Energy Efficiency

• Energy Efficiency (EE) is the best way to achieve
  some of the goals within the 2020 Petrobras
  Strategic Plan
• Contributes to GHG emission reduction
• Reduces the impact of resource usage (more
  sustainable)
• Energy Efficiency is good for the business
• Reduces unit production costs
• Improves the companys image with its investors
  and society
• Bovespa Corporate Sustainability Index
• Dow Jones Global Sustainability Index
• Pro-Gender Equality Program
• UN considers Petrobras' Social Environmental
  Balance notable

Importance of Energy Efficiency

• Petrobras is growing (new oil fields are being
  discovered)
• Petrobras is the largest single energy consumer
  in Brazil
• Petrobras social commitment to reduce GHG
  emissions and also to make more energy available
  to support the countrys growth
• By 2020 Petrobras intends to become a reference
  in Energy Efficiency

Petrobras EE Main Programs

• Thermo Integration Program
• Co-generation and combined cycle
• Turbo Expanders
• Advanced Control
• Modernization of existing sites

14
Modernization of existing sites

• Focus on
• Boilers and Fired Heaters
• Soot blowers
• Air preheaters
• Combustion Analyzers
• Fuel Flow Meters
• Steam systems and condensed water recovery
  systems
• Cooling systems
• Chillers
• Variable Speed Drive (VSD)
• Automatization and Control
• Optimization of Energy Balance
• Advanced Control Systems
• Thermo solar heating

15
Example of Soot Blower
Soot accumulates on the walls inside the fired
heater reducing heat transfer efficiency
The soot blower cleans the fired heater
reestablishing high heat transfer efficiency

Optimization of Energy Balance

• Consideration of refinery complexity
• Simulation to preview energy consumption and
  generation requirements (Energy Balance) before
  and after implementing new units
• Consideration of refinery flexibility
• Diary optimization of Energy Balance

18
Advanced Control in NGPU

• Implementing in 16 units
• 3 of them are implementing regulatory controls
• Expected Benefits
• Reduce energy consumption (2 to 10)
• Maximize recovery of high value products (2 to
  10)
• Increase processing capacity (around 5)
• Assure product specification
• Stabilize processes
• Minimize flaring (product lost)
