If the words used were "restart" - then I would think they might want to resume some operations (at one time they did consider restarting the Naphtha Unit - the first stage in refinery operations).
With all due respect, the first stage of any petrochemical refinery begins in the Crude Unit, being the crude distillation tower the exact starting point for crude refining, from then on it goes to other units. For example, the bottoms section of the crude unit tower provides the feedstock for the vacuum unit, which is where you get your solvents, etc.
The naphta unit, whether called a hydrotreater or a pre treater, is only a filtering unit and no refining takes place there, and that applies to all hydrotreater units (KHT, DHT, GHT, etc.). They may, however, perform splitting and stripping in those units to remove good products, like hydrogen, heavy hydrocarbons, not so good, like sulfur, H2S, etc.
Those that are bored may want to watch the documentary "Modern Marvels: Secrets of Oil" to learn the very basics. On said program, you will learn that one of the active ingredients in aspirin is found in the stream coming off the top of the crude tower.
I apologize for the thread hijacking. I'll now let the refining and stream of rumors continue...
This isn't exactly correct. A naptha unit would typically refer to a unifiner or a reformer unit. The unifiner sweetens the naptha as either blending stock or reformer feed, and the reformer improves the octane of the naptha. They catalytically treat the naptha, and do not simply filter or split or strip them, though the reactor effluent does go through some degree of this processing. Any processing of the raw naptha like that could be accomplished at the upstream crude unit. Hydrotreater is typically the term used for distillate treating units(diesel, jet fuel, heating oil).
