| titleOfInvention | The device of thiophene is extracted before coking crude benzene hydrogenation |
| abstract | Extract the device of thiophene before the utility model discloses coking crude benzene hydrogenation, device comprises crude benzol cut cutter unit, extracting rectifying unit, thiophene refined unit.Adopt partitioned column by de-for benzene gently together with de-heavy two pre-separation PROCESS COUPLING, then reclaim the thiophene in benzene by extraction fractional distillation, crude benzol cut cutter unit adopts partitioned column technology, the thick purified petroleum benzin of side take-off on the right side of dividing plate; Extracting rectifying unit adopts side line tower technology, the thick thiophene of side line overhead extraction; Thiophene refined unit is batch fractionating tower; Optimize existing benzene hydrogenation process flow process, reduce hydrogen consumption, obtain purity more than 99.6% thiophene, and thiophene content in benzene is reduced to less than 0.1%, can be the hydrogen usage of follow-up benzene hydrogenation process saving about 50%.The utility model technical process is simple, facility investment is little, energy consumption is low, greatly reduces the generation of hydrogenation byproduct hydrogen sulfide, significantly improves economic benefit and the environmental benefit of crude benzole hydrogenation manufacturing enterprise. |
