Nutara aims to be a long term partner to all our clients and provides full aftermarket support for all operation, maintenance and intervention requirements.

We can also provide for the inspection, maintenance, refurbishment and replacement of any flare system or components and can supply in some cases, rental flares during maintenance interventions.

Utility Flares (Pipe Flares) are the most basic flare design available, to provide a robust, reliable and flexible solution for the flaring of large volumes of low pressure waste gas when smokeless operation is either not required or can be achieved without an assisting medium (like steam, air or gas). Reliable operation at both full load and partial load is possible.

Key features

• Flame holders fitted on the periphery of the flare tip ensure stable operation These flame holders provide a zone of recirculated flue gases/air, which prevent flame lift off, from the flare tip
• Wind deflectors to prevent flame impingement, due to flame lick in the low pressure zone, downwind of the tip
• Pilot burner arrangement to further stabilise the flame
• Use of high grade alloys to enhance lifetime of the flare tip
• Use of dynamic seal to reduce purge gas requirements and prevent flash back

Key advantages

• Low investment and operational costs
• Low maintenance costs with the use of high grade alloys and the robust design
• Reliable and stable flaring in a wide range of operating conditions
• Large turn-down ratio

Applications

• Upstream oil & gas sector
• LNG terminals and NG compression stations
• Chemical and petrochemical industries including refineries
• Food processing industries
• Municipal solid waste treament (biogas and landfill gas) plants

Air assisted flares enable the smokeless combustion of low pressure waste gases. Air (or Gas) assisted flares can be used when no steam is available on site.

Air assisted flares use forced draft Air or Gas to create turbulence ensuring that sufficient primary combustion air is supplied to the flame.

The amount of air and hence the size of the tip and riser depend on the degree of smokeless operation required and the maximum flow for smokeless operation.

Key features

• Proprietary design to maximize the mixing of waste gas and air streams and to create turbulence in the combustion zone
• Variable speed fans, to supply the optimal amount of Air (Gas)
• Use of wind deflectors if required, to prevent flame impingement
• Flame holders around the periphery of the flare tip to ensure stable operation
• Use of high grade alloys to enhance lifetime of the flare tip
• The use of combustion/mixing air to cool the flare tip and thus enhance its lifetime

Steam assisted flares enable the smokeless combustion of low pressure waste gases at installations where high pressure steam is available. 

A steam manifold along with jets integrated in the flare tip design, inject high pressure steam into the flame.

The steam jets entrain ambient air at the base of the flame providing additional turbulence and resulting in smokeless combustion. Steam can also act as a catalyst in the overall combustion process.

Key features

• Proprietary design of the steam manifold efficiently injects steam into the flame, either internally or externally to the flare tip
• Steam Manifold is remote from the flame to lengthen the lifetime of the flare tip
• Wind shield placed around the outer steam manifold to avoid flare tip damage
• Flame holders around the periphery of the flare tip to ensure stable operation
• Use of high grade alloys to enhance lifetime of the flare tip

Key advantages

Applications

High Pressure Flares use the actual pressure of the waste gas to create turbulence, entraining combustion air into the base of the flame to obtain smokeless combustion. Nutara has a full range of high pressure flares including HP pipe fares, sonic flares and HP assisted flares. HP sonic flares are the ideal solution when low radiation along with smokeless operation are desired.

Key advantages

Applications

Industries will generate Low CV waste gases, which are either difficult to burn or can contain insufficient energy to self-sustain the combustion process.

For these applications, Nutara developed the proprietary "ring-of-fire" Flare Tip. This tip has a ring of flame around the central waste gas tip thus ensuring complete oxidation of the low calorific waste gas. Both air assisted and non-assisted flare burners are available.

Support Structures

The optimal design of flare supporting structures is dependent on many factors, including height, capacity, location, plot size, climatic conditions and riser dimensions.

Nutara can supply a complete range of support structures for non self supporting flares:
