Stack loss data =============== Description ----------- The stack loss plant data of Brownlee (1965) contains 21 days of measurements from a plant's oxidation of ammonia to nitric acid. The nitric oxide pollutants are captured in an absorption tower. Notes ----- :: 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.
