Packing section for a gas/liquid separation column

A packing section configured to be installed in a casing so as to form a gas/liquid separation column, the packing section comprising:

• a treatment block configured to treat a fluid that has a generally cylindrical shape extending along a longitudinal direction;
• the treatment block being formed by a stack of treatment plates configured to treat the fluid along the longitudinal direction;
• the treatment block having a first disc-shaped face and a second disc-shaped face that each extend in planes parallel to one another;
• the treatment block having an external face extending over the perimeter of said treatment block between the first disc-shaped face and the second disc-shaped face;
• at least one holding element configured to hold the treatment block that extends at least partially around the external face of the treatment block;
• the at least one holding element having a holding portion for holding the treatment plates of the treatment block in position and a stop wall disposed at a longitudinal end of the at least one holding element and in contact with the first disc-shaped face, wherein the holding portion comprises an annular wall and an overlap wall;
• and
• a fluid return piece extends over the periphery of the packing section, the fluid return piece having a linking portion, which is substantially cylindrical and configured to be linked to the treatment block and to the at least one holding element, and a guiding portion configured to guide the fluid that extends the linking portion by forming an inclined plane of which the distance from the external face of the treatment block increases with increasing distance from the linking portion, the fluid return piece being separate from the at least one holding element, the linking portion being interposed between the at least one holding element and the treatment block.
