Section 3: Filling the Bulk Odorant Tank
Filling the Tank for the First Time
CAUTION:
Odorant has a very strong odor, which if allowed
to escape into the atmosphere may cause
problems in the local community. Take necessary
precautions when filling an odorant storage tank
to assure that the local community is not
disrupted during the filling process. Verify that
the entire system has no pressure in it before
beginning. Additionally, all personnel should
wear protective clothing, and use equipment as
recommended by the chemical manufacturer
during this time. If you are uncertain about any
aspect of the odorant itself, you should contact
the manufacturer of your chemical prior to
proceeding.
The MAXIMUM amount of odorant
in the standard tank should never exceed 4
gallons.
1. Verify correct position of valves before begin-
ning,
figure 5
.
Closed: V10, V11 and V13
2. Attach inert or natural gas supply to V10.
3. To purge the tank open valve V10 to introduce
inert or natural gas to the tank to begin dis-
placing any ambient air from the empty tank.
Continue until pressure on the gage located
directly below V10 is observed, then partially
open V11 to allow ambient air from the tank to
begin flowing out. Allow this process to continue
until all ambient air from the tank is purged, and
only inert gas or natural gas is emitting from
this valve, then close V11 and V10. The time
required to accomplish this task will vary with
the tank size.
4. Vent purge gas by opening V11 partially until
tank pressure just reaches zero, and then close
V11.
5. Attach odorant supply to V10, open V10, and
begin transferring odorant to the bulk tank.
• The tank level indicator will not start to
rise until approximately 0.5 gallons of
odorant is in the tank.
• 1 gallon is approximately the thin line
above the fitting.
• 2.5 gallons is approximately the next thick
line below the red keep-out.
• 4 gallons is about where the red diagonal
keep-out mark starts.
6. Connect a line from V11 to a flare or vapor
recovery device, and open V11.
CAUTION:
Fill tank to a maximum level of 80% of the tank
capacity (4 gallons). Stay below the red-diagonal
keep-out.
7. Close V10 and V11, and remove odorant
transfer equipment, and line to flare or vapor
recovery device.
8. Continue through the remaining procedures in
this manual.
