    With heavy crude oil towards the direction of development, but also more in-depth research work in close cooperation research institutions, oil and chemical manufacturers, research and development of our country has been completely meet the needs of demulsifier crude oil dehydration, the main types are summarized below.
    1、Alkyl phenol resin or a phenol resin, polyoxyethylene polyoxypropylene ether
  Commonly used in the synthesis of the initiator as nonylphenol or alkylphenol containing nine carbon-based mixed alkylphenols. If AF-3111, AF-831, AF-6231, AF-2036, etc., these products can be made according to the actual requirements of oil type, water-soluble type can also be made at the same time breaking both viscosity, paraffin effect.

  2、Ultra-high molecular weight demulsifiers
    Using triethylaluminum - acetyl acetone - water ternary catalytic system, alkylene polymers obtained by anionic polymerization with a molecular weight of up to 5 × 105 ~ 5 × 106, breaking excellent results. If UH-6535.
    3、Phenol-formaldehyde resin amine polyoxyethylene polyoxypropylene ether
   The condensation products of alkyl phenols with ethylene amines and formaldehyde as the initiator. Such as TA-1031, ST-12, ST-13 and the like. Such products suitable for low temperature dehydration, breaking effect, wide adaptability, with viscosity, paraffin role is more significant type of oil to use.
    4、Complex Demulsifier
   Knowledge through the introduction of solid paraffin inhibitor using a combination of two or more demulsifiers, exploit synergies between the paraffin inhibitor demulsifier demulsifier can improve performance and reduce the amount of demulsifier accelerate dehydration speed, save energy, but also to economic efficiency has been greatly improved. Currently used in the field such demulsifier has been very common.
    5、Polyoxyethylene polyoxypropylene phosphates
   Polyoxyalkylene ether and trichloromethyl phosphoryl (POCl3), phosphorus pentoxide (P2O5) in the reaction product. As ZPC, ZPT, PA-320 and so on. Such products in oil, water two phase are well dispersed, the interface has a good wettability, breaking fast is a good mixed crude oil demulsifier.
    6、Zwitterionic polymers
    The ring-opening polymerization of epichlorohydrin chlorinated polyether, a low molecular weight amine and quaternary ammonium. If CW-01, this product not only has good breaking effect, but also has corrosion inhibition, can effectively inhibit H2S, CO2, HCl and NaCl on metal corrosion.

   Companies adhering to the "technology-based, hard work, unity and hard work, the pursuit of excellence" spirit of enterprise, focused on providing quality products to new and existing customers in the petrochemical industry, you are welcome to come to consult, buy.
