Saudi Aramco wins flare optimisation award

Saudi Aramco’s Yanbu’ Refinery Department (YRD) was recently awarded the International Green Apple Environment Award for its initiative ‘YRD Flare Optimization by 57%’. This is the first time a Saudi Aramco department has won the award.

The initiative was evaluated thoroughly by Green Apple subject matter experts and was ranked by judges as the third best environmental best practice implemented in 2017.

Winning this award is aligned with YRD’s vision to become a model refinery by 2020 through the implementation of new technologies and initiatives, thus enhancing its environmental, energy and financial portfolios.

The Green Apple Environmental Award Program is organised by the Green Organization, a prestigious international, independent, nonpolitical and nonprofit environmental platform in the world. The organisation’s main focus is on promoting, rewarding, and sharing best practices for both industrial and non-industrial environmental activities.

The flare optimisation initiative was achieved by constructing a new jump-over line connecting the normal flare to the sour flare header, and building a control logic to govern the purge gas process between the two flare headers. This has contributed to reducing YRD’s total purge gas rate dramatically from 340 million ft3/yr down to 192 million ft3/yr, which has translated to a revenue generation of US$650 000 annually.

Furthermore, this initiative has also contributed in limiting the YRD emissions footprint by a total reduction in sulfur oxide and nitrogen oxide emissions of 4500 kg/yr and 6000 kg/yr, respectively.

Winning a Green Apple Award is another demonstration of the compnay’s commitment to implementing and maintaining best environmental practices, and in line with the global trend of reducing harmful emissions in the refining industry.
