Scale Inhibitors
Scale occurs because the minerals in produced water exceed their saturation limit as temperatures and pressures change.
scale can vary in appearance from hard crystalline material to soft, friable material and the deposits can contin other minerals and impurities such as paraffin, salt and iron, scale inhibitors are used to pervent these deposits from forming .
It has been developed to prevent scale in curde oil production operation. Such as phosphate esters,Phosphonates and Phosphonic Acids.
