This report presents the feasibility analysis of an on-purpose Ethyl tert-Butyl Ether (ETBE) production plant from butane and ethanol in the United States. Initially, n-butane is isomerized to isobutane, which is then subjected to a dehydrogenation, yielding isobutylene. In the final step, generated isobutylene and ethanol react leading to the formation of ETBE. These steps are similar to Butamer, Oleflex and Ethermax processes in sequence.
This study presents an economical analysis of Ethyl tert-Butyl Ether (ETBE) production from FCC C4 raffinate and ethanol using a process similar to UOP's Ethermax process for isobutylene etherification in China. In this process, the etherification reaction of isobutylene from FCC C4 raffinate stream with ethanol is conducted in two steps, the first step being in a conventional reactor and the second in a reactive distillation column.
This study presents an economical analysis of Ethyl tert-Butyl Ether (ETBE) production from isobutylene and ethanol in the United States. In this process, isobutylene obtained from a butane hydrogenation plant is submitted to a etherification reaction with ethanol conducted in two steps. The first step is in a conventional reactor and the second in a reactive distillation column.
This study provides an economical analysis of Ethyl tert-Butyl Ether (ETBE) production from a raffinate-1 stream and ethanol using a process similar to UOP's Ethermax process for isobutylene etherification in China. In this process, isobutylene from raffinate-1 is submitted to etherification with ethanol in a conventional reactor and in a reactive distillation column.
