Abstract: As a clean fossil energy, the application of natural gas in refining enterprises can not only reduce environmental pollution and greenhouse gas emissions, but also improve energy utilization efficiency and economic benefits of enterprises. Meanwhile, the effective utilization of natural gas in refining enterprises plays an important role in promoting the sustainable development of the industrial chain. In addition to being used as fuel, optimizing the utilization of deep processing routes can improve energy efficiency, reduce production costs, and enhance efficiency. This article compares and analyzes three natural gas utilization routes to produce hydrogen,carbon monoxide or acetylene in refining enterprises, studies countermeasures through application examples, and puts forward relevant suggestions on how to further tap the potential of natural gas utilization and enhance its value in the future.

Key words: natural gas, hytrogen production, carbon monoxide, acetylene
