The optimal utilization of Jinan refining and chemical hydrogen resources has achieved practical results

Recently, the hydrogen source of Jinan Refining and Chemical Company's 1.
8 million tons/year catalytic gasoline adsorption desulfurization unit was switched to low gas content, the octane loss of gasoline was reduced by an average of 0.
2, the nitrogen oxide content of flue gas was reduced by 20 mg/cubic meter, and the unit steam consumption of the device was reduced by about 4 kg of standard oil/ton, and the effect of improving efficiency and reducing consumption and environmental protection was obvious
.

Low gas separation is mainly generated by high-pressure hydrogenation devices such as hydrorefining and lubricating oil hydrogenation, with a hydrogen content of about 80%, and it is directly replenished into the hydrogen pipeline network after normal ammonia, which affects the hydrogen purity
of the hydrogen pipeline network.
Previously, the device used pure hydrogen with a hydrogen concentration greater than 99% as the hydrogen source, which had the problem
of excessive partial pressure of the reaction hydrogen and large loss of octane number in the device.

After the low-separation gas separation 1.
8 million tons/year catalytic gasoline adsorption desulfurization device was improved, the partial pressure of the reaction hydrogen of the device was moderately reduced, the octane number loss of the gasoline was reduced from the original 1.
3 to 1.
1, and the dry gas component of the stable tower of the device was improved
.
After the low-separation gas was changed out of the hydrogen pipeline network, the hydrogen purity of the pipeline network increased by an average of 2.
8 percentage points, the load of the circulating hydrogen compressor of the two sets of hydrogen devices was correspondingly reduced, and the total steam consumption was reduced by about 4 kg of standard oil/ton
