Odorizer

221001 - Gas Odorant Injection System

For low-volume and high-pressure applications at CNG filling, city gas distribution, LPG and biogas companies.

The Odorizer uses a specially designed pump and control system to deliver continuous odorant injection proportional to the gas flow.

Fully Automatic dosing proportional to gas flow rate
High range ability (100:1 turndown ratio)
Precision odorizing (1% accuracy) with a wide flow volume range
Gas flow volume from 100 SCMH to 100000 SCMH
For pipelines with pressure 5 – 4500 PSI (0.3 – 300 Bar)

The Odorizer uses pipeline gas with regulated pressure to activate the system. It is pneumatically operated, hydraulically isolated and has a clean, sealed, and vent less design.

Current Installation Lead Time: 2-4 Weeks

Zero Odorant Leakage During Operation or Maintenance

The odorant system is completely sealed & enclosed. This eliminates the common odorant leakage and associated smell complaints seen on other odorizing systems.

No Moving Parts. Long Lasting. Unlike Other Solutions In the Market

A modular solid-state manifold with minimal tube joints and no moving parts assures long-lasting performance. This also makes it extremely easy to maintain and operate.

Fully Automatic With PLC and A 7” Touchscreen HMI

The system is fully controllable via a PLC (Delta/Equivalent)
With the fully automatic mode, the machine auto-adjusts the dosing interval even if your flow rate increases or decreases. If the pipeline gas flow rate varies, the pump adjusts the time per stroke cycle to maintain a constant odorant flow.

This ensures a constant odorant concentration regardless of upstream changes to gas flow. With a maximum of 25 strokes/minute, there is virtually no risk of fluid flashing from pressure drop.

The 7” Touchscreen [Delta/Equivalent] HMI lets you intuitively monitor & control the following parameters:

Pump dosing frequency
Pump stroke count
Dosing Totalizer
Compressor ON/OFF
Dosing flow rate(Optional)
Gas flow rate manual setting/ Real Flow rate from Flow meter (optional)
Tank Level (Optional)
Tank Pressure (Optional)

Solid-State Modular Design

The Odorizer utilizes a solid-state modular designed pump assembly which minimizes joints and fittings. The hydraulic/pneumatic section of the plunger pump is isolated from the odorant section.

The only replacement items are the hydraulic piston plunger seals, engineered for long-lasting performance, and a filter to be replaced annually.

Once-A-Year Maintenance

All it needs is a new hydraulic piston seal and odorant liquid filter. And both of those are extremely easy operations.

Self-Monitoring and Real-Time Alarms

The system is self-monitoring and generates an external alarm to control room PCs and smartphones(Optional), if the odorizing system does not odorize within the configured settings. Alarm conditions are stored and time-stamped in non-volatile memory like SD card (Optional).

For whatever reason, if the system fails to dosing with the configured settings, its smart logic will send an alarm to the control room PCs and operator smartphones(Optional) in real time.
