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 to 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
beginning, 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
displacing 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 1 gallon of
odorant is in the tank
• When 2 gallons of odorant is in the tank
the tank level should show approximately
1.5" on the level indicator tape.
• 3 gallons should show approximately 3"
on the level indicator tape.
• 4 gallons should show approximately 4.5"
on the level indicator tape.
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).
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.
