The working principle of scale inhibitors, namely the formation of complex compounds (chelat) between scale inhibitor with the elements forming the crust. The complex compounds that form soluble in water so as to cover the possibility of a large crystal growth. Besides it can prevent the crust to crystals
attached to the pipe surface. In general the scale inhibitors
used in oil fields was divided into two types namely scale inhibitor of inorganic and organic inhibitors scale. SEthe life of inorganic phosphates are commonly used as an inhibitor is kondesat phosphate and dehidrat phosphate. Inorganic
phosphates are widely used as scale inhibitor before growing fosfonat, phosphate esters and polymers. Basically these chemicals contain group P-O-P and appropriate for clings to the surface of the Crystal. Bond oksigenfosfor
This is a very unstable in dilute solution and will terhidrolisa (reacts with water)
ortofosfat that does not produce aktif or does not function as a scale inhibitor. This reaction is commonly referred to as reversi
Scale inhibitor commonly used organic: organo fosfonat, organo phosphate ester and organic polymer-polymer. Organo phosphate ester effective for crust CaSO4, organofosfonat effective for crust CaCO3 and organic polymer-polymer effective
for a crust of CaCO3, CaSO4 and BaSO4.
Factors to consider in the selection of inhibitors are: effectiveness, stability, kacocokan
