The present invention additionally provides a method of retrofitting an existing methanol synthesis gas plant which is suitable for carrying out the method of preparing methanol synthesis gas according to the first aspect of the invention.
Description
The present application relates to the production of methanol synthesis gas. More particularly, the present invention utilizes carbon dioxide that is introduced into two reforming stages with the hydrocarbon feedstream.
The production of synthesis gas (e.g. for methanol synthesis) from natural gas feed is typically carried out by steam reforming or a combination of steam reforming and oxygen reforming.
The main reactions of steam reforming (given for methane) are:
CH4 + H2O ⇆ 3H2 + CO
and oxygen conversion (given for methane):
CH4 + ½O2 ⇆ 2H2 + CO
other hydrocarbons react similarly. Any conversion is typically accompanied by a water gas shift reaction:
CO + H2O ⇆ CO2 + H2
the sequential implementation of steam reforming (also known as SMR) and oxygen reforming (also known as autothermal reforming or ATR for short) is known as two-stage reforming.
More details of steam reforming and two-step reforming can be found in the literature.
The product gas from the two-step reforming contains hydrogen, carbon monoxide and carbon dioxide, as well as other components, typically including methane and steam.
The methanol synthesis gas preferably has a so-called modulus (module) (M = (H)) corresponding to 1.90-2.20 or more preferably slightly above 2 (e.g. 2.00-2.10)2-CO2)/(CO+CO2) Composition of).
The two-step conversion yields the preferred stoichiometric modulus described above.
In the chemical industry, there is an increasing desire to reduce carbon dioxide emissions and/or to utilize carbon dioxide as a feed or a portion of a feed in the production of chemical products.
In existing or newly built methanol plants that employ or are designed with two-step reforming in the preparation of methanol synthesis gas, the use of carbon dioxide as at least a portion of the reforming feed is not an option because the addition of carbon dioxide to the reforming process is limited or impossible due to the two-step reforming to produce a stoichiometric correct synthesis gas for methanol production.
We have found that a process for the production of methanol synthesis gas from carbon dioxide by combining a two-step reforming with a hydrogen production step arranged in parallel to the two-step reforming allows the use of carbon dioxide as a part of the feed in a methanol plant based on a two-step reforming.
Accordingly, in one aspect, the present invention provides a process for the preparation of methanol synthesis gas comprising the steps of:
(a) providing a first feed stream comprising a hydrocarbon and steam;
(b) providing a second feed stream comprising carbon dioxide in an amount resulting in a carbon dioxide/hydrocarbon ratio of between 01 and 0.8, preferably between 0.15 and 0.7, when the second feed stream is mixed with the first stream;
(d) introducing the first stream and the second stream into a two-step steam reforming stage comprising a steam reforming step and an autothermal reforming step;
(e) discharging a first syngas stream;
(f) providing a third feed stream comprising hydrogen; and
(g) the first synthesis gas stream is used with the third feed stream as methanol synthesis gas.
The term "methanol synthesis gas" as used above and in the following description and claims is to be understood as any gas that may be used for methanol synthesis, such as make-up gas or unconverted methanol synthesis (gas) that is recycled to the methanol reactor in the methanol loop.
Thus, in one embodiment of the present invention, in step (d), the first feed stream and a portion or all of the second feed stream are mixed upstream of the steam reforming step.
In further embodiments, a portion or all of the second stream is added to the converted first stream upstream of the autothermal conversion step.
In one embodiment, the third stream comprising hydrogen is provided by one or more of:
(a) steam reforming of a stream comprising hydrocarbons and steam arranged in parallel to a two-step reforming process;
(b) electrolyzing water;
(c) an external source.
In one embodiment, in (a) a further stream comprising carbon dioxide is added to the stream comprising hydrocarbons upstream of the steam reforming.
In yet another embodiment, a further stream comprising carbon dioxide is added to the third stream comprising hydrogen.
In one embodiment, in step (d), the second feed stream comprising carbon dioxide is added to the first feed stream prior to the steam reforming step or to the feed stream leaving the reforming step.
In one embodiment, a further stream comprising carbon dioxide is added to the third stream comprising hydrogen.
In one embodiment of the invention, the modulus M of the first synthesis gas<2.3, preferably 1.4<M<2.15, wherein M is (H)2-CO2)/(CO+CO2)。
In one embodiment of the invention, the modulus M in the third stream comprising hydrogen is greater than the modulus M in the first syngas.
In one embodiment of the invention, the modulus M of the third stream comprising hydrogen is >1.9, preferably > 2.0.
In one embodiment of the invention, a first syngas stream and a second syngas stream with optional addition of CO2The modulus M of the mixture of the third stream of (a) is between 1.8 and 2.3.
In one embodiment of the invention, the carbon dioxide in the second feed stream or the further stream comprising carbon dioxide added to the third feed stream is obtained from a flue gas or an off-gas.
In one embodiment of the invention, the steam reforming process is carried out in a tubular reformer, a bayonet (bayonet tube) reformer or a convection reformer.
In one aspect of the inventionIn an embodiment, the first syngas stream and with optional addition of CO is subjected to a further step2The third stream of (a) is converted to a methanol product.
Suitable reforming catalyst compositions for use in steam reforming depend on the amount of carbon dioxide added to the feed and the type of reformer used in the steam reforming. In most cases, a nickel catalyst is sufficient, but some types of steam reformers may require a precious metal catalyst due to the high carbon dioxide content in the feed.
The carbon dioxide for use in the process according to the invention may advantageously be obtained from flue gas or exhaust gas, for example flue gas originating from a burner in a steam reformer.
Depending on the feed composition, it may be preferred to desulfurize and pre-convert the first feed upstream of the two-step reforming and/or desulfurize and pre-convert the second feed upstream of the steam reforming.
The advantages of the method according to the invention are, inter alia: reducing energy consumption and reducing the carbon dioxide footprint.
Another advantage is that the process of the invention allows the production of a more reactive synthesis gas for methanol production than typical gases with a modulus close to 2 resulting from a two-step conversion. The higher reactivity makes the methanol synthesis reaction travel faster and therefore requires less reactor volume and catalyst.
As already mentioned above, the present invention can additionally be used to increase the capacity of an existing methanol plant based on a two-step conversion in the production of methanol synthesis gas. With the possibility of generating more reactive gases, the present invention opens up the possibility of being able to increase methanol production without having to add additional methanol synthesis reactor volume and catalyst or at least with a smaller volume than without the present invention.
Accordingly, a further aspect of the invention is a method for retrofitting an existing methanol synthesis gas plant, comprising:
adding a steam reformer section and/or an electrolysis unit and/or a line to an external source of hydrogen in parallel to the existing two-step reforming section;
connecting the existing two-step steam reforming section to a line connected to a carbon dioxide source and optionally connecting the added steam reformer section and/or electrolysis unit and/or a line connected to an external source of hydrogen to a line connected to a carbon dioxide source; and
the outlet line of the existing two-step reforming section is connected to a methanol synthesis plant with the addition of a steam reformer and/or an electrolysis unit and/or the outlet line of a pipeline hydrogen source.
The two outlet lines may be combined prior to connection or may be connected separately.
