摘　　要：介绍了氨水冷却除萘塔的结构和在焦炉煤气氨水催化脱硫脱氰工艺中的作用,该塔结构紧凑,不仅节省了设备投资,而且可降低煤气的精制成本。The structure of the naphthalene scrubber with flushing liquor cooling and its function in the process for H_2S and HCN removal from COG by flushing liquor catalysis are described. The scrubber has a compact structure. This not only saves the equipment investment, but also reduces the refining cost of the gas.
