This one has a lot of factors to take into account and there isn't a simple one line answer. Separators are designed to meet certain specs e.g. BS&W and vapour pressure of the oil product, oil content of the water product and liquids content of the gas.
For BS&W, higher temperatures do assist...

Don't forget that there will be several different settle out pressure depending on how the compressor was operating just before it shut down.
Normal settle out pressure will be much lower than if the compressor discharge was blocked and the relief valve lifting. If the discharge was blocked...
