AI Overview
Sulfonation plant air drying systems remove moisture from ambient air to prevent
from forming acid mist, typically achieving dew points of -60°C to -80°C. The process involves compressing air with a Roots blower, cooling it to ~5–7°C (45°F) using water/glycol chillers, and passing it through desiccant-adsorbers (usually silica gel or molecular sieve).
