Hot Oil Heaters

Hot oil heaters are process units that heat a fluid (typically a thermal oil) which is subsequently used to heat other processes within a refinery/processing plant. This ‘indirect heating’ is used when the fluid to be heated would be adversely affected by direct heat or when precise control of the heating temperature is needed. Examples of the former include regeneration of glycol (from dehydration units), regeneration of amine (from CO2 and sulphur removal processes) and oil stabilisation. Examples of the latter include heating for reboilers in the fractionation of NGL’s (Natural Gas Liquids) either as a standalone process or as part of the LNG process.
