Gas Assisted Flares

Gas Assist flare systems are a great option for any application that requires smokeless flow but either does not have power at the site, or assist gas is preferred instead of using rotating equipment. Cimarron’s Gas Assist flare systems are on the cutting edge of flare technology when using the proprietary DRE MAX® control system. This combination of Gas Assist + DRE MAX® allows for on-demand assist gas, rather than the traditional continuous flowrate of assist gas. The on-demand functionality only uses assist gas when needed and adjusts the flow to only use as much as needed for any specific flowrate. This proprietary functionality of Gas Assist + DRE MAX® significantly reduces the utility costs while also reducing emissions. This combination provides the most efficient and also the highest DRE performance, of any Gas Assist flare system in the industry.

  • DRE MAX® Advanced Controls & Energy Efficiency

    Automated Assist Gas Control: DRE MAX® is the answer for operators who have a gas assisted flare. Traditional gas assist flare systems require a steady flowrate of assist gas to the flare system 24 hours a day. The assist gas does not vary as the waste gas flow rate varies, wasting assist gas when not needed and significantly increasing utility costs. DRE MAX® ensures that the optimized amount of assist gas flow is always automatically sent to flare by modulating the assist gas as-needed, to ensure the highest destruction efficiency and stay in compliance.
    Decrease the total amount of emissions by half: Because DRE MAX® modulates the assist gas flow as the waste gas flow varies, it decreases flare emissions by at least 50% compared to traditional assist gas flares. As a result, gas-assisted flare with DRE MAX® can significantly reduce gas consumption and reduce emissions at the same time.

  • How It Works

    Gas Assist flares can be employed at sites where steam may not be available, gas pressure is not high enough to utilize pressure assist, and power is not available to run a blower. Gas assisted flares are also used to enrich the waste gas in cases where the net heating value of the gas is not enough to guarantee stable combustion. In this case the assist gas can either be injected at the flare header or into the flame zone via the assist gas nozzles.

    Gas assist flare tips combine assist gas with the waste gas stream at the flare tip exit to deliver smokeless combustion over a full range of flow conditions. The assist gas is flowing at sonic velocity through the assist gas nozzles and the momentum helps inspirate ambient air to ensure complete combustion.

    • Smokeless flow over full range of flows
    • Stable and reliable combustion due to assist gas ring providing a concentric ring of high-pressure injection.
    • Enriches low BTU waste gas streams with high CO2 content to ensure combustion

  • Design Parameter Considerations

    • Inlet Gas Temperature: Standard packages utilize carbon steel gas risers that can handle temperatures ranging from -20°F up to 600°F+. Low-temperature carbon steel can be utilized as a cost-effective solution for temps down to -50°F. For gas that is colder than -50°F, stainless steel process pipe is used.
    • Inlet Pressure: Flares can handle a range of inlet pressures up to 50 psig. The standard steel piping of the gas riser can structurally handle pressures higher than 50 psig, considering that flare systems are open to atmosphere and do not retain pressure. However, there is potential for the flare tip flame to break away or lift off form the flare tip at pressures higher than 50 psig. Special design considerations can be utilized at pressures higher than 50 psig to fit your specific needs.
    • Assist Gas Pressure: To ensure smokeless combustion, the assist gas velocity needs to be at sonic flow. This requires the assist gas pressure to be set at 12 psig or higher
    • Assist Gas Piping: To ensure smokeless combustion, the assist gas piping upstream of the flare needs to be equal to or greater to the diameter of the assist gas valve train and line included with the flare system.
