What causes the temperature to drop significantly after gasoline is mixed with feed oil and hydrogen?

The hydrogen feed rate is very low, at 580 Nm/h, yet it manages to lower the temperature of the crude oil (92 t/h) by 20°C. Based on the specific heats of hydrogen and crude oil, the temperature of the crude oil should decrease by less than 1°C. Why is the actual temperature drop so much larger? I would appreciate advice from those with more experience.
Could you be more specific about this parameter? Raise the temperature of both the feed oil and hydrogen
The dissolution of hydrogen in oil is endothermic
The hydrogen temperature is the ambient temperature; it is currently 10°C. The feed oil temperature is 127°C℃
But after mixing, the temperature dropped to 110℃
The original poster can list the data for this section along with that of the downstream heat exchange section; perhaps there is an error in the downstream calculations
Is this selective hydrogenation of certain parts?
