<p>PROBLEM TO BE SOLVED: To provide a gaseous hydrogen chloride absorption device in which the frequency of replacement of a member for feeding hydrogen chloride containing fluid to a gas absorber can be reduced in gaseous hydrogen chloride absorption devices. SOLUTION: An absorber 21 is provided with a fluid feeding nozzle 22 for feeding hydrogen chloride containing fluid B, and in the end part on the upstream side of the fluid feeding nozzle 22, an indirect cooler 23 for indirectly cooling the hydrogen chloride containing fluid B is arranged side by side, and also the fluid feeding nozzle 22 is provided with a guide passage in which a guide cylinder leading to inside the absorber 21 at least from the head part of the guiding cylinder 24 and intended for guiding the hydrogen chloride containing fluid B cooled by the indirect cooler 22 to inside the absorber 21 and a heat exchange inner cylinder which is a constituent member of the indirect cooler 23 are integrated into one body. The contacted part with the hydrogen chloride containing fluid B leading to the head part of the guide cylinder from the indirect cooler 23 is formed of tantalum.</p> |
