P-66, P-70 and P-77 have reduced gas flare

(TN) Platforms P-66, P-70 and P-77, located in the Tupi, Atapu and Búzios fields, respectively, started to operate with minimal flaring of gas, which starts to occur only in exceptional safety situations, reducing the emission of greenhouse gases (GHG). The flare is the equipment that has the function of burning the gas not used in the platforms, in order to dispose of it in a safe way. The start-up of the flare gas recovery system (FGRU or Flare Gas Recovery Unit) allows this gas to return for processing in the unit, preventing its burning and the consequent emission of greenhouse gases. The potential for reducing emissions using the system on these three platforms is around 80,000 tons of CO2 equivalent per year.

In addition to the P-66, P-70 and P-77, Petrobras will start operating, in 2022, the gas recovery systems of eight more platforms in the Campos and Santos Basins.

 The use of the flare gas recovery system is one of the company’s vectors for reducing greenhouse gas emissions in production activities. The initiative will help Petrobras achieve four of its sustainability commitments, set out in the Strategic Plan: the 32% reduction in the intensity of greenhouse gases in exploration and production (E&P) operations by 2025, the zero routine flaring by 2030, a 40% reduction in the intensity of methane emissions in E&P by 2025, and a reduction in absolute greenhouse gas emissions by 25% in 2030 compared to 2015.

“All the new projects of units owned by Petrobras already have the gas recovery system by default and we started to adopt it also in the specification of chartered units. In addition, with the recent revision of CONAMA resolution 382, ​​we will have a new generation of projects for platforms with high production capacity in the all electric configuration, contributing even more to the reduction of greenhouse gas emissions”, informs Carlos Travassos, manager executive of Surface Systems, Refining, Gas and Energy. The all electric configuration is more efficient and allows for the use of less fuel to generate energy on the platform, as all equipment will be driven by electric motors, using electrical energy generated centrally. In the current configuration, power generation is decentralized because compressors that burn natural gas are also used as an energy source.

“Today we produce oil with low carbon emissions thanks to an improvement of almost 50% in our efficiency since 2009. Specifically in relation to methane, which is one of the gases that most contribute to the greenhouse effect, we had a reduction of more than 35% emissions in the last 10 years. The use of the flare gas recovery system, among other measures, will help us to pursue maximum efficiency, as close to zero as possible”, highlights Viviana Coelho, executive manager of Climate Change at Petrobras. The company seeks to operate with low costs and low emissions, which will allow it to be competitive to act in scenarios of accelerated energy transition and in line with the Paris Agreement.
