Defoamer for oil field is a kind of silicone polyether graft copolymerization defoamer, it can well solve the foams which forming in well drilling, avoiding causing side effect to the production.

It can keep strong defoaming and foams suppressing ability in the conditions of high temperature, strong acid, strong alkali, or high shear, thus, this defoamer is widely used in various kinds of severe foaming systems to control foams in a wide temperature range.

Furthermore, this defoamer still can solve the foams which produced by delay coking.

Features: Low silicone content, small volatility, high temperature stability.   

(1) Fast defoamer ability, lasting foam suppressing effect.

(2) Good dispersibility, easy and simple usage.

(3) Small dosage, high efficiency, improve the lubricating property and cooling effect of slurry, largely improve the efficiency of slurry recycling using.

(4) Non-toxic, odorless, no pollution to environment. 

Defoamer for oil field is used in oilfield drilling mud, mortar, mining, beneficiation, and oil water separation process, etc.

                                  Apply to oil water separation      　　　 　　    　                                     Apply to oilfield drilling mud 

1. Direct add this defoamer to the well drilling mud as additives, when formulating mud, firstly add the defoamer to soil particle, stone particle. 

2. Also can add this defoamer to the slurry mixing trucks box.

3. Recommended dosage: 0.02%~0.03%

Delay coking process:

1. The foam forming in the coking tower, as the material viscosity largening and the solid forming, it would form a stable foam layer, using this defoamer can reduce the height of foam layer, and prevent the overflowing situation. This defoamer normally it’s added from the top of coking tower, and often use light gas-oil inject in, the main application of carrying oil is to keep the cleaning of pipeline and help the silicone oil to distribute to the foams.

2. Recommended dosage: 3ppm~10ppm, before using, please dilute this defoamer with coal oil or diesel oil to 1~10 times.

3. The specific usage shall be determined through the laboratory test.

 1. Packing: 60KG, 200KG, 1000KG /Plastic drum, or as customer required.

2. Storage: Non-dangerous goods, non-toxic, non-flammable. Should be stored sealed, in a cool, ventilated and dry place. Before used up, the container should be sealed tightly at around 25℃.

3. The shelf life is about 12 months.

4. Transportation: This product should be sealed well during transportation, preventing from moisture, water, strong acid & strong alkali.
