Butene Isomerization

Lummus Technology offers several paths to butane isomerization. CD-DEIB® is a separation technology which combines fractionation and hydroisomerization within one unit operation for the effective and complete separation of isobutene from 1-butenes and 2-butenes. 

The CD-DEIB unit can be combined with Lummus Technology’s C4 skeletal isomerization technologies—ISOMPLUS® and CDISIS®—for the shift to yield either higher isobutene production or higher n-butenes production.


CD-DEIB® Deisobutanizer Process

CD-DEIB® is a separation technology which combines fractionation and hydroisomerization within one unit operation for the effective and complete separation of isobutene from 1-butenes and 2-butenes. The technology produces both an isobutylene concentrate with low n-butenes content and an n-butenes concentrate with low isobutene.
