    Abstract: A method and a plant for simultaneous production of a gas for injection into an oil field and production of methanol, dimethyl ether and/or other oxygenated hydrocarbons or production of higher hydrocarbons from natural gas is disclosed. An air separation unit (ATR) for production of pure nitrogen for injection and pure oxygen for production of synthesis gas ("syngas") by authermal reformation of a natural gas is an essential part of the method and plant.

    Abstract: A method is described for conversion of natural gas or other fossil fuels to higher hydrocarbons, comprising the following steps: a) reaction of natural gas with steam and oxygenic gas in at least one reforming zone in order to produce a synthesis gas consisting primarily of hydrogen and CO, in addition to some carbon dioxide; b) passing said synthesis gas to a Fisher-Tropsch reactor in order to produce a crude synthesis stream consisting of lower hydrocarbons, water and non-converted synthesis gas; c) separation of said crude synthesis stream in a recovery zone, into a crude product stream mainly containing heavier hydrocarbons, a water stream and a tail gas stream mainly containing the remaining constituents; which is charaterized in that the method also comprises the following steps; d) stream reformation of at least part of the tail gas in a separate steam reformer; e) introduction of the reformed tail gas into the gas stream before this is led into the Fischer-Tropsch reactor.

    Abstract: A method for increasing production in an existing processing plant for converting natural gas into a product, wherein the natural gas is first converted into a synthesis gas in a synthesis gas section, the synthesis gas is reacted in a reactor for synthesis of the product, where non-converted synthesis gas and product are separated into two streams, where a product-ri ch stream is taken out of the process, whilst a product-poor stream is recycled as feed to the reactor together with make-up synthesis gas, and where a portion of the recycle stream is taken out of the recycle loop as a purge ga s, where the purge gas is separated into hydrogen-rich and hydrogen-poor stream s, where hydrogen-rich streams are introduced into steps in the process where i t is desirable to have a supplement of hydrogen, and where the residual therma l value of the hydrogen-poor stream is optionally used for heating before it i s discharged. A modified processing plant for carrying out the method is also described.
