How to calibrate the oxygen flow rate after temperature and pressure compensation?
Generally, it can be found using a table based on oxygen pressure and temperature; as for calibration, it is done using a gas tank

The key is to ensure that the total amount of oxygen from the air separation unit and that from the gasification process is consistent, and also to verify that the flow rates displayed on both the DCS and SIS systems are the same. There will definitely be variations in the flow rates of air separation and gasification.
There is always a certain flow deviation between air separation and gasification; in my case, the difference is over 1,000.
