There is proposed a method for pre-reforming a hydrocarbonaceous feed stream into a pre-reforming product containing carbon oxides, hydrogen and hydrocarbons, in which the adiabatically operated pre-reforming reactor comprises at least two reaction zones designed as fixed beds in a common reactor vessel, which are in fluid connection with each other and are filled with beds of granular, nickel-containing catalyst active for pre-reforming, wherein the first reaction zone in flow direction is filled with a catalyst active for high-temperature pre-reforming and the last reaction zone in flow direction is filled with a catalyst active for low-temperature pre-reforming.

Method for pre-reforming hydrocarbons

A novel steam reformer unit design, a novel hydrogen PSA unit design, a novel hydrogen/nitrogen enrichment unit design, and novel processing scheme application are presented.

Steam reformer based hydrogen plant scheme for enhanced carbon dioxide recovery

A reformer tube for producing synthesis gas by steam reforming of hydrocarbon-containing feed gases, preferably natural gas, includes one or more helically coiled heat exchanger tubes which are arranged within a catalyst bed of a reforming catalyst and are helically coiled over part of their length located within the catalyst bed and are otherwise straight are present, where the straight proportion of the heat exchanger tubes and/or the helix pitch of the helically coiled part alters within the catalyst bed and matching to requirements of the pressure drop, the heat exchange properties, and the corrosion resistance.

Reformer tube with internal heat exchange

A safety means for protecting a plant section located on the pressure side of a jet compressor connected with a propellant system against the exceedance of an admissible pressure, comprising a controlled safety valve actuated by external energy, whose control means measures is connected with the plant section to be protected via at least one pressure tapping line, wherein the safety valve is arranged such that upon exceedance of the pressure in the protected plant section it can vent propellant from the propellant system.

Safety means against pressure exceedance

A method for producing a synthesis-gas product gas and a vapor stream includes catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer. The hot synthesis-gas product gas stream is cooled in a heat exchanger to form a cooled synthesis-gas product gas stream and a first partial vapor stream, which is supplied to the product vapor stream. The reforming furnace is operated so as to burn a burner feedstock in burners, cool a hot flue gas stream from the burners in a heat exchanger to form a cooled flue gas stream and a second partial vapor stream, and separate the cooled flue gas stream into a waste gas stream and a flue gas recirculation stream. The flow of the recirculated flue gas is increased with decreasing flow of the synthesis-gas product gas to obtain an approximately constant product vapor stream by increasing the second partial vapor stream.

Method for operating a reformer furnace and reforming plant

In a process for producing synthesis gas by catalytic conversion of hydrocarbons contained in a desulfurized feed gas stream with steam, the mixture of feed gas and steam is preheated by heat exchange at a pressure of 10 to 45 bar to a temperature of 300 to 700&#xb0; C. and is subsequently heated by heat exchange above a catalyst at a pressure of 10 to 45 bar to a temperature of 650 to 950&#xb0; C. To minimize the apparatus involved, it is provided that the mixture of feed gas and steam traverses a catalyst bed contained in a reaction tank, and the catalyst bed is heated by thermal radiation and convection.
