Strippers (H2S, NH3)
Overview
Strippers for H₂S (hydrogen sulfide) and NH₃ (ammonia) are typically used in industrial processes to remove these gases from liquid streams. These are types of distillation columns or gas-liquid separation units designed to “strip” or remove volatile components like H₂S or NH₃ from a liquid phase (such as water or an amine solution) by using a gas, typically steam or air.
Key Concepts:
- H₂S Stripper:
- Removes hydrogen sulfide from a process stream.
- Common in gas processing, water treatment, and refining industries.
- The stripped gas, which includes H₂S, is often routed to a sulfur recovery unit or other treatment processes.
- NH₃ Stripper:
- Strips ammonia from liquid streams, such as wastewater or effluents.
- Often used in chemical plants, refineries, or water treatment facilities to reduce ammonia concentrations before discharge or reuse.
FRP is preferred in water treatment systems as it resists rust and chemical corrosion, making it ideal for harsh environments.
Manufacturing Process:
- Filament Winding: Glass fibers are wound around a rotating mandrel and coated with resin to form the pipe.
- Hand Lay-up: Layers of glass fiber are manually applied and impregnated with resin.
