As stated in § 63.1567(a)(2) , you shall meet each operating limit in the following table that applies to you.
For each applicable process vent for a new or existing catalytic reforming unit with this type of control device . . . | You shall meet this operating limit during coke burn-off and catalyst rejuvenation . . . |
1. Wet scrubber | The daily average pH or alkalinity of the water (or scrubbing liquid) exiting the scrubber must not fall below the limit established during the performance test; and the daily average liquid-to-gas ratio must not fall below the limit established during the performance test. |
2. Internal scrubbing system or no control device (e.g., hot regen system) meeting outlet HCl concentration limit. | The daily average HCl concentration in the catalyst regenerator exhaust gas must not exceed the limit established during the performance test. |
3. Internal scrubbing system meeting HCl percent reduction standard. | The daily average pH or alkalinity of the water (or scrubbing liquid) exiting the internal scrubbing system must not fall below the limit established during the performance test; and the daily average liquid-to-gas ratio must not fall below the limit established during the performance test. |
4. Fixed-bed gas-solid adsorption system | The daily average temperature of the gas entering or exiting the adsorption system must not exceed the limit established during the performance test; and the HCl concentration in the adsorption system exhaust gas must not exceed the limit established during the performance test. |
5. Moving-bed gas-solid adsorption system (e.g., ChlorsorbTM System). | The daily average temperature of the gas entering or exiting the adsorption system must not exceed the limit established during the performance test; and the weekly average chloride level on the sorbent entering the adsorption system must not exceed the design or manufacturer's recommended limit (1.35 weight percent for the ChlorsorbTM System); and the weekly average chloride level on the sorbent leaving the adsorption system must not exceed the design or manufacturer's recommended limit (1.8 weight percent for the ChlorsorbTM System). |
