The invention relates to a removing method of organic sulfur in coke oven gas. The method mainly solves the technical problems that organic sulfur compounds in the coke oven gas purification cannot becompletely removed in the prior art, and discharge of sulfur dioxide in tail gas after combustion exceeds standards. The removing method of organic sulfur in coke oven gas comprises the following steps: a. coke oven gas from a coke oven enters a rough debenzolization unit, and after rough desulphurization, a stream I is formed; b. the stream I enters a rough desulphurization unit, and after roughdebenzolization, a stream II is formed; c. the stream II enters an integrated purification tower, the integrated purification tower contains an adsorbent of molecular sieve kinds, and aromatic hydrocarbons and organic sulfur compounds in the gas are removed at the same time in order to form a stream III; c. after the stream III enters a compressor for compression, the stream is sent to a gas turbine for power generation, and tail gas after combustion in the gas turbine is emptied. The technical scheme better solves the problems, and can be applied to industrial production of power generationof coke oven gas.
