Data sets useful for process monitoring
| Website traffic | The number of visits to a small website on each day; if a user accesses the site after 30 minutes of inactivity, that will be logged as a new visit. | 214 | 4 | 12090 | |
| Kappa number | The Kappa number from a pulp mill. | 4462 | 1 | 3673 | |
| LDPE | Data from a low-density polyethylene production process. There are 14 process variables and 5 quality variables (last 5 columns). | 54 | 19 | 5521 | |
| Aeration rate | The total airflow added to an aeration tank, in litres, during a 1 minute period. | 573 | 1 | 4388 | |
| Paper basis weight | The dry basis weight of paper is a measure of its density. These measurements are from an online scanning gauge, taken 30 seconds apart at a large paper manufacturer. | 231 | 1 | 3421 | |
| Certificates of analysis | Four properties of an important powder raw material were transcribed from the supplier's certificates of analysis. | 122 | 5 | 3442 | |
| Rubber colour | The colour of a rubber product; this example is to demonstrate how to build a monitoring chart. | 100 | 1 | 3792 | |
| Industrial Batch Polymerization | 55 batches, each aligned to 100 equal time intervals (K = 100) for J=10 process variables measured throughout each batch. The batches are stacked vertically (rows 1-100 = batch 1, rows 101-200 = batch 2, etc). Values are scaled/normalized (dimensionless, … | 999 | |||
| Industrial Batch Dryer | A single workbook holding all four blocks, one per sheet: Z_operations: Operating-condition initial values; Z_chemistry: Chemistry initial conditions; X_batch: Aligned in-batch trajectory data; Y_quality: Final quality attributes (CQAs); The 59 batches in X_batch are stacked vertically with 325 samples each … | 1004 | |||
| Vapor pressure | Hourly process measurements from a distillation column that stabilises a hydrocarbon product stream in a refinery. | 18743 | 30 | 338 | |
| Styrene-butadiene rubber (SBR) batch reactor | Simulated emulsion polymerization of styrene-butadiene rubber: 53 batches, nine measured trajectories over 200 samples each, and five final latex quality attributes per batch. Two batches carry a known, deliberately simulated fault. | 1 | 1 | 849 |
