Monaca, Pa!

Shell Chemical has selected the Pittsburgh area town of Monaca, Pa., as the site of its new ethylene cracker complex. Actually it will be in Potter and Center Townships, which are near Monaca, Pa. (Pop. 6,286, according to Wikipedia). But that narrows it down a lot more than what Shell was previously saying: “I don’t know, Appalachia somewhere or something.”

Monaca is a bit of a chemical town. It is host to a Nova complex that makes Arcel polystyrene resins for foams and expandable polystyrene. Nova calls this the Beaver Valley site. (If that name conjures an image of a valley teaming with beavers felling trees willy nilly, I know the feeling.)

This doesn’t mean that the plant is a done deal. As its press release explains:

“The next steps for this project include additional environmental analysis of the preferred Pennsylvania site, further engineering design studies, assessment of the local ethane supply, and continued evaluation of the economic viability of the project.”

The company isn’t saying much more about the project. It will feature an ethylene cracker and downstream polyethylene and ethylene glycol plants. We already knew about that. There’s nothing new about the size or the timing.

I do have a couple of thoughts about the project:

1) Isolated ethylene and derivatives complexes never work out. If the ethylene cracker goes down, how do you run the derivatives plants and where does the ethane feedstock go? If one of your derivatives complexes goes down, do you run the cracker at reduced rates? It would be nice to see another cracker complex built in the neighborhood that would be connected to the Shell site. I suspect that we’ll probably hear from another company with cracker plans in the region before long.

2) I doubt Shell will build its own polyethylene plant. It hasn’t had any skin in the polyolefins game since it sold its stake in Basell to Access Industries in 2005. I am expecting a partner of some kind on the polyethylene unit. If it does go it alone, I would think that the plant would spew out commodity grades of polyethylene. One example of such a product would be high-density polyethylene for extrusion blow molding—used to make milk jugs. Shell would need something that is relatively easy to sell. Also, the company wouldn’t want to do a lot of switching of grades at the plant because of potential problems with excess ethylene, as I mentioned above.

All this aside, it is great to see such a big chemical plant being contemplated for the region.
