Overview
Z10000 Natural Gas Odorization System
2. Overview
e Z10000 Natural Gas Odorization System is a feature-rich,
complete odorization package that avoids the operational and
functional complexities associated with other odorizers or the
odorization process. Every action is intuitive and predictable. e
Z10000 is a proven system, working reliably in some of the most
sensitive areas imaginable, including major cities that experience
blizzard conditions year aer year. Remote locations are also
accommodated as virtually everything can be taken care of via
communications features.
2.1 Principles of Operation:
e Z10000 automatically calculates and dispenses measured
doses of odorant into natural gas pipelines proportional to the
gas ow rate.
1. An odorant storage vessel is pressurized to about 25 psi.
An upstream regulator or nitrogen source is commonly
used.
2. Odorant moves from the vessel probe through the lter
to the isolation valve.
3. e controller simultaneously sends pump on command
and isolation valve open command which allows the
odorant to ow and get pumped through the Z10000
system into the pipeline.
If the controller needs to stop odorant injection into the
pipeline it simultaneously sends pump o and isolation
valve close command.
4. As the pump operates, a ow meter measures the
odorant ow rate.
5. e measured ow rate is communicated to the
controller, and the pump speed is adjusted accordingly.
6. e system controller interfaces with the ow meter, gas
ow information, local interface, remote interface, etc., to
maintain a constant odorant injection proportional to the
gas ow rate.
2.2 Continuous Mode
Continuous mode provides a constant ow of odorant into the
stream at appropriate proportions. Continuous mode is used
for gas ow rates higher than 100 msc.
2.3 Batch Mode
Batch mode periodically provides a small, metered dose of
odorant, then shuts until a sucient volume of gas has owed
to justify another batch to achieve desired injection rates. Batch
mode is used for gas ow rates lower than 100 msc.

2.4.2 System Controller
e System Controller interfaces with the Z10000 injector,
precision odorant ow measurement and gas ow information,
local interface, remote interface, etc., to maintain a constant
odorant injection proportional to the gas ow rate.

Overview
Z10000 Natural Gas Odorization System
2.4.3 Odorant Storage Vessel
e blanket pressure of the odorant storage vessel should be
kept low—less than 30 psi. Regulated pipeline gas or nitrogen is
commonly used. Odorant moves from the vessel probe through
the lter to the isolation valve (that automatically closes with
loss of pipeline pressure).
ÂNote:
A pressure regulator/
relief device must be
supplied by the customer.

testing, pipeline pressure is slowly brought back to the bulk
tank.
1. Apply nitrogen (or pipeline gas or instrument air) to
odorant supply line. Check for leaks on line leading from
the bulk storage tank to the odorizer.
2. Open isolation valve through the soware override in
TechView.
3. Check for leaks within the odorizer enclosure.
4. Open valve at pipeline to check for leaks from the
Pipeline back to the odorizer enclosure.
5. Check for leaks back to the enclosure.
6. Place isolation valve back in normal service through the
proper screen in TechView.
ÂNote:
Field wiring used for
24VDC input must be

3.7 Warm Start / Hydraulic Bleed
Aer the tubes and ttings have been leak/pressure tested
and the unit has been congured, the odorizer is ready to be
started.
1. Ensure the main odorant valve on the storage tank is
open, as well as the valve for the odorant prime/purge
return circuit.
2. Move the Inject/Purge valve (KK) to the “Purge”
position.
3. On a local display or TechView, go to the Startup Screen
and set the motor speed to 5 RPM, then enable the
motor.
4. Using the attached compression ttings on the hydraulic
bleed tool, secure the tubing of the bleed tool to each end
of the bleed valves (CC). Open each bleed valve. Gently
pull back on the syringe to create a slight vacuum on
each side of the pump. Allow the pump to run with the
vacuum, and wait until no bubbles are seen in the bleed
tubing for several minutes.
5. Close each bleed valve when the uid level on the
respective side reaches its lowest point.
6. Increase Prime motor speed to 25 RPM. Allow pump
to run again for several minutes, observing the pump
eciency.
7. Continue to run, or repeat steps 4–7 until eciency is
consistently over 85% (0.85), then disable pump prime.
8. Move the Inject/Purge valve (KK) to the “Inject” position
9. Verify solenoid override is in auto (from leak testing).
10. Turn Unit on.

4. Mechanical Overview
4.1 Solenoid Isolation Valve
e solenoid isolation valve on the
Z10000 is an electric solenoid valve.
When the solenoid is electrically
charged, it opens and allows the
odorant to ow.
4.2 Positive Displacement Flow Meter
e positive displacement ow meter is
what provides feedback to the controller to
ensure the proper amount of odorant is being
injected.

Mechanical Overview
Z10000 Natural Gas Odorization System
4.3 Hydraulic Pump
e pump is actuated by a
brushless DC servo. Its speed
varies according to odorization
requirements.
e pump actuates bellows
hydraulically. e odorant
and the hydraulic system
are separated by the bellows,
thereby allowing the entire
pump assembly to be serviced
without contacting odorant.
4.4 Bellows Capsules
e bellows capsules allow
complete isolation of wear parts
from the odorant. Inside each
capsule are the ceramic check
valves and the hermetically
welded stainless steel bellows.
4.5 Pressure Switch
e pressure switch ensures that the pump
does not run without adequate head pressure.
If the head pressure falls below 10 psig, the
pressure switch closes. is triggers the motor
controller to shut o the motor. e motor
resumes pumping once head pressure of 10 psig
is restored, opening the pressure switch.
4.6 Temperature Transmitter
e Temperature transmitter measures the
temperature of the incoming odorant,
providing compensation for
temperature induced density
changes.
