Abstract
The present invention relates to a process for converting an oxygenate in a feedstock to olefins in an olefin-containing effluent. Heat is transferred from effluent to the feedstock. The effluent is then quenched to form a light product fraction and a heavy product fraction. The heavy product fraction is fractionated to form a plurality of fractionated steams, at least one of which is used to heat the feedstock.
