Examples
Embodiment 1
[0032] The load of HYCO unit is hydrogen production 6800Nm3 / h, water-carbon ratio 3.619, air excess coefficient 1.24, natural gas flow rate 122Nm3 / h, analytical gas flow rate 4629Nm3 / h, PSA operation factor 0.644, air coefficient required for analytical gas 1.982.
[0033] The calculated oxygen content is 3.11%, the actual 3.15%, and the difference is less than 0.1%. Due to the error of the instrument and other air blowing equipment, it can be determined that the instrument is accurate and the combustion utilization rate is high.
Embodiment 2
[0035] The load of HYCO unit is 16000Nm3 / h hydrogen production, 2.743 water-carbon ratio, 1.3 excess air coefficient, 256Nm3 / h natural gas flow rate, 9136Nm3 / h analytical gas flow rate, 1.05 PSA operation factor, and 2.48 air coefficient for analytical gas
[0036] The calculated oxygen content is 1.738%, the actual 1.64%, and the difference is less than 0.1%. Due to the existence of instrument errors and other blast equipment errors, it can be determined that the instrument is accurate and the combustion utilization rate is high.
Embodiment 3
[0038] The load of HYCO unit is 18786Nm3 / h hydrogen production, 2.723 water-carbon ratio, 1.253 excess air coefficient, 299Nm3 / h natural gas flow rate, 10633Nm3 / h analytical gas flow rate, 1.05 PSA operation factor, and 2.48 air coefficient for analytical gas
[0039] The calculated oxygen content is 1.25%, the actual 1.16%, and the difference is less than 0.1%. Due to the existence of instrument errors and other blast equipment errors, it can be determined that the instrument is accurate and the combustion utilization rate is high.
