PRELIM - PETROLEUM REFINERY, LIFE CYCLE INVENTORY, MODEL Joule Bergerson | March 11, 2015

Objectives

Motivation

• Diversity of crude quality and refinery configurations

• Current life cycle-based GHG models to inform policy lack model

detail to capture this variability

Objective

• More detailed investigation of the impacts of crude quality and

refinery configuration on energy use and GHG emissions at

refineries

Opportunities for reducing emissions

• Reduce the amount of hydrogen consumed • Increase hydrogen production efficiency • Lower the GHG emissions intensity of hydrogen

production • Capture carbon dioxide from the most

concentrated, highest volume refinery sources

Additional Insights

• PRELIM continually strives for balance between 1. Transparency and a systems perspective 2. Recognition that refineries are unique,

complex and dynamic • Extensive evaluation conducted and further

validation exercises are sought • Data is an overriding issue for PRELIM

Future Research Priorities

• A “fixed” case • More detailed assessment of refinery products

• refinery fuel gas • asphalt • bunker fuel

• Statistical analysis to explore variability and uncertainty of refinery operations and GHG emissions
