Here are my thoughts:
The switch from MPS to superheated LPS (whatever pressure levels those acronyms mean) has been frequently done for economic reasons.
The superheat of the LPS is needed for two main reasons:
A cooler steam reduces the stripping efficiency by slightly cooling the naphtha, which, to compensate, would require an increase in flow rate, more friction drop and more load to the top condensers. Therefore superheating the LPS would enable to keep the same steam mass flow rate.
Another reason is that although throttling saturated steam through control valves produces some superheat, do not use saturated steam for stripping, because it may contain (and usually does) water that could evaporate violently damaging the stripper internals.
