Petroleum refining is a core pillar industry of the national economy, with core processes including atmospheric and vacuum distillation, catalytic cracking, hydrorefining, hydrocracking, catalytic reforming, hydrogen production, etc. Hydrogen, as an indispensable process gas, by-product energy, and key carrier for environmental protection and emission reduction in the refining process, runs through the entire production process. Whether it is the by-product hydrogen recovery of catalytic reforming process, desulfurization and pollution reduction of hydrogenation refining, or safety prevention and control of hydrogen storage and transportation, accurate and real-time monitoring of hydrogen concentration is indispensable.
