Here is update on ExxonMobil 348 MBD Beaumont Refinery (8 drum) 45 MBD coker – where another coke drum (No4) was forced down due to crack that requires repairs. (~Jan. 2011 news items)
There are 2 sets of 4 drum units (older one 26 MBD & one installed in ~90’s @ 19MBD = for combined 45MBD total) operating at XOM Beaumont with the newest 4 drum unit being added 2 drums at time starting in ~1992 (by Brown & Root?). So I would expect No4 drum to be part of the older coking unit.
COP technology was used on XOM’s Baytown & Baton Rouge cokers but I don’t have license info on who did XOM’s Beaumont cokers.
According to my records they also have had coke drum crack in No5 in 2/21/08, and on No 7 coke drum in 9/15/09. And I don’t have drum number but there was also a S/D for crack developing on 5/22/09 as well. This seems like a lot problems for these coke drums?
