Draw temperature from the owner’s heat exchanger in the air separation unit
Thread Content
Why is it necessary to monitor the temperature drawn from the main heat exchanger during the cooling phase of air separation unit startup? What are the indicators again? Thank you all for your advice
There is a problem with this statement itself; it’s better to understand the principle behind the operation of the entire device, and then this will no longer be an issue. The intermediate pump is used to control the inlet temperature of the expander; during equipment startup, what is required is a larger amount of cold gas, rather than achieving maximum efficiency by increasing the maximum temperature difference. Therefore, as long as the expansion turbine outlet temperature permits it, a lower inlet temperature is more beneficial for cooling the equipment. It is necessary to use the expander outlet temperature as a reference point; using the intermediate extraction temperature as a reference point would be too inaccurate. For reference.
