AI Technical Summary

Problems solved by technology

When methanol is produced from natural gas, due to its low carbon-to-hydrogen ratio as a raw material, the carbon-to-hydrogen ratio in the synthesis gas produced from it is unreasonable, resulting in large emissions of synthetic purge gas and serious waste of resources and power

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:...

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical industry. More specifically, the present invention relates to a method for co-producing various chemical products using natural gas, coal and petroleum as raw materials. 【Background technique】 [0002] As we all know, oil, natural gas and coal account for a considerable proportion of the world's mineral energy reserves, and it is of great practical and strategic significance to realize the clean and efficient utilization of the above three natural resources. [0003] According to the traditional petroleum processing method, after the separation process, the petroleum is transformed into gasoline, diesel, heavy oil, paraffin and other products. Valuable gasoline and diesel oil, liquefied petroleum gas, cracked dry gas, petroleum coke and other products. Among them, the content of hydrogen in the cracked dry gas is very high. If it is not used rationally, it will be a very big waste of precious...
