Abstract Static Dissipater Additive (SDA) is conductivity improver additive that is added to low sulfur fuels to avoid sudden increase in conductivity that may occur during transfer/pumping of fuel. Due to surface active nature, SDA dosage may deplete with time. The monitoring of concentration of SDA is very critical and is carried out using conductivity measurement as per ASTM D2624. In this study, four ATFs and three HSD were doped with SDA (0.2–3 ppm) to see their response toward dosage of SDA with respect to conductivity improvement. The differences in the response of different ATFs/HSD have been explained using physico-chemical data.

航空涡轮燃料和HSD对静电耗散添加剂的电导率响应；差异及其原因

摘要 静电耗散添加剂（SDA）是一种导电性改进剂，添加到低硫燃料中，以避免在燃料传输/泵送过程中可能发生的导电性突然增加。由于表面活性的性质，SDA 剂量可能会随着时间的推移而耗尽。SDA 浓度的监测非常关键，根据 ASTM D2624 使用电导率测量进行。在这项研究中，四个 ATF 和三个 HSD 掺杂了 SDA（0.2-3 ppm），以观察它们对 SDA 剂量在电导率改善方面的反应。已使用物理化学数据解释了不同 ATF/HSD 响应的差异。
