| (3) Calculate the hourly average pressure drop across the scrubber for each hour of the performance test; and | |||
| (4) Calculate and record the minimum pressure drop as the average of the hourly average pressure drops across the scrubber for the two or three test runs, whichever applies. | |||
| b. Establish the operating limit for the minimum scrubber liquid pH | i. Data from the pH measurement device during the performance test | (1) At least every 15 minutes, measure scrubber liquid pH; and | |
| (2) Provide at least one pH measurement during at least three 15-minute periods per hour of testing; and | |||
| (3) Calculate the hourly average pH values for each hour of the performance test; and | |||
| (4) Calculate and record the minimum liquid pH as the average of the hourly average pH measurements for the two or three test runs, whichever applies. | |||
| c. Establish the operating limit for the minimum scrubber liquid flow rate | i. Data from the flow rate measurement device during the performance test | (1) At least every 15 minutes, measure the scrubber liquid flow rate; and (2) Provide at least one flow rate measurement during at least three 15-minute periods per hour of testing; and |
|
| (3) Calculate the hourly average liquid flow rate for each hour of the performance test; and | |||
| (4) Calculate and record the minimum liquid flow rate as the average of the hourly average liquid flow rates for the two or three test runs, whichever applies. | |||
| d. If chemicals are added to the scrubber liquid, establish the operating limit for the minimum scrubber chemical feed rate | i. Data from the chemical feed rate measurement device during the performance test | (1) At least every 15 minutes, measure the scrubber chemical feed rate; and (2) Provide at least one chemical feed rate measurement during at least three 15-minute periods per hour of testing; and |
|
| (3) Calculate the hourly average chemical feed rate for each hour of the performance test; and | |||
| (4) Calculate and record the minimum chemical feed rate as the average of the hourly average chemical feed rates for the two or three test runs, whichever applies. |
