Method and plant for generating a synthesis gas which consists mainly of carbon monoxide and hydrogen and has been freed of acid gases, proceeding from a hydrocarbonaceous fuel, and air and steam, wherein low-temperature fractionation separates air into an oxygen stream, a tail gas stream and a nitrogen stream, wherein the tail gas stream and the nitrogen stream are at ambient temperature and the nitrogen stream is at elevated pressure, wherein the hydrocarbonaceous fuel, having been mixed with the oxygen stream and steam at elevated temperature and elevated pressure, is converted to a synthesis gas by a method known to those skilled in the art, and wherein acid gas is subsequently separated therefrom by low-temperature absorption in an absorption column, wherein the nitrogen stream generated in the fractionation of air is passed through and simultaneously cooled in an expansion turbine and then used to cool either the absorbent or the coolant circulating in the coolant circuit of the compression refrigeration plant.

Method and plant for generation of synthesis gas

Method and plant for generation of synthesis gas, comprising the steps of air fractionation to give oxygen, nitrogen and tail gas, gasification of a hydrocarbonaceous fuel to give crude synthesis gas and cleaning of the crude synthesis gas by removal of acid gas by means of cryogenic absorption, wherein the absorbent is cooled by means of a compression coolant circuit and the cooling water used is cooled by evaporative cooling by means of the tail gas obtained in the air fractionation.

Plant and method for generation of synthesis gas

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

This invention relates to the production of synthesis gas by partial oxidation of liquid or gaseous, carbonaceous fuel in the presence of an oxygen-containing oxidant, wherein the fuel, the oxidant and a moderator are separately supplied to a burner and wherein the fuel and the moderator are mixed in a mixing chamber of the burner, before they are brought in contact with the oxidant. To reduce the load of the burner in particular during operation with transient conditions, the oxidant is centrally introduced through an outlet opening of the burner into a combustion chamber and the mixture of fuel and moderator is introduced through the outlet opening into the combustion chamber concentrically around the oxidant.

Process and burner for producing synthesis gas

A method for producing methanol from a synthesis gas containing hydrogen and carbon oxides with a high content of inert components includes passing the synthesis gas through a synthesis reactor so as to catalytically convert a part of the carbon oxides to methanol. The methanol is separated from the obtained mixture from the reactor. The mixture liberated from methanol is separated into a cycle stream and a purge stream. The cycle stream is recirculated so as to form a synthesis circle and combined with a fresh gas stream including hydrogen and carbon oxides before being charged into the synthesis reactor. The purge stream is supplied to a secondary reactor so as to catalytically convert a further part of the hydrogen and carbon oxides to methanol. Further methanol is separated the obtained mixture including synthesis gas, inert components and methanol vapor.

Method and plant for the production of methanol

In a process for producing hydrocarbonaceous educts, the starting material is autothermally gasified by non-catalytic partial oxidation by adding oxygen-containing gas and hydrogen at temperatures of 1200 to 1500&#xb0; C. and pressures of 15 to 100 barto obtain a raw gas containing Hand CO as main components as well as the components CO, HO, CHand traces of HS, COS, CH, Nand Ar, and subsequently the CO contained in the raw gas is converted to COand further Hby adding steam. An improvement of the process consists in that in a pressure-swing absorption process the converted raw synthesis gas is separated directly, i.e. without passing through a wash for removing COand HS, into high-purity Hand into a gas mixture containing HS, CO, H, CO, CH, Ar and N, the gas mixture is supplied to the tail gas wash of a Claus process, the HS separated is introduced into the feed gas of the Claus process, and the waste gas of the tail gas wash, mixed with the tail gas of the Claus process, is burnt.
