Sources of nitrogen in catalytic dry gas.
Thread Content
As the title suggests, since there is no nitrogen line in the process, leaks can be ruled out. At 20,000 cubic meters per hour, is a rate of around 18% considered high? The unit uses hydrogenated wax oil as the feed ； Second, are the sources all due to inadequate regeneration and degassing? What are good ways to reduce the amount of nitrogen?
In actual production, plant control amounts to 16%~21%, but this is heavy oil; is yours hydrogenated wax oil? What a wealthy company – is it a state-owned enterprise? Materials of this kind can be used in restructuring processes. There must be some design control parameters in place. As long as there are no significant changes in the materials, the feed rate remains stable, and the operating conditions don’t change much, then the quantity will remain steady without any upward trend, and there should be no major problems
Monitor the CO2 content in the dry gas at the same time to see if there are any changes
1. Check that the nitrogen seal volume of the air compressor unit is too large, as this can cause nitrogen to enter the dry gas. 2. Determine whether there is a possibility of flue gas from the regenerator entering the settler; if they are coaxial, there is a risk of leakage due to perforations
