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.
