Low-temperature ethylene, liquid ammonia, propane vaporizer

What is the difference between using methanol and ethanol as heat exchange media in low-temperature regenerative vaporizers, when steam is used for heating in both cases? Are there any other media that can be used for thermal coal?
Consider properties such as the flash point, viscosity, heat transfer coefficient, toxicity, vapor pressure of the medium, as well as price options. Methanol and ethanol have good fluidity at low temperatures; water, on the other hand, tends to freeze. In terms of properties, kerosene and n-pentane can also be used. It depends on the specific use case, taking overall economic factors into account
