thermal NO X in vapour combustion service. A lean premix solution proved to be the best answer, as it yields a reduction in the peak flame temperature, which dramatically reduces the production of thermal NO X in this application. Home-grown solution The company set out to test and develop a lean premix technology that would have all of the aforementioned advantages. The initial goal was to reduce NO X in vapour combustion service from 0.15 lbs NO X /million Btu to 0.02 lbs NO X /million Btu. To do this, multiple conceptual designs were researched and tested at John Zink's headquarters in Tulsa, Oklahoma, US. Ultimately, the solution that came to be named as NOxSTAR TM vapour combustion technology proved to be the most safe, effective, and reliable. The technology builds on traditional vapour combustion technology, incorporating anti-flashback burners, pressure-staging control, flashback arrestors, and reliable energy-efficient pilots sighted with interlocked flame scanners. Defeating NO X formation The vapour combustion system is a robust solution for many services including ship/barge loading, truck/railcar loading, and tank venting applications. It has been designed to utilise multiple fuel gas types and achieve the same performance standards. The technology is suitable for terminal users requiring low NO X and high destruction efficiency all while achieving high stack capacity and greater than 10:1 turndown. High heat capacitance in a single end control device often eliminates the need to stage multiple end control devices, making regulatory compliance testing much easier. NO X my problem As production reaches new heights and crude oil export policies evolve, meeting new throughput levels will become ever more challenging for US terminals. Now, more than ever, reducing the magnitude of NO X emissions through vapour combustion technology is imperative. With new solutions such as NOxSTAR vapour combustion technology, the US crude oil export market can avoid bottlenecks in throughput – and profits – to take advantage of the favourable economic climate.
