In the complete paper, the authors describe an extremely low-BTU (ELBTU) flare-tip technology designed to help the oil and gas industry achieve net-zero targets. The operator embarked on a joint research and development project to address the limitations of high-heating-value requirements by designing the technology. The prototype was proved to successfully combust lower-heating-value flare gas, significantly outperforming existing technologies.


The joint research and development project began work in 2018. The development of the described technology began with a literature survey on lean-gas-combustion theory. The project included multiple iterations of prototype design, simulation, and testing, with various parameter adjustments to optimize performance while considering a thorough range of combustion criteria.
