During the initial water-cooled commissioning of the unit, should a reboiler be installed in the distillation tower?

The reboiler of the hydrocracking distillation column is heated by low-pressure steam; can the column be circulated when water is used for heat transfer? Do everyone’s hydrogenation units use a reboiler during water-cooled operation? :handshake

I’m not quite sure what you mean

The hydrocracking distillation column is equipped with a low-pressure steam heating reboiler; when operating in water-cooled mode, no steam is required to circulate the column. The reboiler is not used during the water commissioning of the hydrogenation unit.

No need to inject anything; the purpose of water transportation is not to raise the temperature, but rather to wash away slag and rust from within the pipes, as well as to check for any leaks in the flanges connecting the pipes!

No, during water-steam combined operation, if a reboiler is used, it will cause an excessive load on the top of the tower and no liquid level at the bottom of the tower, which can lead to safety issues as well as damage to the equipment. Besides, water is not a mixture, so it cannot illustrate the basic principles of distillation. Hydraulic testing is mainly used to inspect mechanical equipment and test its operational performance.

It can be put into use; by controlling the temperature well, it is possible to test how temperature changes, which is an excellent training opportunity for operators.
