Vacuum distillates or residual fraction of vacuum distillates are the main source of lubricating oils from the petroleum industry. Although they account for only 1% of the volume of petroleum fuel sales they are a high value unit. Besides lubrication they are used as heat transfer mediums, hydraulic fluids, corrosion protection, etc., both in industry and society. 

A properly formulated engine coolant concentrate is composed of several essential ingredients, including base fluid, corrosion inhibitors, foam suppressor, dye, and water. 

Resistance to fluid corrosion is by far the most important aspect This topic is discussed in detail in the mentioned references, where extensive corrosion tables are given. From this point of view process fluids can be classified as follows ... 

High temperature and high pressure processing of materials often involves the use of supercritical fluids. Corrosion studies are quite essential for evaluation of the equipment in supercritical fluid operations. Previous electrochemical measurements for alloys in supercritical fluids are rare (1-1). The reported measurements (3) show that passivation of iron alloys is different at supercritical conditions compared to ambient conditions. The study of the electrochemistry of iron alloys can lead to control of corrosion of equipment utilizing the alloys. Thermodynamic analysis provides the information about stable species, i.e. corrosion products under given temperatures and pressures.
