Portable Natural Gas Odorizer
Welker’s compact portable injection odorizer is your safeguard against emergency interruptions to operation. When your primary odorizer is down, time is of the essence. The Portable Odorizer provides temporary, time-based odorization for flow rates up to 6.5 MMscfh and pipelines with a maximum operating pressure of 2,000 psig.
Features
- Mounted on a two-wheel hand truck that can be easily navigated across bumpy terrain
- Has a relatively small footprint, which allows easy storage when not in use
- Includes flexlines with quick-connects, requiring minimal effort and easy installation
- Made from strong, lightweight, and rust-resistant material making it stable and durable
- A fold-up step provides a convenient platform for the customer-supplied odorant supply tank, keeping system connections short for optimal operation
- No auxiliary gas required; use unodorized upstream gas to supply the pneumatic timer and apply blanket pressure to the customer-supplied odorant supply tank
Accu/Line™ Odorant Injection System
Welker’s Accu/Line™ turnkey natural gas injection odorization solution for flow rates from 10 Mscfh up to 7 MMscfh and a maximum operating pressure of 1800 psig.
Receiving feedback from the customer gas flow meter and system odorant flow meter, the controller adjusts the injection rate to changing flow conditions, ensuring continuous proportional to flow odorization. Measuring every pump stroke volume to an accuracy of 0.002 cc, the system odorant flow meter guarantees precise odorant injection.
Features
- Two odorant injection pumps of different volumes to improve system responsiveness to variations in flow rate
- Identical redundant pumps with automatic failover to limit interruptions to operation
- Prolonged operational life and reliability due to contaminant removal
- Monitor real-time data on-site with the intuitive touchscreen controller or remotely
- Time-stamped audit data is backed up to an SD memory card for accurate reporting and planning
- Comes with 110% containment sloped to the drain to protect against contamination and ease cleanup
- Odorant supply tank can be sized to suit a broad range of flow rates
PulseInject™ Odorant Injection System
Welker’s patent-pending pumpless, pressure-driven odorant injection system is a complete solution for proportional to flow odorization for flow rates from 25 Mscfh up to 8 MMscfh and pipelines with a maximum allowable operating pressure of 1480 psig.
Features
- Low maintenance with reduced interruptions to operation
- Prolonged operational life and reliability due to contaminant removal
- Off-site system monitoring and data recording
- Uses low differential pressure and solenoid operation to odorize
- Adds the real-time liquid odorant measurement of our standard injection system, allowing the Programmable Logic Controller (PLC) to continue proportional to flow odorization when flow conditions change
ECOsystem™ Pumpless Vapor Injection System
The Welker ECOsystem™ Automatic Bypass System supersaturates carrier gas in an odorant tank to properly odorize natural gas pipelines. Our design uses differential pressure to odorize your gas line while minimizing moving parts and maintenance on the system. Since odorant is vaporized before infusing with the gas, it bonds more effectively than when injecting odorant in liquid form.
ECOsystem™ eliminates the need for manual valve operation while also ensuring precise proportional to flow odorization. The incorporated Programmable Logic Controller (PLC) receives output from the flow meter on the pipeline and the system flow switch and adjusts the odorization rate accordingly. As seasonal and environmental factors impact the gas flow rate, accurate proportional to flow odorization continues—no crude valve adjustments required.
Features
- Properly odorizes gas pipelines with supersaturated carrier gas (vaporized odorant)
- Reduces maintenance with fewer moving parts
- Automatically adjusts injected odorant to match flow rate
- Monitor real-time data on-site with the intuitive touchscreen controller or remotely
- Time-stamped audit data is backed up to an SD memory card for accurate reporting and planning
