Natural gas odorizing unit

PF odorant injection systems can manage different types of odorant, such as TBM and THT, guaranteeing a constant odorization ratio at every gas flow rate.
Depending on system requirements, injection may occur either by means of solenoid valves or by a volumetric pump.
In case of solenoid-driven systems, a connection with the high-pressure section of the plant provides the required pressure to inject the odorant into the gas line; regulation of amount of odorant are obtained with micrometric valves and opening time of the solenoid valve.
All systems are provided with a dedicated control unit to manage process parameters, acquire the signals from the metering equipment in the plant and adjust the amount of odorant injected on the base of gas flow.

In pump systems, the pump gives the required pressure to inject the odorant into the gas line. The minimum quantity of odorant injected can be set by tuning the stroke of the pump.
The odorant storage tank can be used also as backup system in case of system failure. Part of the gas is sent through the storage tank and, by lapping the surface of odorant, the gas takes away a quantity of odorant into the main stream.
