Hydrogenation reaction problems in benzene hydrogenation unit
Thread Content
In the main hydrogenation reactor of the crude benzene hydrogenation unit, during the normal production process, the reaction temperature difference has increased, especially in the first and second layers. What are the reasons that cause the reaction temperature difference to increase? ? ? Thanks! ! !
The reactor inlet temperature is too high, causing the side reactions in the main reactor to intensify
The amount of soft water injected is too small, causing pipeline blockage, the polymerization reaction is aggravated and exothermic, and the amount of hydrogen is too sufficient, the reaction is too violent and exothermic.
