Hart's MEA

The Environmentally Distinctive Burner is specifically designed for use in ecologically sensitive areas, where it’s critical to quantify produced emissions. It delivers industry leading burn performance & automation.

Through extensive testing and qualification, witnessed by a recognized certification authority, the Environmentally Distinctive Burner has achieved the following performance characteristics, a first in the industry:

PERFORMANCE CHARACTERISTICS
Fallout Efficiency 99.99952% Based on Fallout Target Testing
Combustion Efficiency (Carbon Converted into CO2) 99.4%* Reference EPA-600/2-83-052
Destruction Efficiency (Carbon Converted into CO2 + CO) 99.5%* Reference EPA-600/2-83-052
Carbon Dioxide Emissions 41 Ib CO2 /MMBtu* Reference EPA-453/R-11-002 & AP 42

*Exceeds EPA references

Challenge:

In order to conduct successful well tests, substantial amounts of oil must be brought to the surface and in most instances burned/flared. Traditionally, well test oil burners have always been passive equipment configured for expected conditions, but unable to adapt or react during operation. While traditional burners have been able to produce excellent steady state burn conditions, the transients, particularly during shut down, can introduce a significant amount of unburnt hydrocarbons into the environment.

Solution

The Environmentally Distinctive Burner, which offers innovative design/development solutions within its patented features. Features such as:

  1. Nozzle Control – A unique and innovative nozzle was designed which can precisely control the flow of oil and air through the burner, allowing the nozzle to be closed without any unburned fuel escaping. The nozzles are controlled remotely and powered by an integrated pneumatic system, utilizing the combustion air supply. The system is comprised of a regulator, an air amplifier, an accumulator tank, pressure safety valve, solenoids for nozzle actuation, and pressure sensors. These items, working together, allow the system to individually control the position of each nozzle.
  2. Cross Lighting - The nozzles are vertically arranged with carefully selected overlapping patterns to allow effective cross lighting of the burner nozzles regardless of wind conditions. Additionally, this flame pattern reduces the visible area of flame when observed from the rig, reducing the severity of radiant heat on the rig.
  3. Rotation - The rotation system relies on the uni-axis swivel design of the burner main body, and consists of an electric linear actuator. The electric linear actuator is programmed to adjust the angle of the burner based on the operator’s input into the portable Remote Operator Interface (ROI, touch screen interface). This enables the burner head to rotate 30 degrees in either direction from the center in 15-degree increments. This ability to rotate the burner head while-in-operation is an industry first.
  4. Burner Management System – A built in Programmable Logic Controller (PLC) contains the logic and controls for the entire burner control system, such as safe startup of operations, Individual opening or closing of nozzles to adjust flow rates, drip free shutdowns with the push of a single button within 0.3 seconds, and rotation of the burner head for changing wind conditions (± 30°).
  5. Remote Operator Interface – A real time control system that provides oil manifold, air manifold, and accumulator tank pressure monitoring, audible and visual fault alarms, and safeguards against unsafe operation.
  6. Dual Ignition System - A remote ignition and flame detection device with real time pilot status indication.
  7. Combustion air utilization for Pneumatic System – The design of the pneumatic system requires that the air compressors are function before the nozzles can be opened because the air supplied to the control system is pulled directly from the air manifold. An accumulator tank is fitted to store pressurized air, sufficient to close the burner completely, in the event that the air supply is lost.
  8. System Over-temp Safeguards – All systems are thoroughly heat shielded and some are actively cooled, additionally the ROI allows for temperature monitoring.
