It is a kind of organic aliphatic acid polymer. The molecular weight is around 400-800. It is soluble in water and quite stable. It will be decomposed when the temperature is higher than 330℃. It still shows excellent threshold effect in high temperature(<350℃) and high PH(8.3). it can be used by mixing with crude oil dehydrating demulsifier and it has good scale inhibition to carbonates and phosphates, which can last for 100h. it is low toxicity, no carcinogen and can be degradation by microorganism which is harmless to the environment.
It’s often mixed with organic phosphate by 2-5ppm.
(4) packing and storage:
Packed in 25kg plastic bucket. It can be stored for 2 years.
