Breaking through the theoretical framework and bottleneck that traditional high-temperature corrosion inhibitors can only use phosphorus-based systems, it provides good corrosion inhibition under vacuum conditions at 220~360℃, and avoids fouling, blockage and unplanned shutdowns of downstream units such as hydrotreating caused by phosphorus-containing high-temperature inhibitors.

| Appearance | brown viscous liquid | Light yellow clear liquid |
| Solubility | Soluble in aromatics/diesel oil | Water soluble/oil soluble optional |
| Usage | Need to be diluted in proportion and then injected | Direct pump injection (ready to use) |
| Applicable customers | Formulators, high-volume users | Directly used by terminal refineries |
| unit price | Higher (concentrated) | Lower (equivalent based on effective content) |
The comprehensive costs of the two are equivalent after conversion based on effective content. Formulators usually purchase raw solutions and prepare them themselves; it is more convenient for terminal refineries to directly purchase preparations.
BXH-103 stock solution has high viscosity and cannot be pumped directly. It needs to be diluted as follows before use:
