How is hydrogen in coke calculated? I would like to use this to determine whether the amount of stripping steam used is appropriate; I seek the expert’s advice.
Adjust the amount of stripping steam; whether the amount is appropriate can be determined by observing the changes in regeneration temperature
Under normal conditions, the maximum amount of stripping steam is used first, after which the amount of stripping steam is gradually reduced until the regeneration temperature starts to change; then it is increased by 200–300 kg/h, thereby determining the optimal amount of stripping steam. The specific calculations also need to be adjusted to the appropriate amount using such a method. As for the H content in coke, it can be calculated using the heat balance of coking in the regenerator; relevant information is available for reference!
The hydrogen content in coke can be calculated based on the flue gas composition, with oxygen balance and nitrogen balance being primarily used for this purpose
