The required flare gas pressure for Sonic Flare systems will depend on the application. Gas production or processing applications typically require 3.5 to 5.5 bar. In this case, Samia Italia recommends a sonic flaring system, which would potentially eliminate the needs of any smokeless system. Petrochemical applications typically require 1.3 to 1.7 bar. In this case, Samia Italia recommends using a ground flare system.
