Ammonia Separation and Decomposition Process

  • Ammonia Separation and Decomposition Process
  • Combustion and melting technology
  • Concentration, acid, distillation technology

The temperature of ammonia gas, separated from the stripper by air diffusion, is increased up to a specified temperature for oxidative decomposition with a catalytic reactor. Heat after oxidative decomposition is used for air diffusion, which reduces running cost.

Ammonia in wastewater is nitrified in the water environment by microorganisms and changes into nitrate-nitrogen or nitrite-nitrogen that adversely affects human beings.
In 2004, the 5th Water Quality Immutable Weight Control was enforced, which started control on nitrogen and phosphorus as substances for eutrophication. The control will be stricter year by year.
We have marketed high-performance packing for many years, and based on our expertise of packing, we have developed and marketed distillation separation equipment. Moreover, to decompose and treat separated ammonia, we provide separation recovery equipment and separation decomposition equipment, incorporating the catalyst technology of Nippon Shokubai.

Features

Reuses decomposition heat of ammonia

Major Applications

Removal and detoxification of ammonia in wastewater

Major Applications

Ammonia Stripping Technology

Ammonia in wastewater is present as ion where pH is neutral. Ammonia is separated as gas from wastewater by raising pH of water with alkaline addition. Separation is enhanced by increasing the operating temperature of the tower
 
Features
・Applies to wastewater containing ammonia in a wide range from low to high concentration.
・Provides either ammonia recovery process or ammonia decomposition process, determined by the amount of ammonia contained in steam at top of the stripper, or benefits of its recovery
・Decreases ammonia in wastewater to a level below the regulatory concentration level
・Applies energy-savings by using effluent water from the base of the stripper tower for heating up wastewater
