Solids plugging problems are often encountered during liquid-gas containing operations using a packed tower contactor. The invention alleviates or avoids such problems by providing a novel packing support grid characterized by a large total open area and large individual openings. The grid comprises vertically spaced upper and lower sets of laterally spaced bars. The vertical and lateral spacings are selected with respect to the size of the packing elements so that the packing elements cannot drop through the grid but at the same time the total open area of the grid is very large.
