| titleOfInvention | A kind of device being prepared benzene and dimethylbenzene by toluene and heavy aromatics |
| abstract | The utility model discloses a kind of device being prepared benzene and dimethylbenzene by toluene and heavy aromatics, reactor is sent into after toluene, heavy aromatics and hydrogen being preheated, product is after cooling, gas phase and liquid phase two streams it is divided in knockout drum, gaseous stream is after low-temperature reformate oil heat exchanger and refrigerator freeze, entering freezing contact tank, the impurity carried in hydrogen after removing reaction, hydrogen uses through compressor boosting Posterior circle.Knockout drum liquid phase stream enters stripper after heat exchange, and stripping tower bottom liquid fraction enters benzene column rectification and obtains benzene, enters back into toluene tower rectification and reclaims toluene and lay equal stress on raw feed；Toluene tower bottom liquid enters benzenol hydrorefining rectification and obtains dimethylbenzene, and heavy aromatics at the bottom of benzenol hydrorefining is delivered to feed(raw material)inlet and again fed.This utility model, on the premise of the concentration maintaining reaction hydrogen and dividing potential drop, decreases the new hydrogen amount of filling into and the impact on subsequent technique, on the basis of obtaining high-purity benzene and dimethylbenzene, it is achieved that toluene and whole recyclings of heavy aromatics. |
