PROCESS FOR HEATING REGENERATION GAS

Disclosed is a process for combusting dry gas to heat the air supplied to an FCC regenerator to increase its temperature and minimize production of undesirable combustion products. Preferably, the dry gas is a selected FCC product gas. Alternatively or additionally, dry gas from an FCC product strea...

Beschreibung
Zusammenfassung:	Disclosed is a process for combusting dry gas to heat the air supplied to an FCC regenerator to increase its temperature and minimize production of undesirable combustion products. Preferably, the dry gas is a selected FCC product gas. Alternatively or additionally, dry gas from an FCC product stream is separated and delivered to an expander to recover power before combustion. Se revela un proceso y dispositivo para quemar gas seco, para calentar al aire suministrado a un regenerador FCC para incrementar su temperatura y minimizar la producción de productos de combustión indeseables. Preferiblemente, el gas seco es un gas de producto FCC seleccionado. Alternativa o adicionalmente, el gas seco de una corriente de producto FCC se separa y suministra a un expansor para recuperar energía antes de la combustión.
