Abstract: Described herein are methods and systems for producing methyl t-butyl ether (MTBE) by reacting an isobutene-containing stream with methanol in an MTBE production unit. In accordance with the method described herein, at least a portion of the isobutene-containing stream is obtained from a mixed C4 stream from a steam cracking unit and is not produced by passing the dehydrogenation of isobutane. Furthermore, an alkane-containing stream from the MTBE production unit is used as a feed stream for the steam cracking unit.
