Abstract

A process for producing feedstock from natural gas for use in synthesising methanol, comprises using enriched air produced by a membrane or molecular sieve (11) as the oxidant in a partial oxidation reactor (17) where the enriched air and natural gas are reformed, after which the reformed gas may be modified using molecular sieves (20) and/or further membranes to produce an acceptable synthesis gas. <IMAGE>

Description

METHANOL PRODUCTION PROCESS This invention relates to the production of methanol from natural gas. In particular it relates to the production of methanol in a floating vessel (e.g. a converted tanker) at an offshore location where space and weight are at a premium, and where violent motions may be experienced in storms.
In the present (onshore) state of the art, natural gas is reformed in a tubular steam reformer, the gases are cooled, compressed, and then fed to a methanol production loop.
The invention provides a process for producing feedstock from natural gas for use in synthesising methanol, comprising the steps of using enriched air produced by a membrane or molecular sieve as the oxidant in a partial oxidation reactor where the enriched air and natural gas are reformed, after which the reformed gas may be modified using molecular sieves and/or further membranes to produce an acceptable synthesis gas.
It is preferred that waste nitrogen from the oxygen concentrating membrane or sieve system is expanded through a turbine.
It is further preferred that the waste nitrogen stream is combusted prior to expansion with natural gas or a waste fuel stream derived from a subsequent phase of the process.
Preferably a waste stream from the enriched air separation unit is treated to remove residual oxygen, and then used for injection for enhanced recovery of subsea oil or gas.
Preferably there is no indirect steam raising.
The invention also provides a process for synthesising methanol using a feed stock produced according to any one of the foregoing five paragraphs.
It is preferred that the crude methanol is subsequently refined using a centrifugal distillation facility (e.g. a HYGEE system - Trade name).
The invention also provides plant for effecting the process described above.
The invention includes methanol when produced in accordance with the process or plant described above.
In this invention the disadvantages of the use of the large heavy steam reformer are overcome by using a partial oxidation reactor, fed with enriched air made in a novel way and integrated with the methanol production process. Furthermore, the rejection of nitrogen from the synthesis gas, both from the loop purge and from the loop makeup gas, is also handled in a novel way. Use of membranes or molecular sieves (PSA) to produce feedstock for the methanol loop enables the plant to operate on unstable surfaces, as no gas/liquid systems requiring stable contact are involved.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing which is a flow chart for a 2500TPD methanol plant.
Air is compressed at 10, and passed through a permeable membrane separator 11, and/or through molecular sieves, whereby some of the nitrogen in the air is separated from the oxygen. The nitrogen rich stream is then heated in a furnace 12 and expanded in an expansion turbine 14 to gain shaft power. This shaft power may be used ta supply some of the power to e.g. the air compressor. In order to increase the efficiency of this turbine 14, the waste nitrogen stream can be combusted with natural gas or a waste fuel stream from a subsequent part of the process.
The oxygen rich stream is compressed at 15 and fed, together with natural gas (16), to a partial oxidation reactor 17 wherein the natural gas (largely methane) is reformed to a mixture of gases containing carbon oxides, hydrogen, steam and a small amount of unreformed methane. (The reactor 17 incorporates quench cooling.) This stream is cooled (in 17) and then split into two streams A and B.
One of these streams (A), after adjusting the steam-to-carbon ratio if required, is passed through a carbon monoxide shift reactor 18 in which the carbon monoxide is reacted with steam to form hydrogen and carbon dioxide. This shifted stream is passed through a water separator 19 to a molecular sieve PSA (pressure swing absorber) unit 20 to separate the hydrogen from the other gases present in the stream.
The other stream (B), formed by splitting the effluent from the partial oxidation reactor 17, is cooled at 21 to condense out the water, and is combined at 22 with the hydrogen produced from unit 20 as above. It is then combined with impure hydrogen recovered from the methanol loop purge gas by separator 24.
The combined stream (C) is used as makeup gas to a methanol loop very similar to that conventionally used, except that stream C contains a much higher amount of nitrogen. Because of the higher amount of nitrogen, a much larger purge than is conventionally taken is removed from the loop at 23, and is either combined with the stream fed to the PSA molecular sieve unit 20; or alternatively the hydrogen is concentrated by membrane unit 24 positioned between the loop and the suction of the syngas compressor 25. In this way the nitrogen from the split stream not initially passed through the PSA unit 20 is rejected from the system.
The methanol loop has a compressor, converter and separator (leading to the purge removal at 23), and provides fuel gas and crude methanol as shown. The crude methanol can be refined using a centrifugal distillation facility e.g. a HYGEE system.
The reject streams from the PSA unit 20 and the separator 24 may be used as fuel, e.g. either in a boiler or a gas turbine. The nitrogen rich stream from the enriched air unit may be heated in e.g. the exhaust of a gas turbine used to supply compression power to e.g. the air compressor or to a compressor used to compress the methanol synthesis loop make up gas and/or recycle gases.
