After burning the desorbed gas in our converter, the flame color in the furnace chamber turned blue; we suspect this is due to a large amount of PSA exhaust gas or a high hydrogen content
In such a situation, asking for data from other units is of little use as a reference. It is best to compare the current analysis data with the historical data of one’s own company. It is also advisable to understand the changes in process operations and raw materials. Such changes need to be assessed based on the analysis data of one’s own company.
It’s because the calorific value of the PSA exhaust gas is insufficient; generally, the hydrogen content in PSA gas ranges between 20% and 30%. Not all of it can be PSA exhaust gas as fuel, as its calorific value is insufficient. The hydrogen content can be around 22~25%
