Problems of hydrogen heating in selective hydrogenation of gasoline
Thread Content
I would like to ask those who are familiar with this process: Is it necessary to preheat the hydrogen used for selective hydrogenation to a temperature similar to that of the feed oil? The flow rate of hydrogen is quite low compared to that of gasoline, so the heat absorbed should be minimal; is it really necessary to preheat it first?
No preheating is required; the hydrogen mixing point is at high conversion
Hydrogen can be mixed in front of the heat exchanger; the flow rate of hydrogen is very low
