The integrated debutanizer column may comprise a dividing wall column.

The effluent from the first alkylation system is fed to an interim debutanizer where the C4's are separated from the alkylate product.

An integrated debutanizer column provides an LPG stream, a light naphtha stream and a heavy naphtha stream.

The heavier fractions are stripped and sent to a debutanizer, and the lean oil is recycled back to the absorber-deethanizer.

A process and apparatus that uses a debutanizer with a side stripper can recover a light stream, an intermediate stream and a liquid stream.

Additional dimerization is carried out in a distillation column reactor that acts as a debutanizer to separate the unreacted isobutene form the product and the tertiary butyl alcohol.

A process for treating a full boiling range naphtha is disclosed in which the mercaptans and diolefins are removed simultaneously in a debutanizer distillation column reactor (10).

Any sulfonates or sulfonic esters are removed by hydrodesulfurization or decomposition catalyst in a separate reactor or in either the deisobutanizer (DIB) or debutanizer (DB) column.

C3/C4 is separated from pentanes in the debutanizer, scrubbed to remove hydrogen sulfide, and fed to a splitter where propane and butane are separated.
