Has anyone seen the adsorption separation unit for straight-run naphtha?
Thread Content
I would like to consult an expert: our plant is a reforming unit, and we have recently installed an adsorption separation unit for straight-run naphtha. This device is supposed to be used for preprocessing heavy data, but I don’t know its principle. Could someone introduce it?
“What does “for heavy data preprocessing” mean?
Friends, you should have started it by now, right? Is it from Yangzi? The adsorption separation process operates on the same principle as that used in xylene adsorption separation: an adsorbent is utilized to selectively adsorb n- and isoparaffins with different polarities, which are then removed using a desorbent. Normal alkanes are used as feedstock for cracking, while isocycloparaffins and aromatics are used as feedstock for reforming. You can refer to http://www.doc88.com/p-89119056801.html
It’s quite simple: straight-chain alkanes (which are difficult to aromatize) are separated from branched-chain alkanes (which are easier to aromatize) as well as aromatics; the straight-chain alkanes are used as feedstock for ethylene production, while the rest is sent to reforming units. It is a device that significantly increases the aromatic potential of the reformed feedstock
