Innovation Solution
A transportable forced air elevated flare system built on a trailer, featuring a self-contained design with a pilot assembly, air tube assembly, burn gas assembly, and control system, which allows for quick setup and operation, achieving over 98% burn efficiency and ensuring the thermal destruction of H2S and other toxic compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If existing gas flare technologies are used, then they can dispose of gas, but they lack portability and require heavy equipment like cranes for setup
Solution Approach 1:
The flare system is divided into modular components including a burn tube assembly, support legs, air injection system, and control system that can be independently transported and quickly assembled on-site, eliminating the need for heavy lifting equipment
Solution Approach 2:
The flare system incorporates adjustable support legs and movable components that allow the structure to be easily configured and repositioned at different locations, providing dynamic adaptability without requiring fixed installations or heavy equipment
2Reliability
If conventional flare systems are used, then they can burn gas, but they fail to achieve high burn efficiency and destroy toxic compounds like H2S
Solution Approach 1:
The system uses forced air injection through the burn tube to create high-velocity combustion zones that raise flame temperatures sufficient for thermal destruction of H2S and other toxic compounds, achieving over 98% burn efficiency through pneumatic enhancement
Solution Approach 2:
The forced air injection system provides concentrated oxygen supply to the combustion zone, accelerating the oxidation process and enabling complete combustion of hydrocarbons and thermal decomposition of toxic compounds at higher rates and temperatures
3Adaptability or versatility
If portable flare systems are used, then they can be moved to different locations, but they lack self-contained features and require external equipment for operation
Solution Approach 1:
The flare system integrates multiple functions into a single self-contained unit including the burn tube, air injection system, control system, and support structure, combining what would traditionally require separate external equipment into one portable assembly
Solution Approach 2:
The flare system is designed with universal features including adjustable support legs for various terrains, multiple connection points for different hose types, and a control system that can operate with different gas sources, enabling deployment in diverse field conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a portable, efficient, and safe means to dispose of gas and oil well site gases, ensuring high burn efficiency and effective destruction of toxic compounds without the need for cranes or heavy equipment, enhancing operational flexibility and environmental safety.
Implementation Method 1
The burn tube allows the gas and air to mix sufficiently for a clean burn
Implementation Method 2
This mixture of air and burn gas is then ignited by the ignitor and burned off inside the burn tube
Implementation Method 3
The air for the assist air flow is pulled from the environment and blown into the air tube using the blower
Implementation Method 4
A clean burn is a burn with a high enough temperature to thermally destroy any H2S and other toxic and carcinogenic compounds

AI summary
The Portable Flare is comprised of a pilot assembly, an air tube assembly, a burn gas tube assembly, a flame tube, a control system, a transport assembly, and a hydraulic lift. The pilot assembly is comprised of pilot gas supplied from the well site, a pilot gas supply line, a low-pressure regulator, a pressure measurement tap, a valve, a burner, an ignitor, and a pilot thermocouple. The temperature of the flame is controlled by monitoring the main burn thermocouple and adjusting the air flow with the blower that forces air up the air tube to mix with the burn gas.
