Valero hydrocracker shutdown / startup

Valero to shutdown the hydrocracker again but it can’t last any longer than 10 days (due to the catalyst).  Valero have reported no complaints.  LDEQ monitored on 5/09/2013 downwind on Jacobs Dr and no readings were above the detection level of 100 parts per billion sulfur dioxide.  SO2 levels below 100 ppb are not detectable on these specific monitoring devices.  LDEQ reports a noticeable odor.  LDEQ update on 5/12/2013 reports a new sulfur dioxide release of approximately 400 pounds SO2 per hour.  This incident was reported to be secured but with ongoing flaring.

UPDATE: May 17 2013 hydrocracker release ongoing and emissions estimated to be above reportable quantities. As noted in early March 2013, Valero has determined the hydrocracker/hydrotreater unit canot be started up as currently designed without venting a quantity of H2S containing gas to the flare. http://edms.deq.louisiana.gov/app/doc/view.aspx?doc=8802780&ob=yes&child=yes

UPDATE: May 17 2013  Sulfur recovery unit tripped , release from heater stacks of VOCs, SO2, and H2S.  Air monitoring is non detect (? not above 0.5 ppm or not above 0.1 ppm depending on device utilized).

 May 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,17 2013 flaring.  Sulfur dioxide readings in Meraux reflect the emissions.  Spikes in hydrogen sulfide and sulfur dioxide at both sites correlate to the night time pattern of noise.  High pitched, high frequency type noises audible in homes May 7 11pm to May 8th 3am.  sleep deprivation again for the neighborhood.  high frequency cycling and high pitch tones early morning and throughout day May 9 with evening flaring
