Manufacturing Process

Great quality of urea solution is required in order to maintain long-term high-price SCR system.
Super Pure Water

Small amounts of heavy metals in the water combine with nitrogen oxide and results in metallic salts, and so Super Pure Water must be used.

LOTTE Fine Chemical operates manufacturing facilities for super pure water and applies to urea solution in order to produce detergents for semiconductors.

Good quality urea

Urea is produced by coal, naphtha, and natural gas, and is combined with abundant amounts of water during the process, and often contamination results during the storage and transportation process.
In this process, LOTTE Fine Chemical extracts and uses pure urea in the middle process through a separate method for producing urea for urea solution.

Quality Assessment

The quality of the urea solution produced cannot be guaranteed unless an independent analyzing system that can accurately assess the quality of super pure urea is in hand.
Also, a method for collecting urea solution that does not meet the regulation standard must be acquired.
This is because it takes significant amounts of expenses in order to burn and discard mis-produced urea solution.
LOTTE Fine Chemical re-collects the mis-produced urea solution that does not meet the quality requirements back to the urea solution factory.

Urea Solution Refinement

Through LOTTE Fine Chemical’ advanced refinery system, best-quality urea solution is produced.

Quality Importance

Reason for selecting good quality urea solution

The SCR(Selective Catalytic Reduction) technology for vehicles restores nitrogen oxide into nitrogen and water vapor in order to pass the urea solution and emission gas from engines through the catalyst, and it is the most stable system developed up to date and has a high fuel-efficiency compared to other systems due to its lessening loads on the engine.
Good quality urea solution
Bad quality urea solution

Compressed Air
O2N2

Compressed Air
O2N2

Nitrogen oxide from emission gas of engines area decomposed to nitrogen and water vapor through the process of good quality urea solution and compressed air combining to emission gas of engines.
The catalyst layer gradually contaminated by the heavy metals contained in the bad quality urea solution combines with compressed air and emission gas of engines. The contaminated catalyst layer will be produced in air, not able to decompose the nitrogen oxide.
다음 설명
The International Standard Organization (ISO) and the Ministry of Environment applies the minimum standard in order to protect the catalyst.
To conclude, a good quality urea solution is an urea solution that has the lowest amount of heavy metal components.
The lowest amount it has, the longer it can be used and vehicles and the environment will be protected.
