Carbon Capture Technology

Fundamentals of Carbon Capture Systems

Thermodynamics and Gas Separation Principles

• Master the thermodynamics of gas separation, including the calculation of minimum work requirements for carbon dioxide recovery from various flue gas streams.
• Understand the phase behavior of carbon dioxide and how pressure, temperature, and impurities like water vapor or nitrogen oxides affect capture efficiency.
• Analyze the solubility principles of CO2 in physical and chemical solvents, utilizing Henry’s Law and chemical equilibrium constants to predict capture performance.

Sources and Emissions Profiles

• Categorize point-source emissions based on concentration, flow rate, and pressure, distinguishing between post-combustion, pre-combustion, and oxy-fuel combustion capture environments.
• Evaluate the impact of flue gas composition—specifically oxygen, sulfur dioxide, and particulate matter—on the degradation and performance of capture media.

Solvent-Based and Sorbent Capture Technologies

Chemical Absorption Processes

• Design amine-based solvent systems, focusing on the chemistry of solvent regeneration, energy penalty reduction, and the management of heat-stable salts.
• Apply advanced concepts in solvent kinetics to optimize absorber tower dimensions and liquid-to-gas ratios for different capture requirements.

Solid Sorbents and Adsorption Cycles

• Master Temperature Swing Adsorption (TSA) and Pressure Swing Adsorption (PSA) processes for CO2 removal from dilute gas streams.
• Evaluate the physical and chemical characteristics of Metal-Organic Frameworks (MOFs), zeolites, and activated carbons regarding surface area, pore structure, and CO2 adsorption capacity.

Membrane and Cryogenic Separation Methods

Membrane Separation Science

• Analyze transport mechanisms in gas separation membranes, such as solution-diffusion, molecular sieving, and facilitated transport.
• Assess membrane modules and material configurations, including hollow fiber and flat sheet geometries, to maximize permeability and selectivity.

Cryogenic and Distillation Techniques

• Apply cryogenic separation methods for high-pressure industrial streams, focusing on phase separation and the control of CO2 solid-phase formation.
• Utilize multi-stage distillation cycles to purify CO2 to the high concentrations required for downstream transportation and storage specifications.

System Integration and Infrastructure

Compression and Transportation

• Engineer multi-stage compression systems to reach supercritical conditions, ensuring CO2 is in a dense phase for efficient pipeline transport.
• Understand fluid dynamics, material selection, and corrosion mitigation strategies for carbon dioxide pipelines, accounting for transient flow conditions and potential leakage detection.

Geological Storage and Utilization

• Examine the mechanics of CO2 sequestration in geological formations, including depleted oil and gas reservoirs, deep saline aquifers, and unmineable coal seams.
• Analyze trapping mechanisms, such as structural, residual, solubility, and mineral trapping, to ensure long-term containment integrity.
• Explore Carbon Capture and Utilization (CCU) pathways, including mineralization into building materials and chemical conversion of CO2 into synthetic fuels and industrial feedstock.

Economic and Life-Cycle Assessment

Cost Modeling and Techno-Economic Analysis (TEA)

• Construct comprehensive cost models for carbon capture projects, identifying capital expenditures (CAPEX) for equipment and operational expenditures (OPEX) including energy inputs and solvent replacement costs.
• Determine the "cost of CO2 avoided" as a key performance indicator to evaluate the economic feasibility of different technological configurations.

Life Cycle Analysis (LCA) Methodology

• Quantify the net carbon balance of a capture system by accounting for upstream emissions, energy penalty footprints, and long-term storage leakage rates.
• Master the ISO standards and reporting metrics required to demonstrate the environmental efficacy of carbon capture and storage projects.
