esulfurization 
defoamer is
 specifically
 research
 for
 
gas desulfurizer - MDEA)
which has 
good compatibility with foaming medium
. The product has excellent 
defoaming and
 f
oam suppression
 performance for the
 foam produced by the addition of desulfurizer in the packed tower
 i
n the process of  gas desulfurization
. P
articularly useful when foam suddenly builds up in the absorber and rapid control is needed
. 
Suitable for long - term use of water - based system such as desulfurization slurry.

4. Method of use
It 
can be used directly or diluting before adding
,its recommended dosage is 0.01~0.3%.
The specific
 dosage
 and actual amount of addition depends on the actual situation on the site.
5. Precautions:
In case freeze took place during transportation and storage, the defoamer should be unfreeze naturally, and stir evenly before use.
6. Package and Storage
Use 200kgs, 1000kgs packages, or negotiated packages. Sealed and stock under room temperature, away from light. Avoid the defoamer exposed to extremely cold or hot environment. Shelf life is 1 year.
7. Security
Avoid contact with eyes and respiratory system. Once happen, please wash with lots of clear water, to see a doctor is necessary if the situation is serious.
