Natural gas processing technology dehydration 3
The document discusses solid desiccant dehydration. Solid desiccants like alumina, silica gel, and molecular sieves are commonly used to remove water from gas streams. They work by adsorption of water onto the desiccant surface. Key components of solid desiccant dehydration systems include adsorption towers filled with desiccant, a heater to regenerate the desiccant, and controls to direct gas flow during the adsorption and regeneration cycles. Design considerations include gas velocity, bed size, desiccant capacity, and pressure drop calculations.
