  • DIVIDING WALL COLUMN IN ALKYLATION PROCESS FOR REACTOR RECYCLE AND PRODUCT SEPARATION
    Publication number: 20230127377
    Abstract: 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 a fluid catalytic cracking gas plant for naphtha absorption, stripping, and stabilization service
    Patent number: 11236277
    Abstract: 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.
