The nitric oxide pollutants are captured in an absorption tower.a³:: Number of Observations - 21 Number of Variables - 4 Variable name definitions:: STACKLOSS - 10 times the percentage of ammonia going into the plant that escapes from the absoroption column AIRFLOW - Rate of operation of the plant WATERTEMP - Cooling water temperature in the absorption tower ACIDCONC - Acid concentration of circulating acid minus 50 times 10. có—t¦«S)ú¤ Load the stack loss data and returns a Dataset class instance.
