Pipe Flares are unassisted equipment designed to combust hydrocarbons where non-smokeless operation is environmentally acceptable or where the waste gases produce little or no smoke due to their composition.
AMMONIA AND CO2 FLARES
Special design tips should be considered when flaring ammonia at cold temperature or when it becomes necessary to increase the combustion efficiency of a weakly combustible gas mixture such as those containing carbon dioxide.
STEAM/WATER/AIR ASSISTED FLARES
Depending on the waste gas composition and utilities available for the flare, steam or air assisted tips can be used to increase the mixing and the air entrainment, actively promoting smokeless combustion of low pressure waste gases. Typically on remote sites where steam is not available for a flare, an air assist technology is a viable option to achieve smokeless combustion. To attain best efficiency, the tips are CFD (Computational Fluid Dynamics) evaluated for optimal performance.
Depending on the operating temperature of the flare gas, location, overall height, plot plan constrains and deflection limits set forth by Project specifications, we can provide the most cost effective design selecting between self-supported, guy wired and derrick supported flare stacks.
SONIC / HIGH PRESSURE FLARES
When the waste gas is delivered at high pressure, sonic flares can be proposed in order to achieve smokeless / low radiation flaring, converting the internal energy of the high pressure gas in kinetic energy therefore increasing mixing and air entrainment. Multipoint sonic flare technology reduces low pressure zones and burnback inside the flare to increase efficiency and extend flare tip life.
