Process for converting oxygenates to olefins with direct product quenching for heat recovery

   
   

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.

A invenção atual relaciona-se a um processo para converter um oxygenate em um feedstock aos olefins em um effluent olefin-contendo. O calor é transferido do effluent ao feedstock. O effluent é extinguido então para dar forma a uma fração clara do produto e a uma fração pesada do produto. A fração pesada do produto fractionated para dar forma a um plurality das hastes fractionated, ao menos um de que é usado aquecer o feedstock.
