METHOD OF TREATING COKE GAS TO RECOVER BENZENE HYDROCARBONS AND NAPHTHALENE

摘要

FIELD: coke industry. ^ SUBSTANCE: method consists in cooling of coke gas while simultaneously removing naphthalene from final gas coolers and treating gas in absorber with benzene-rich absorbing oil fed through nozzles into top section of absorber in countercurrent to coke gas moving from bottom upward through leg-supported grid plates. Invention is further characterized by that coke gas is fed into absorber at velocity <= 3.0 m/sec and perforations on grid plates have relative area 0.3-0.6 and are 0.04-0.09 m in diameter. ^ EFFECT: reduced investment and operating expenses. ^ 1 tbl
