INTRODUCTION
Scope of Manual
This manual provides instructions for installation, startup,
maintenance and spare parts ordering for the OL Series
odorizing tanks.
Product Description
Figure 1. Type OL Odorizing System
This product has been designed to be used with fuel gases of
1st and 2nd family according to EN 437, and with other non
aggressive and non fuel gases. For any other gases, other
than natural gas, please contact your local sales agent.

The odorizing systems are employed in small and
large-sized stations.
However, they are used as stand-by and emergency
systems in all injection-type odorizing installations.
For the proper operation it is necessary to reach a
differential pressure.

TRANSPORT AND HANDLING
The equipment is supplied packaged, transported in
horizontal position on transport saddles or cages.
The supports have been designed to withstand the weight
of the tank, other stresses should be avoided with proper
ligatures.
The equipment can be lifted and placed in working position
using a standard lifting systems, please avoid to attach the
lifting system to the gas / odorant nozzles.

It’s recommended the use of suitable protection to avoid
paint damages (in case of painted equipments) and also
to avoid any anomalous stress and shock on pressure
containing parts.
The transport saddles, if any, are attached to the equipment
with straps or steel cables, take care during transport to
prevent accidental saddles disconnections.
Established transport and handling procedures shall be
followed to avoid any damage to the pressure containing
parts.
Particular care must be taken to avoid any possible damage
to the pressure accessories installed on the odorant tank
(eg the level indicator).
PRESERVATION AND STORAGE
Stand-alone equipment is delivered with all nozzles blanked
and all surfaces completely protected by primer or paint
(carbon steel material versions) hence the equipment
doesn’t need specic precautions for storage, providing to
follow the recommendations listed in “Inspection” section on
page 4 of this Instruction Manual.

ATEX REQUIREMENTS
WARNING
!
If the provisions of EN 12186 & EN 12279,
national regulations, if any, and specic
manufacturer recommendations are not
put into practice before installation and
if purge by inert gas is not carried out
before equipment’s start-up and shut-down
operations, a potential external and internal
explosive atmosphere can be present in
equipment & gas pressure regulating/
measuring stations/installations.
If a presence of foreign material in the pipelines is foreseen
and purge by inert gas is not carried out, the following
procedure is recommended to avoid any possible external
ignition source inside the equipment due to mechanical
generated sparks:
• drainage to safe area via drain lines of foreign materials, if
any, by inow of fuel gas with low velocity in the pipe-work
(5m/sec)
In any case,
• provisions of Directive 1999/92/EC and 89/655/EC shall
be enforced by gas pressure regulating/measuring station/
installation’s end user
• with a view to preventing and providing protection against
explosions, technical and/or organizational measures
appropriate to the nature of the operation shall be taken
(e.g. : lling/exhausting of fuel gas of internal volume
of the isolated part/entire installation with vent lines
to safe area - 7.5.2 of EN 12186 & 7.4 of EN 12279 ;
monitoring of settings with further exhaust of fuel gas to
safe area ; connection of isolated part/entire installation to
downstream pipeline; ….)
• provision in 9.3 of EN 12186 & 12279 shall be enforced by
pressure regulating/measuring station/installation’s end user
• external tightness test shall be carried out after each
reassembly at installation site using testing pressure in
accordance with national rules
• periodical check/maintenance for surveillance shall be
carried out complying with national regulations, if any, and
specic manufacturer recommendations.
Following notes and instructions point out,
in particular, the “pressure” risk. Installation,
operation and maintenance procedures
performed by unqualied personnel may
result in unsafe operation.
This condition may result in equipment
damage or personal injury. If a leak develops
in the system, the escaping gas may
accumulate and become a re or explosion
hazard. Immediately call qualied service
personnel in case of trouble.
Hazards arising from misuse and
misoperating are:
Personal injury, equipment damage, or
leakage due to escaping gas or bursting of
pressure-containing parts may result if the
equipment is installed where its capabilities
(PS and TS) can be exceeded or where
conditions exceed any ratings of the
adjacent piping or piping connections.
To avoid this, install the equipment where:
• Service conditions are within unit capabilities.
• Service conditions are within applicable codes,
regulations, or standard.
• The unit is protected from exposure to physical damage
and/or corrosive substances.
• Suitable pressure-limiting or pressure-relieving devices
have been installed in those instances where supply
pressure is capable of exceeding the maximum allowable
downstream equipment pressure.
Materials: Odorizing tanks made of carbon steel cannot be
used for odorizing liquids containing mercaptanes.
National safety standards and established rules shall be
applied in odorizing system installation and operation,
concerning, in particular, electrical works, re, and
thunderbolt protection, safety procedures on odorisant
handling.
All means for venting have to be provided in the assemblies
where the pressure equipment are installed.
Before installation, check shall be done if service conditions
are consistent with use limitations.
INSTALLATION
WARNING
!
Only qualied personnel shall install an
odorizing tank. Odorizing systems should
be installed, operated and maintained in
accordance with international and applicable
codes and regulations.
Where this product is used:
• provide the cathodic protection and electrical isolation to
avoid any corrosion
• the gas shall be cleaned by proper lters/separators/
scrubbers to avoid any technical & reasonable hazard of
erosion or abrasion for pressure-containing parts.
Odorizing tank shall be installed in non-seismic area and
hasn’t to undergo re and thunderbolt action.
