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.
