Understanding the Industrial Process
Ammonia Anhydrous Liquid in Flue Gas Denitration
Ammonia anhydrous liquid serves a critical purpose in flue gas denitration for iron and steel plants. It acts as a reducing agent in selective catalytic reduction (SCR), a widely used technique to control nitrogen oxides (NOx) emissions. During the SCR process, ammonia is injected into the flue gas stream, where it reacts with nitrogen oxides in the presence of a catalyst. This chemical reaction converts harmful NOx compounds into harmless nitrogen and water vapor, aligning emissions with strict compliant flue gas emission standards.
Efficient operation requires a steady and reliable supply of ammonia anhydrous liquid. Ammonia storage tank systems are integral for uninterrupted SCR processes. Insufficient ammonia flow or pressure fluctuations can lead to rapid exceedance of regulatory NOx limits and risk costly compliance violations. Maintaining consistent ammonia storage and delivery therefore underpins effective flue gas emission control and ongoing adherence to national and regional environmental standards.
Risks in Liquid Ammonia Storage
Liquid anhydrous ammonia storage tanks are typically constructed from high-grade carbon steel, engineered for high pressure and low temperature containment. Most tanks are vertical or horizontal cylindrical vessels, equipped with reinforced welds and thermal insulation to limit boiling and minimize vapor loss. Critical aspects of tank engineering address the need for zero leakage ammonia systems; flange connections, seal gaskets, and emergency pressure relief valves are designed and maintained to prevent accidental releases.
Safety is paramount due to the substantial ammonia liquid toxicity risks. Ammonia vapors pose severe hazards to respiratory and ocular tissues. Short-term exposure at concentrations above regulatory threshold limit values can cause respiratory distress or fatal poisoning. Because ammonia is also flammable and may form explosive mixtures with air at certain concentrations, tank areas must be equipped to mitigate ammonia handling flammable and explosive hazards—this includes continuous pressure measurement systems for ammonia storage and automatic feed cutoff technology for ammonia tanks.
Spill and leak prevention rely upon robust spill containment, double-walled construction, and regular on-site ammonia exposure monitoring. Plant safety managers must implement liquid ammonia spill prevention strategies such as perimeter diking, rapid-response neutralization materials, and remote diagnosis in ammonia storage management to detect and address containment breaches swiftly.
Storage and handling practices are strictly regulated. Occupational ammonia storage tank safety regulations require vapor detection, ventilation, emergency shutdown systems, and periodic inspection. Agencies enforce ammonia emission monitoring and compliance to safeguard both personnel and the surrounding environment. Exposure limits for ammonia gas are set by regulatory bodies to minimize health and safety risks during all aspects of storage, transfer, and usage.
