Odorizing sistems
Sistema di odorizzazione Odotronic a iniezione
CPL Concordia produces two different odorizing systems:
- Odorizing injection systems
- Lapping odorizing system
Odorizing injection systems
The odorizing injection system was specifically designed to guarantee a constant odorization rate regardless of the gas flow rate, the type of odorizer employed, and the required odorization rate.
The odorizing systems used up until now have several disadvantages from the point of view of operation as well as safety, as summarized below:
- Very low precision
- Difficulties regarding calibration and regulation
- Low operational flexibility
- Difficulties in communications between men and machine
Our system solves all of these problems and permits gas to be easily and safely odorized.
The lack of precision inherent to the lapping system is compensated for by the system’s operating principle. The electronic regulator receives the amount of gas dispensed and the amount of odorizer injected and, based on its programming parameters, it sets the number of impulses to be sent to the injector or the metering pump to guarantee the set odorization rate.
Lapping odorizing system
The odorizing system's functioning is based on a property that is common to all substances in the liquid state: the production of a certain amount of vapor. Basically the system consists of a tank with a certain capacity, two connectors for connection to the main methane gas line, two connectors for adding odorizer, two connectors for the level, a connector for emptying the tank, a reinforced (reflection, magnetic) stainless steel level gauge, and a containment tank.
All the system's parts are made of materials that are resistant to chemical reactions with the odorizers: carbon steel for the tetrahydro-thiophene-based odorizer and AISI 304L stainless steel
for the mercaptan-based odorizer. PTFE packing is used.
The choice of the odorization system is tightly correlated to the typology of the plant:
- Odorizing injection systems is the solution for the big installations
- Lapping odorizing systems is ideal for small-medium installations
