A dividing wall column is used in an alkylation process flow scheme to fractionate an alkylate reactor effluent to produce an iso-butane-rich stream as a recycle feed for the alkylation reactor while also separating iso-butane, normal butane and alkylate as separate product streams depending on the reactor effluent composition. In an optional embodiment, the scheme may contain propane.

Dividing wall column in alkylation process for reactor recycle and product separation

Methods and systems for recovering naphtha blend stock from hydrocarbons produced in a fluid catalytic cracking (FCC) process. In particular, the disclosure concerns gas plants for an FCC process, wherein the gas plant uses a dividing wall column. The dividing wall column essentially performs the functions that are performed in a traditional FCC gas plant by three different columns, namely, a primary absorber, a stripper, and a debutanizer.
