Reason for the rapid increase in thermally stable salts in nitrogen-methyldiethanolamine
Thread Content
The amine solution in the unit was purified in April; the level of heat-stable salts after purification was below 2%. However, after three to four months of operation, the level of heat-stable salts has now risen above 6%. Why is the level of heat-stable salts increasing so quickly? What caused it? I ask fellow sailors to help clarify this.
Check the oxygen content; has the sulfite been oxidized to sulfate?
The increased content of thermally stable salts is probably brought in from the injections in the upstream unit. It is recommended that heat-stable salt purification facilities be kept operating continuously to reduce the level of heat-stable salts. Additionally, analyze the components of the thermally stable salts to prevent corrosion and leaks that could damage the equipment.
