Embodiment
[0090] Example: Use of compressed natural gas as feedstock for part of the synthesis gas source.
[0091] According to this specification, this embodiment figure 1 The described process flow is carried out.
[0092] The composition of the natural gas that this embodiment selects to use (in this natural gas total volume, dry basis) is as follows:
[0093]
[0094] The implementation steps are as follows:
[0095] In the reformer of natural gas reforming system 1, the flow of natural gas entering the reformer is 17540Nm 3 / h, the flow of oxygen (oxygen purity is 99.6%) from the air separation unit 4 is 12278Nm 3 / h, the volume ratio of oxygen to natural gas is 0.7, they react in the natural gas conversion system 1 under the conditions of internal pressure 6.1MPa and temperature 1280℃ to generate a crude synthesis gas with a flow rate of 50000Nm 3 / h, the composition of the crude synthesis gas (based on the total volume of the crude synthesis gas, dry basis) is as follows:...
