GPL 5000 Natural Gas and Propane Odorization
The GPL 5000 is an advanced odorizer ideal for natural gas and propane odorization, particularly in high-flow stations at low pressures. The odorizer utilizes proprietary patented technology and has high rangeability (512:1), delivering extraordinary high and low flow accuracy.
Product Overview
Odorization for Up to High Flow at Low Pressure
Similar to the GPL 750, the 5000 uses differential pressure to drive the odorizer, not gas, thereby saving pipeline gas. Also, the odorizer has odor-free operation and maintenance, and a sealed-loop system means the unit is emission-free, never discharging gas or odorant into the atmosphere.
The GPL 5000 can odorize biogas or biomethane also. It’s appropriate for municipalities, small city gate stations, and large stations if at low pressure.
Batch Odorant Injection for Pipelines:
1 to 400 PSI (1-27.6 Bar) Standard
No Flow to 512.8 MMSCFD*
(*injection rate of 0.5 lb./MMSCFH)
Features & Benefits
An industry-leading PLC has a large intuitive touchscreen making controlling and monitoring the system simple. The system interfaces with Modbus (SCADA). Setting up audit trail reports for company programs or regulatory compliance is uncomplicated. Also, a Spanish mode is available upon request (GPL custom programming).
Real-time mobile alerts to smartphones and computers using a wireless modem make monitoring the system simple, stopping minor issues from becoming big problems and speeding up restoration time.
