**Description**: Snapshot measurements on 27 variables from a distillation column; measured over 2.5 years.
|
| 5 |
+
**Data source**: From an industrial source; variable names have been coded. e.g. Temp1 is a temperature, but we cannot disclose where it is measured on the column.
|
| 6 |
+
Temperatures are in Fahrenheit
|
| 7 |
+
Pressures are measured in bars
|
| 8 |
+
FlowC1 in units of MSCFD
|
| 9 |
+
FlowC3 and FlowC4 are in units of MBPD
|
| 10 |
+
Temp11 = Temp3 - Temp9 = the temperature increase of the stream leaving the column and returning back, after passing through the reboiler
|
| 11 |
+
InvTemp tags are 1000/temperature, therefore with units of inverted Fahrenheit
|

+
The last column, VapourPressure, is a quality variable measured in the laboratory. The other snapshot measurements in the row correspond to the process conditions when the sample was taken.

**Data shape** 253 rows and 27 columns
