Energy consumption for benzene hydrogenation
Thread Content
I read a paper that compared the hydrogenation of crude benzene using Baosteel’s Litol method and the KK method. Based on the data from the K.K. method mentioned there, a rough calculation shows that the energy consumption for hydrogenating 50,000 tons of crude benzene is less than 7,500 MJ per ton of crude benzene; this energy consumption includes hydrogen, coke oven gas, fresh water, electricity, and steam. However, when I asked a company that also uses the K.K. method for crude benzene hydrogenation for their figures, their energy consumption was over 17,000 MJ per ton of crude benzene. Baosteel uses coke oven gas that is purchased from external sources, while this company produces hydrogen from coke oven gas; the difference shouldn’t be that great, right? It’s more than half short. Come here to hear everyone's opinions.
Does no one care about energy consumption? There’s not a single response at all, it’s so sad!
Energy consumption is not important; the overall picture matters. Currently, crude benzene arrives at the plant at around 2550. Pure benzene is around 3,600. A difference of around 1000. I see that the profits are already very small; it’s almost at a loss. . When investing in hydrogenated benzene, it’s important not to be too reckless based on market trends.
Using the same manufacturing process, the direct production costs should be roughly the same. . .

The hydrogenation process for crude benzene is relatively mature, and controlling production costs is a challenge faced by every company. As a result, various companies have made process changes based on their own circumstances – such as switching from triphenyl extraction to diphenyl extraction in order to increase production capacity – as well as other process adjustments aimed at meeting market demands and maximizing their own profits
