Gas absorption is a unit operation and separation process wherein soluble components of a gas mixture are dissolved in liquid solvent. This unit operation utilizes packing materials which play a vital role in providing surface area for gas and liquid contact. In this study, perlite from Lamba, Albay, Bicol was used in the production of packing material. The objectives of the study are to develop and characterize a packing material using a geopolymer derived from perlite and to design a packed column for the absorption of ammonia gas. The study determines the ideal perlite-Na 2 SiO 3  concentration, packing factor, and L/D ratio. Three perlite-Na 2 SiO 3  concentrations (45%, 60%, 75% wt. Na 2 SiO 3 ) were subjected to various tests such as: thermal stability, chemical resistance, and compressive strength. The 45% wt. Na 2 SiO 3  exhibited the least weight loss and the highest compressive strength making this geopolymerized perlite a potential packing material for gas absorption with a packing factor of 0.00175 ft -1 . Based on the results, a packed column was designed for the absorption of ammonia gas with an L/D ratio of 2.5.
