas

The present invention relates to a cold box cycle which allows for independent control of the heat supplied for reboilers associated with the separation columns. More specifically, the invention relates to the tight control of the hydrogen removal separation, thus avoiding the possibility of excess reboiling in this separation. Optimal reboiling also results in a lower temperature of the hydrogen depleted liquid from this separation. As this stream is used to provide a portion of the cooling at the cold end of the primary heat exchanger, lower temperatures facilitate cooling of the incoming syngas feed, reducing carbon monoxide (CO) losses into the crude hydrogen stream from the high pressure separator. Lower CO in the crude hydrogen allows for smaller hydrogen purification equipment.

A top-fired reformer box is provided. The top-fired reformer box includes a burner row, a tube row, a reformer tunnel including a closed end, an open end, and a plurality of tunnel ports formed along a side wall of the reformer tunnel, the plurality of tunnel ports including a one or more tunnel port located along the side of the tunnel, and a flow resistor positioned at least one tunnel port applying a flow resistance for flue gas entering the reformer tunnel via the at least one tunnel port such that uniform flow is achieved within the reformer tunnel.

Organic sulfur compounds contained in refinery off gas streams having either high ort low concentrations of olefins are converted to hydrogen sulfides which can be then be removed using conventional amine treating systems. The process uses a catalytic reactor with or without a hydrotreater depending on the olefin concentration of the off gas stream. The catalytic reactor operates in a hydrogenation mode or an oxidation mode to convert a majority of organic sulfur compounds into hydrogen sulfides.

Process for sulfur removal from refinery off gas

The present invention relates to a method for conditioning a soot-containing syngas stream in a single integrated apparatus containing a scrubbing vessel wherein particulate matter is decoupled from the waste water stream.

Integrated process and unit operation for conditioning a soot-containing syngas

The present invention relates to a method and system for treating a flow back fluid exiting a well site following stimulation of a subterranean formation. More specifically, the invention relates to processing the flow back fluid, and separating into a carbon dioxide rich stream and a carbon dioxide depleted stream, and continuing the separation until the carbon dioxide concentration in the flow back stream until the carbon dioxide concentration in the flow back gas diminishes to a point selected in a range of about 50-80 mol % in carbon dioxide concentration, after which the lower concentration carbon dioxide flow back stream continues to be separated into a carbon dioxide rich stream which is routed to waste or flare, and a hydrocarbon rich stream is formed.

The present invention relates to modifying a reformer tube to facilitate regular tube inspections to assess the service life and subsequently predict its remaining life accurately.

A method and system for producing a synthesis gas in an oxygen transport membrane based reforming system is disclosed that carries out a primary reforming process within a reforming reactor, and a secondary reforming process within an oxygen transport membrane reactor and in the presence of heat generated from a oxygen transport membrane reactor and an auxiliary source of heat. The auxiliary source of heat is disposed within the reactor housing proximate the reforming reactors and may include an auxiliary reactively driven oxygen transport membrane reactor or a ceramic burner.

A method and system for producing a synthesis gas in an oxygen transport membrane based reforming system is disclosed that carries out an air heated pre-reforming process, a primary reforming process, a secondary reforming process.

The present invention provides a method and apparatus for separating air and generating electrical power. A compressed air stream produced in a main air compressor is introduced into an air separation unit that cryogenically rectifies the air into component products. During turndown conditions of the air separation unit, a combustion air stream formed from all or part of the compressed air stream is introduced into a combustor in which a fuel is combusted to produce a heated and pressurized combustion stream. Such stream is introduced to a turbine connected to an electrical generator to generate electrical power. The combustion air stream can be saturated with moisture to increase power output. Further, the combustion air stream can also be preheated with an exhaust of a gas turbine.

The present invention relates a process and apparatus that recovers a helium rich stream from a mixed gas having low concentrations of helium therein. More specifically, the invention relates to an integrated process and apparatus for treating a mixed feed gas from an operating process that produces a liquid product from natural gas containing helium, such as processes that produce ammonia, methanol, or liquid hydrocarbons.

Integrated process and apparatus for recovery of helium rich streams

A method and system for producing methanol that employs steam methane reforming (SMR) and/or autothermal (ATR) synthesis gas production system, together with a partial oxidation system, is disclosed. The dual mode system and method for producing the synthesis gas in a methanol production process optimizes the efficiency and productivity of the methanol plant by using the partial oxidation based reforming system as an independent source of synthesis gas. The disclosed methods and systems are configurable either as a retrofit to existing methanol production facilities or as an integrated package into newly constructed methanol production facilities.
