    Best Marine urea solution AUS40 for ships terminal | Saqrme ...
    Marine urea liquid, often referred to as AUS 40 (Aqueous Urea Solution 40%), is a high-purity, 40% urea solution used in marine Selective Catalytic Reduction (SCR) systems to reduce NOx emissions from large ship engines. It converts nitrogen oxides into harmless nitrogen and water vapor, ensuring compliance with strict environmental regulations. 
    Key Aspects of Marine Urea Liquid: 
    • Composition & Quality: Contains 39.5%–40.5% urea, typically meeting ISO 18611 standards to prevent SCR catalyst contamination.
    • Application: Injected into the exhaust gas stream of marine vessels, including container ships, tankers, and ferries.
    • Storage & Stability: Remains stable for up to 18 months at temperatures between
      0∘C0 raised to the composed with power C
      0∘C
       and
      25∘C25 raised to the composed with power C
      25∘C
      . Temperatures above
      35∘C35 raised to the composed with power C
      35∘C
       can cause decomposition into ammonia and carbon dioxide.
    • Advantages: Offers logistical advantages over solid urea (granules) by eliminating onboard mixing, and provides better performance in high-torque marine engines compared to weaker solutions.
    • Comparison: Unlike 32.5% DEF used in road vehicles, marine systems usually require a 40% concentration (AUS 40). 
    Commonly available in bulk, intermediate bulk containers (IBCs), or produced on-board via specialized generators, marine urea is vital for modern maritime environmental compliance.
