Acid gas drying is a process that removes a large percentage of the water vapor in natural gas, allowing for a more stable pipeline and decreasing corrosion, hydrate formation, and the need for corrosive chemicals.
Zeolites are crystalline, silica-based materials with a unique structure of interconnected tetrahedral units that creates a lattice of pores and channels throughout the crystal.lay zeolite This pore and channel structure is the basis for the adsorption, catalytic, and other properties of zeolites.
