Process Overview
The Ammonia Plant utilizes Natural Gas as a feedstock, which undergoes a series of chemical transformations:
Steam Reforming
Natural gas (hydrocarbons) reacts with steam to produce hydrogen (H₂), carbon monoxide (CO), and carbon dioxide (CO₂).
Air Injection
Air is introduced to provide a source of nitrogen (N₂) for ammonia synthesis.
CO Shift Conversion
Carbon monoxide is reacted with steam to form additional CO₂ and H₂.
CO₂ Removal
CO₂ is absorbed and removed using a potassium carbonate (GV) solution.
Methanation
Residual CO and CO₂ are converted into methane.
Ammonia Synthesis
Hydrogen and nitrogen react under high pressure and temperature to form ammonia (NH₃).
Ammonia Separation & Purge Gas Recovery
The product ammonia is separated, and unreacted gases are partially recovered for reuse.
Environmental Sustainability: Zero Liquid Discharge
KFL’s Ammonia Plant is designed with built-in environmental protection systems to minimize waste and support zero-effluent operations:
- Process Condensate Stripper: Removes dissolved gases; the treated water is sent to the DM plant for reuse.
- Turbine Condensate Recovery: Polished and reused as boiler feed water.
- Boiler Blowdown Reuse: Redirected as cooling tower make-up water.
These features reflect KFL’s commitment to resource conservation, water reuse, and sustainable manufacturing.
