Chlorine injection rate and chlorine loss in continuous reforming units
Thread Content
The processes used in domestic continuous reforming units are mainly the UOP process and domestic ultra-low pressure processes. May I ask industry experts: what is the typical chlorine dosage used in continuous reforming units these days? What is the typical loss of chlorine injection amount in the charring zone?
The chlorine injection amount for regeneration is determined based on the chlorine content of the catalyst to be regenerated; as for how much can be lost in the coking section, that is unknown. There is also no way to take samples.
The amount of chlorine to be added is calculated based on the chlorine content of the regenerant; it is best to keep the chlorine content in UOP’s regenerants at 1.1%. R334
The burning loss is around 0.2%.
The amount of chlorine to be added is determined based on the chlorine content of the catalyst to be activated; manufacturers provide the corresponding calculation formulas in their general operation manuals. As for the loss of burnt chlorine, it is generally 0.2% in the case of IFP.
The chlorine injection control is generally set at 1.1%, or it can also be determined as (regenerator + raw material)/2; a value greater than 1 is sufficient. Normally, the HCl content in the cycle hydrogen is around 5 ppm. Or detect C3/C1 in the recycled hydrogen
