I know this is a little off topic, but maybe some one familiar with the old Phillips 66 culture can tell me why they chose to assign numbers to identify their process units instead of just referring to them by name? I first encountered this back in the eighties when I did some work at the Borger, TX Refinery. As I recall, one of their FCC units was unit #29 also. Since Woodriver is a recent addition to the ConocoPhillips family, it appears that the practice of numbering units has survived the merger. Have the old Conoco Refineries also gone to numbering, or have they retained their names?
