Fenceline Update

July 23, 2008 at 9:53 am · Filed under Maintenance

I’ve edited the data reporting website with the following changes:

  • Added Methane,  Mercaptan, and MTBE to FTIR listings.
  • Changed the FTIR readout to PPB to be consistent with the UV instrument.
  • Made the FTIR data fields turn green on non-zero reading (as the manufacturer claims that a non-zero is a detect).
  • Changed the FTIR signal strength and MET Temperature data fields to “NA” until they are available.

See the changes at http://fenceline.net/fence.php and let me and Don G. know if the numbers make sense to you. The charting doesn’t seem to work yet on the FTIRs.  We might need more time for more data….

Regards,

ET

Fenceline Status and update

July 19, 2008 at 6:31 am · Filed under Maintenance, Outages

Hi all,

As discussed at the 7/10/08 fenceline meeting at the refinery, the following items are to performed by Don G’s company ASAP:

  1. Get methane and mercaptin back on the FTIRs.
  2. Change the reported levels to PPB on the FTIRs.
  3. Provide thresholds for detection for FTIR Chems for modification (green boxes enabled) to the website.
  4. Send signal strength data to website from FTIRs. (old item)
  5. Get temperature data back to the website. Met tower to be erected.

Also, apparently the North FTIR has been NON-FUNCTIONAL for the past four days.  Please advise.

Please make additions and corrections to the comments.

Thanks,

ET

7/6/08 release

July 7, 2008 at 5:59 pm · Filed under Alerts and Emergencies

Sunday night there was a one hour upset of a CP sulfur unit. Odor
very strong around Vista del Rio, but only light fleeting in Tormey.
Air Qual. responded to call on a Sun. night. Did anyone else smell
anything between 8 and 10?
I felt it was a mixture of SO2 and H2S. Here’s a time line:
North fence line picked up a sharp doublet for SO2 lasting between 8
and 9 PM. Maximum of 325 ppb.
Confirmed by BAAQMD SO2 monitor in Crockett with 196 ppb avg. for 9
PM and 78 ppb for 10 PM reading.
We got strong odor at 8:30 on Kendall.
CP called in Level 1 warning at about 8:45. But chose not to activate
sensitive receptor list.
