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.
1. Verify correct position of valves before beginning,
figure 15
.
Open:
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
.
Section 3: Filling the Bulk Odorant Tank
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 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 recov-
ery device, and open
V11
.
CAUTION:
Fill tank to a maximum level of 80% of the tank capacity.
7. Close
V10
and
V11
, and remove odorant trans-
fer equipment, and line to flare or vapor recovery
device.
8. Continue through the remaining procedures in this
manual.
