My unit uses the FDFCC—Ⅲ process, and the lifting medium for the gasoline lift column is low-pressure steam; can it be replaced with dry gas?
Changing it to dry gas will reduce the gasoline yield
To change it to dry gas, it is necessary to verify whether the compressor load of the unit, as well as the loads of the absorption tower and the reabsorption tower, can meet the requirements.
It can be changed to dry gas; generally, the compressor load in FDFCC units is designed to be on the high side.
It is necessary to calculate the load on the compressor as well as the load at the rear.
It depends on the operational flexibility of your device! It should be possible to make changes, but the product distribution has to be taken into account!
It can be changed to dry gas, but it also depends on whether there is enough headroom in the compressor’s capacity.
Which factory do you work for? I’d like to exchange experiences regarding the production of FDFCC-3.

Keep going; change everything to dry gas, and also take into account the dry gas balance within the plant
