Disproportionation and isomerization for isopentane production |
| abstract |
A process for producing isopentane which comprises: (a) disproportionating a normal butane-rich fraction in a C4 disproportionation zone to obtain C3 and n-pentane; (b) disproportionating a normal hexane-rich fraction in a C6 disproportionation zone to obtain n-pentane and C7; (c) fractionating the C3, nC5 effluent and the nC5, C7 effluent to obtain nC5; and (d) isomerizing at least a portion of the normal pentane from both steps (a) and (b) in an isomerization zone to obtain isopentane. It is preferred to further integrate the disproportionation zones with the isomerization zone using common fractionation facilities. |
