Qatar Petroleum recovers flared gas during LNG ship loading

LNG Industry,

Qatar Petroleum’s Jetty Boil-off Gas Recovery (JBOG) project, led by Qatargas, aims to recover gas currently being flared during LNG ship loading at Ras Laffan Port.

The project will be a crucial element of the Common Facilities Projects at Ras Laffan Industrial City, as it will recover and collect boiled-off gas from LNG ships during loading. The gas will then be compressed at a central facility.

The development of the JBOG Project was initiated by QP in 2004.

Environmental investment

His Excellency Dr. Mohammed bin Saleh Al-Sada, Minister of Energy and Industry, hailed the project as one of the biggest environmental investments for LNG boil-off recovery in the world.

Commenting on the initiative, His Excellency said: “With a capital outlay of US$ 800 million, JBOG is set to become a landmark project for the State of Qatar, underlining its strong commitment to protecting the environment.”

Dr. Al-Sada stressed: “this commitment is guided by the leadership of His Highness Sheikh Tamim bin Hamad Al Thani, the Emir of the State of Qatar, as proclaimed in Qatar’s National Vision and National Development Strategy.

“The huge investment in JBOG by Qatar Petroleum and its partners will reduce the carbon footprint of the 77 million tpa of LNG production facilities to the minimum, immensely contributing to the achievement of our goals.”

LNG feedstock

The compressed gas obtained from the JBOG Project will be used by existing LNG assets of Qatargas and RasGas, either as feedstock to LNG trains or as fuel gas. The project, when fully operational, will recover the equivalent of approximately 0.6 million tpa of LNG, which is sufficient natural gas to power more than 300,000 homes. Using this flared gas, instead of letting it go to waste, will result in a saving of approximately 1 trillion ft3 of gas over a period of 30 years.

Qatargas CEO, Khalid Bin Khalifa Al Thani, commented: “We are very pleased that Qatargas is able to lead this project on behalf of all the LNG producers at Ras Laffan Industrial City. Qatargas, Qatar Petroleum, and RasGas are all focused on reducing greenhouse gas emissions and energy use so that we can reduce the wastage of gas to the lowest levels possible to meet or beat international standards. This project will contribute greatly to truly making LNG a clean fuel for the world.”

Project contracts

The Front End Engineering Design (FEED) of the JBOG Project was awarded to the Fluor in October 2007. The FEED was completed in 2008. The Engineering, Procurement and Construction Management (EPCM) contract for the project was also awarded to Fluor in February 2010.

The project design is based on collection of the LNG boil-off gas from the LNG carriers and then the transfer of this gas to a Central Compression Area via large-diameter stainless steel pipelines. At the Central Compression Area, the gas will be compressed and sent to respective LNG trains for use either as feedstock or as fuel gas. The split in compressed JBOG distribution for each LNG asset is structured based on its LNG production capacity.
