PURPOSE : A device for recovering vapor gas of tanks is provided to reduce loss of raw and subsidiary materials due to a leakage of gas by mounting scrubbers for recovering vaporized raw materials, and prevent environmental pollution and fire risk due to a leakage of volatile gas. CONSTITUTION : Storage tanks(110, 111) store para-xylene and industrial acetic acid. Scrubber units(120) are formed at predetermined parts of the storage tanks for condensing evaporated para-xylene gas and industrial acetic acid gas. Absorbing towers(130, 140) contain para-xylene agglomerate and industrial acetic acid agglomerate. A solvent supply unit supplies a solvent to the para-xylene agglomerate and the industrial acetic acid agglomerate for dissolving the para-xylene agglomerate and the industrial acetic acid agglomerate. A re-treating unit(150) treats the solution dissolved at the absorbing towers again. © KIPO 2007
