USE OF LOW PRESSURE DISTILLATE AS ABSORBER OIL IN A FCC RECOVERY SECTION

摘要

Process for the recovery of gaseous products from the product mixture obtained by contacting a hydrocarbon feed with a catalyst in a fluid catalytic cracking process, wherein the liquid, obtained by separating the top product of main fractionator into gaseous and liquid fraction, when supplied to the absorber has a temperature of between 8-25 DEG C. This liquid may be presaturated with gaseous top product from absorber; or also a high boiling fraction (cat craker naphtha/light cycle oil) may be first separated from this liquid by distillation.
