ABSTRACT:
As hot crude coke oven gas is conveyed from coke ovens to a position of utilization, condensation of higher hydrocarbons from the coke oven gas is prevented by increasing the temperature of the coke oven gas to a temperature such that higher hydrocarbons are prevented from condensing therefrom. This increase in temperature may be achieved by injecting oxygen-containing gas into the hot crude coke oven gas, to thereby produce a partial combustion of the coke oven gas. Alternatively, when the coke oven gas is being conveyed to a thermal cracking reactor wherein the coke oven gas is thermally cracked to form a cracked gas, the temperature of the coke oven gas may be increased by passing the coke oven gas through a heat exchanger in indirect heat exchange relation with the cracked gas.
