Split-shell fractionation columns and associated processes for separating aromatic hydrocarbons |
摘要 |
Split-shell fractionation columns and associated processes for separating aromatic hydrocarbons are provided by using, a split-shell fractionation column includes a housing shell having a first height and a partition having a second height and disposed within the housing shell. The partition includes first and second vertically oriented baffles separated by a gap region, a seal plate connecting top ends of the baffles, a first input port formed to extend through the partition for the introduction of a gas into the gap region, and a first output port formed to extend outwardly from a bottom of the gap region and through the housing shell. The partition defines a first distillation zone and a second distillation zone within the housing shell. |

1. A process for separating aromatic hydrocarbons, comprising the steps of:
introducing a first stream comprising a plurality of aromatic hydrocarbons into a first distillation zone of a split-shell fractionation column; introducing a second stream comprising a plurality of aromatic hydrocarbons into a second distillation zone of the split-shell fractionation column, the first and second distillation zones being defined by a partition within the split-shell fractionation column, the partition having a gap region therein; separating the first stream into a first overhead product and a first bottom product, wherein the first bottom product comprises a first liquid that collects at a bottom portion of the first distillation zone; separating the second stream into a second overhead product and a second bottom product, wherein the second bottom product comprises a second liquid that collects at a bottom portion of the second distillation zone; draining the first liquid, the second liquid, or a combination thereof in the gap region through a first outlet port. |
