Summary:There is provided a method for extracting a gaseous fluid which comprises extracting the gaseous fluid through fluid extraction ports set up on the top face portion of a vertical-type agitation tank equipped inside with an agitator, wherein two fluid extraction ports are set up at positions approximately symmetrical about the center of the top face portion of the vertical-type agitation tank, or wherein at least three fluid extraction ports are set up each at a vertex of an approximately regular polygon having the central point identical with the center of the top face portion of the vertical-type agitation tank. It is made possible by the foregoing method to suppress the entrainment of fine particles and mist, curtail clogging of a filter and the like, contrive uniformization for the temperature of the content and at the same time, ensure a stable operation by extracting a gaseous fluid through a plurality of extraction ports each set up at a specific position on the top face of a vertical-type agitation tank.
