A process for the manufacture of synthetic crude oil characterised by (a) mixing natural gas with a recycle stream (the stream from point (f) below) (b) removing acid gas from the mixture (c) partially oxidising the stream from point (b) (d) utilising the stream from point (c) to synthesis crude oil (e) passing tail gas obtained in synthetic crude oil synthesis step (d) through a carbon monoxide shift unit (f) recycling the sifted stream resulting from point (e), to mix with the natural gas as described in point (a) above. e
Description
SPECIFICATION
Manufacture of synthetic crude
This invention relates to the use of natural gas as a feedstockforthe production of synthetic crude oil (syncrude).
Syncrude is a useful product inasmuch as it may be blended with ordinary crude oil and/or processed in ordinary refineries.
There are many places in the world where natural gas is cheap and so it is commercially interesting to use it as a feedstock for syncrude. Often natural gas contains carbon dioxide and other acid gases.
The invention comprises mixing natural gas with a recycle stream and desulphurising it, using an acid gas removal unit such as an amine unit or a Benfield unit, which unit wound also remove any carbon dioxide present in the natural gas, pre-heating the sweetened gas and passing itthrough a guard desulphurisation unit after which the stream goes to a partial oxidation unit, which unit uses oxygen oran oxygen-containing gas to reform the natural gas to crude synthesis gas.
The effluent from the partial oxidation unit is cooled by raising high pressure steam and isfurther cooled to condense out substantially all of the water in the stream. The stream is then fedtothe syncrude unit wherein syncrude is synthesised along with some oxygenates. The tail gas from the syncrude synthesis unit is mixed with steam and passedto a carbon monoxide shift unit in which carbon monoxide is shifted to carbon dioxide and hydrogen and the effluent from this stream is the said recycle stream which is mixed with the natural gas feed upstream of the acid gas removal unit so that excess carbon dioxide may be rejected.
The process may otherwise be described as being characterised by:
a) mixing natural gas with a recycle stream (the stream from pointf below)
b) removing acid gas from the mixture
c) partially oxidising the stream from point b
d) utilising the stream from point cto synthesis crude oit e) passing tail gas from the synthetic crude synthesis unit through a carbon monoxide shift unit
f) recycling the shifted stream resulting from point e, to mix with the natural gas as described in point a above.
Fig. 1 describing the process is aftached.
