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 recom-
mended 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.
1. Verify correct position of valves before beginning,
figure 19.
Open: V12, and V13*
Closed: V10, V11, and V15
*Note Gas Supply to V13 should NOT be turned on
during this procedure.
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 displac-
ing any ambient air from the empty tank. Con-
tinue until pressure on the gage located directly
above V13 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.
6. Connect a line from V11 to a flare or vapor recovery
device, and open V11.

7. Close V10 and V11, and remove odorant
transfer equipment, and line to flare or vapor recovery device.
8. Turn Gas Supply to V13 on, and open V13 and V15.
9. Continue through the remaining procedures in
this manual.
