Recommended temperature for Heater Treater

[aegis4048]

Is there any standards or charts that can help decide good operating temperature of a heater treater? A bit of studies I've done tells me that recommended heater T depends on the following:

1) API gravity of oil
2) viscosity of oil
3) operating pressure of heater
4) Field experience of your region
5) (any others?)

If I ask you, "What is a recommended T for heater", your answer is probably "It depends". Please give me some scenario-specific examples. It would be the best if there's any published charts or correlations that can help me decide operating T of heater, given the above dependencies. I tried to find such ones, but couldn't find any.

Thanks,

Stubborn emulsions are stabilised by either one or both of the following also:
suspended solids carrying electrostatic charge
corrosion inhibitors, where one mode of inhibition is by deliberate chemical emulsification of the water and crude phases ( similar action to surfactants used in laundry powder).

If you cook and have ever made Hollandaise, or mayonnaise, or alfredo sauces you know how tricky this can be.
Slight shifts in temperature, pH, water content, minerals in the water, other additives, and variation in the oil can all raise havoc with emulsion stability.
This is why you have to work it out for yourself.
There is no cookbook for this.
