Maybe you ought to go back and read LimeTree's original proposal where they said that they "might" want to restart the Naphtha Unit but it was unlikely they would run any other part of the refinery. Now maybe, they would run the "Crude" section, but that was not what they indicated.

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...

Specify Lake County, FL please. Not universally true for all of Florida.

Yep. Moved to FL where you can actually have affordable healthcare insurance, drive on clean, pothole and trash free, well lit roads, have access to an abundance and variety of very fresh fruits and vegetables at low prices, have mail and packages delivered to my door, inexpensive utilities, trash pick up and recycling, twice weekly which is paid for thru your property taxes, free water quality testing and no power outages.
Quite the novelty for me!

The commercial, industrial, and residential tax base far, far exceeds that of the VI.

The FL cruise ship tax base alone is probably bigger than the VI economy.

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).

There have been rumors circulating about the continued investment and progress taking place at Lime tree. Does anyone know for sure, have they moved any closer to bringing parts of the refining operation back on-line?

Not for sure, but lots of anecdotal evidence; hiring, pipe plugs being pulled out, building rentals, etc.
Jet Fuel refining is the latest rumor.

I need clarification. Weren't Cottage and Blessing turned over to the VI in the sale agreement? Presumably the Government can rent them to anyone?

Cottage and Blessing did transfer to VIG Property and Procurement, and Limetree leases the houses for employees.

Thanks for the clarifications. I'm glad the VI Gov is not responsible for the maintenance; otherwise the houses would become a pile of rubble by the end of the decade.
