I would like to ask: On the DCS display, the pressure in the upper tower is usually set at 30 kPa or 40 kPa. Is this pressure gauge pressure or absolute pressure?

The process conditions specified in the instructions are all annotated, usually indicated in gauge pressure.

It is generally expressed in gauge pressure; absolute pressure is used when specific standards apply~~ For example: 0.2 Mpa (gauge)~~
