Guidelines for Charging Primary Reforming Catalyst via Wet Method
1 like831 views
GBH Enterprises specializes in refinery process catalysts, performance evaluation, and new technology development for refining and petrochemical industries. They provide guidelines for charging primary reforming catalysts via a wet method which involves partially filling the reformer tubes with water during catalyst charging, allowing for drainage, and slowly drying the catalyst over 10-12 hours at increasing temperatures below the dew point to avoid breakage. The guidelines are meant to supplement accepted plant procedures for safe catalyst charging and start-up.

Given this, they are indeed suitable for charging via a wet method. Following are some guidelines for how this should be accomplished. During Charging: - Fill the reformer tubes approximately 2/3 full of water to begin. As the catalyst is charged into the tube, water should slowly be drained so that it does not overflow and wet the furnace refractory. - After charging the tubes, allow the water to drain for an extended period of time. - Pressure drop measurements across the tubes should be within +-5% of the average for all tubes. - Putting the Catalyst in Service: - If possible, pass air or gas over the catalyst for a while to remove excessive water. - Slowly dry the catalyst with a flowing system (typically nitrogen), and maintain the temperature at 80-90C for a period of 10 to 12 hours. - Raise the temperature to 120C for four hours to complete the drying phase. It is intended that temperatures listed here and above be lower than the dewpoint to avoid breakage of the catalyst. - The temperature in the tubes should not exceed 100C in the first drying steps. Therefore, the carrier gas should be heated by an external source, instead of using the burner flames. - After completing the drying steps, proceed with normal furnace start-up procedures. These guidelines are meant to be used as aids to accepted and documented plant procedures.
