ODORIZING SYSTEM
Natural gas leaks from the transport and distribution networks must be immediately detected in order to avoid possible accidents caused by the fact that gas is flammable, explosive and toxic.Natural gas is odorless; therefore, it is necessary to add an odorous substance to detect its presence in the air.the odor must be strong enough to be detected before reaching the lower explosive limit (lowest concentration in percentage og ga in air capable of producing a flash of fire in presence of a source of ignition)-5% for natural gas.
INJECTION ODORIZER:
BY-PASS ODORIZER:
The By-Pass odorization of a gas flow (Evaporation Absorption) involve establishing a small side flow of gas, saturating the small stream with odorant vapor and returning it to the main stream. Consideration must be given to the flow control of the small stream, the temperature of the saturating vessel, and the type of odorant used.
Typical Application
The evaporation-absorption (By-pass) Odorizer consists of a tank equipped with one or more wicks located on a by-pass gas line. The control for bypassing the gas through the tank is obtained by manually throttling a valve located on the main line.
