摘要:

对煤气脱萘的工艺、设备及能耗进行了研究。介绍了马钢开发的焦炉煤气脱萘新工艺,该工艺在横管初冷器内完成煤气的一步脱萘,煤气净化后不再设置其他脱萘工序。初冷器平均阻力在1 000Pa以下,不用蒸汽清扫初冷器,煤气净化设备未发生萘的堵塞,每年可节约12 000t标准煤,节能效果明显。

Abstract:

The process, equipment and energy consumption of gas naphthalene removal were studied. The new process of coke oven gas naphthalene removal developed by Masteel was introduced, one step naphthalene removal of gas  was completed in cross tube primary gas cooler, after gas purification there was no other naphthalene removal unit. The average resistance of primary gas cooler was below 1 000Pa, primary gas cooler was not cleaned with steam, gas purification equipment was never blocked by naphthalene, 12 000t standard coal can be saved annually, the energy-saving effect was obvious.
