Carbon Footprint Analysis Methodologies and Insights

• Understanding the carbon footprint of a refinery is crucial in today's sustainability-focused world.

• Methodologies: Data collection on energy usage, fuel types, process efficiency, and emissions control. Emission calculations using emission factors based on (ones through without recycle) unit throughput. Integration and analysis for insights.

• Insights: Identify emission hotspots, assess environmental impact, and develop strategies for emissions reduction.

Scope of Analysis

• Scope 1: The analysis encompasses various factors, including direct emissions from combustion processes, flaring, and venting, as well as indirect emissions from energy consumption.

• Scope 2: Steam and electricity consumption and production are key components considered in the analysis.

• Scope 3: Overhead, e.g.: Upstream and downstream transportation and distribution, use of refined products, end-of-life treatment of waste materials, Employee commuting and business travel

Steam Consumption Analysis

• Assess the sources of steam (e.g., boilers, heat exchangers) and their associated emissions.

• Consider the efficiency of steam generation processes and the carbon intensity of the fuels used.

• Calculate CO2 emissions attributable to steam consumption.

Electricity Consumption Analysis

• Examine electricity usage across various refinery operations.

• Identify the sources of electricity (grid, onsite generation) and their emission profiles.

• Quantify CO2 emissions resulting from electricity consumption.

Crude and Product Slate Analysis

• Crude Slate: Assess composition and impact on carbon footprint. Heavy crude increases emissions due to energetic processing.

• Product Slate: Examine refined products and their environmental impact. Identify opportunities for optimization.

Integration and Analysis

• Integrate emissions from steam and electricity consumption with other sources to derive the refinery's total carbon footprint.

• Analyse emission trends over time and identify areas for improvement.

• Compare carbon intensity metrics with industry benchmarks for benchmarking and goal setting.

Insights and Opportunities

•Gain insights into emission hotspots and areas for emissions reduction.

• Identify opportunities for efficiency improvements, fuel switching, and renewable energy integration.

• Develop strategies and initiatives to mitigate emissions and enhance environmental performance.

• For CO2 rich waste streams consider carbon capturing, greenhouse injection to increase crop growth.

• Graphene membranes could help to recover CO2 from CO2 rich waste streams in the near future.
