Within the manufacture of high temperature geothermal fluid, the dimensions inhibition result of some of the previously mentioned scale inhibitors will be drastically reduced. Antiscalants like polyphosphates and phosphate esters are frequently only used at temperatures beneath 66 °C because of their small thermal stability. Phosphonate scale inhibitors have exceptional scale inhibition performance, nevertheless, these merchandise typically come to be unstable at temperatures about 149 °C. At this time, small molecular body weight polycarboxylates as well as their derivatives are greatly used for high temperature calcium scale control due to their thermal threshold up to 260 °C.[78] To select an suitable scale inhibitor for deepwater high temperature applications, Wang et al.[78] evaluated the thermal stability and scale inhibition overall performance of five polymeric scale inhibitors.
