【 摘 要 】

The new method for removal tar from coke oven flue gas by emulsion liquid membrane was developed. The W/O emulsion was prepared by using kerosene as organic solvent, L-113B as surfactant, water as internal phase and external phase, respectively. The optimum operating conditions were obtained: The optimum experimental conditions of the ELM process for initial tar concentration of 62.5 mg/L are: absorption time: 40 min; concentration of L-113B: 4% (v/v); emulsification speed: 4000 r/min; volume ratio of emulsion to external water phase: 1:4; gas flow rate: 100 mL/min; stirring speed: 630 r/min; volume ratio of oil phase to internal phase: 1:1. The efficiency of tar removal was about 98 % at optimal operating conditions.
