What Problems Should We Pay Attention to in Marine Urea Solution?

2022-09-08 11:29:54


Marine urea solution - diesel engine tail gas treatment solution, also known as nitrogen oxide reducing agent (commonly known as: Aqueous urea solution 40%), called AUS 40



How much AUS 40 should be added to the ship at one time is also a question that everyone is concerned about. Because the size of the ship is different, the solution storage tanks that come with the ship are also different. Like some voyage ships,they will even consider some consumption of the return, so the ship will also bring some of its own, because the consumption of ships is generally relatively large.What’s more, the packaging requirements used are mainly ton barrels, which is convenient for filling and easy to store.


According to the existing exhaust emission standards, ships must now add AUS 40,or the emission does not meet the standard. Marine AdBlue AUS 40 technical parameters:


Urea content (Urea Content)% (m/m)
 39.5 – 40.5
Density / 20 ℃ (Density at 20°0C) g/cm
31.093 – 1.107
Refractive Index (Refractive Index at 20°0C) 
1.395 – 1.398
Alkalinity (Alkalinity as NH3)% (m/m)
< 0.2
Biuret (Biuret) % (m/m)
< 0.3
Aldehydes (Aldehydes) mg/kg
< 5.0
Insoluble Matter (Insoluble Matter) mg/kg
< 20.0
Phosphate (PO4) mg/kg
< 0.5
Sodium (Sodium) mg /kg
< 0.5
Aluminum (Aluminum) mg/kg
< 0.5
Calcium (Calcium) mg/kg < 0.5
Chromium (Chromium) mg/kg
< 0.2
Copper (Copper) mg/kg
< 0.2
Iron (Iron) mg /kg 
< 0.5
Magnesium (Magnesium) mg/kg 
< 0.5
Nickel (Nickel) mg/kg 
< 0.2
Zinc (Zinc) mg/kg 
< 0.2
Potassium (Potassium) mg/kg 
< 0.5

(the general concentration standard is in About 40%, we should also pay attention to a problem. Some small ships can also be added according to the standard of urea for vehicles. During this process, it is necessary to understand the standard value of a concentration with the customer)



With the increasing popularity of AUS 40, there will also be a standardized process for its production standards, because the exhaust gas emitted by ships is also very large, and environmental energy saving has always been an inevitable problem in development. Therefore, with the advancement of technology , The perfection of the formulation of standards can better protect the environment. In the process of producing AUS 40, we have always produced standard standards, so as to truly protect the environment.
