Optimization and Improvement of Hydrogen System in Refinery and Effect Analysis
Optimal utilization of hydrogen energy is one of the important ways for petrochemical enterprises to achieve the goal of carbon peaking and carbon neutrality goals".Taking the existing ten-million-ton refinery as an example,combining the quality and pressure of hydrogen supply in the refinery,according to the principle of hydrogen grading and mass utilization,the optimization scheme of hydrogen pipeline network is given.According to the CO2 emission calculation model of the hydrogen production unit,the carbon emission of the hydrogen production unit before and after the optimization of the hydrogen pipeline network is estimated.After optimization,the cost of the enterprise can be saved by 25.6053 million yuan per year,and the carbon emission can be reduced by 94 100 t/a.
