Ammonia Synthesis Tower & Column

The Ammonia Synthesis Tower is a core reactor system in modern fertilizer plants, designed to convert nitrogen (N₂) and hydrogen (H₂) into ammonia (NH₃) under high pressure and temperature in the presence of a catalyst. This tower ensures efficient conversion rates, stable operation, and long catalyst life, while providing the reliability required for continuous industrial production. As a critical unit in the ammonia production process, it plays an essential role in meeting global fertilizer demand and supporting sustainable agricultural output.

WSHI designs and fabricates a full range of process towers and columns for catalytic reactions, absorption, separation, distillation, and stripping services. Engineered to withstand extreme pressure, temperature, and corrosive media, our towers are widely applied in petrochemical, refining, fertilizer, and energy industries. With proven expertise in metallurgy, pressure vessel design, and advanced fabrication, WSHI delivers reliable and efficient solutions tailored to demanding industrial applications.
