The two towers are connected in series, with no pump in between; pressure regulation is required to achieve stability
In my opinion, there are several reasons for this. Firstly, whether the pressure gradients before and after are stable plays a role; the systems prior and subsequent to it also have an impact, as do factors such as the liquid level, temperature, and reflux ratio in the two towers. It is recommended to stabilize each of these parameters one by one; once all the parameters are stable, I believe the situation will be fairly good
In addition to what was mentioned above, the cooling temperature of the vaporized substances at the top of the tower is also a relatively important factor.
The question you asked is too simplistic! Could you explain it in more detail?
