Process for quenching a gas obtained by thermal cracking of hydrocarbons
Abstract
Abstract PROCESS FOR QUENCHING A GAS OBTAINED BY THERMAL CRACKING OF HEAVIER HYDROCARBONS THAN KEROSENE WHICH COMPRISES QUENCHING INDIRECTLY THE HIGH TEMPERATURE CRACKED GAS IN A QUENCHING HEAT EXCHANGER TO A TEMPERATURE CRACKED REPRESENTED BY THE FOLLOWING EQUATION: T=0.56X+A WHEREIN T IS A VOLUMETRIC AVERAGE BOILING POINT OF THE FEED HYROCARBONS AND T= T10+T30+T50+T70+T90/5 IN WHICH T10, T30, T50, T70 AND T90 IS A TEMPERATURE OF (*C.) AT WHICH 10 VOLUME PERCENT, 30 VOLUME PERCENT, 50 VOLUME PERCENT, 70 VOLUME PERCENT AND 90 VOLUME PERCENT OF FEED HYDROCARBONS IS DISTILLED IN ASTM DISTILLATION, RESPECTIVELY, AND A IS A TEMPERATURE IN THE RANGE OF 340-240* C., AND T IS A TEMPERATURE ABOUVE 450* C. BUT NOT EXCEEDING 600*C., SAID TEMPERATURE (T) BEING A TEMPERATURE OF THE CRACKED GAS AT AN OUTLET OF THE QUENCHING HEAT EXCHANGER, AND FURTHER QUENCHING DIRECTLY THE CRACKED GAS TO A TEMPERATURE OF 150-250*C.BY SPRAYING HEAVIER OIL.
