Setting the standard for environmental performance

The Jetty Boil-off Gas (JBOG) Project
The “Jetty Boil-off Gas (JBOG) Recovery Project” aims to recover gas currently being flared during Liquefied Natural Gas (LNG) ship loading at the Port of Ras Laffan:

  • Reduction of 1.6 million tonnes CO2 per year equivalent to annual greenhouse emissions from 175,000 cars (there are 800,000 cars on the streets of Qatar).
  • Common facility – for all 6 Qatargas and RasGas LNG berths.
  • Anticipated completion in 2014.
  • Will recover 90% of boil-off-gas (BOG) flared at the berths.
  • Savings of 29 billion standard cubic feet per year flaring reduction which is enough to power more than 300,000 homes.

Greenhouse Gas (GHG) Management Program
Qatargas has developed a pioneering GHG management strategy, which is divided into three phases:

Phase 1 involved:
  • Understanding the GHG issue, its context and implications and developing a GHG management position.
  • Analyzing the potential impact of climate change on Qatargas’ operations and reviewing opportunities to reduce GHG emissions.
Phase 2 involved:
  • Preparing procedures, manuals and detailed externally verified emissions inventories of all Qatargas facilities (LNG Trains, Laffan Refinery, RLTO) – covering Scope 1, 2 and 3 emissions.
  • Benchmarking / establishing key performance indicators.
Phase 3 in progress:
  • Ongoing flare reduction, JBOG project.
  • Assessing carbon reduction opportunities and abatement techniques via sustainability assessment and engineering studies.Life Cycle Assessment.
  • Understanding the wider context of the benefits of LNG globally.

Wastewater Management Strategy
LNG Mega trains use desalinated water for steam generation, service water, cooling water, which eventually post-processing results in treated wastewater.
To maximize reuse of treated wastewater, Qatargas is developing the following strategies:

  • Re-Use: Suitable streams combined to meet irrigation water specifciation with minimum treatment.
  • Recycle: suitable streams combined to produce either desalinated water or polished water with appropriate treatments for recycling within the production process.
  • Reduce Disposal: significantly enhance reuse of water and by minimizing deep well injection.

Flare Reduction Program
Qatargas’ Flare Management approach will minimize flaring while providing operational flexibility and safeguarding asset integrity and process safety.
It comprises three main pillars:

  • Enhanced tracking, monitoring and reporting.
  • Operational source reduction.
  • Flare reduction capital projects.
  • Since 2009, over 65% reduction has been achieved in flaring from on-plot LNG facilities.
  • Short-term purge gas reduction and Jetty Boil-off Gas (JBOG) Recovery Projects are expected to reduce mega-train flaring by approx. 35% (from 2011 baseline levels) by 2014, with a further 35% reduction through long-term gas recovery concepts (currently under study).

Qatargas is a proud winner of the 2012 World Bank Global Gas Flaring Reduction (GGFR) “Excellence in Flaring Reduction” Award GGFR.
