Managing SAF production
The aviation industry faces a pressing need to decarbonise, with Sustainable Aviation Fuel (SAF) emerging as a key solution. However, SAF production presents significant challenges, including optimising complex catalytic processes and ensuring consistent product quality. This is where real-time, monitoring with a technology such as the Daily Thermetrics CatTracker becomes indispensable, according to the company.
The challenge of SAF production
SAF production typically involves upgrading existing refinery infrastructure to process renewable feedstocks like used cooking oil, agricultural residues, and municipal solid waste. This often entails integrating a variety of new catalytic processes, such as hydroprocessing and isomerisation, into existing refinery operations.
These processes are intricate, with numerous variables impacting catalyst performance and product quality. These variables include:
Feedstock variability: Renewable feedstocks can exhibit significant variations in composition, impacting catalyst activity and selectivity.
Catalyst deactivation: Catalysts gradually lose activity owing to coking, poisoning, and sintering, necessitating adjustments to operating conditions.
Product specifications: Stringent quality standards for SAF, including carbon content, energy density, and freezing point, must be consistently met.
The role of the Daily Thermetrics CatTracker
The Daily Thermetrics CatTracker provides real-time, in-situ monitoring of catalyst performance within refinery reactors. It employs embedded temperature sensors to measure precise temperature profiles along the catalyst bed.
How this technology is critical for SAF production:
Early detection of catalyst deactivation: By continuously monitoring temperature profiles, CatTracker Technology can detect subtle changes indicating catalyst deactivation, such as:
Hotspots: Localised temperature increases owing to decreased catalyst activity, potentially leading to reactor damage or runaway reactions.
Temperature gradients: Changes in the temperature profile along the catalyst bed, signaling variations in catalyst activity or flow distribution.
Early detection helps flexibility
Early detection allows for proactive adjustments to operating conditions, such as increasing feed flow rates or implementing regeneration procedures, maximising catalyst lifetime and minimising downtime.
Optimisation of operating conditions:
CatTracker data provides valuable insights into the impact of operating variables on catalyst performance, enabling real-time optimisation of:
Feedstock quality: By monitoring catalyst response to variations in feedstock composition, refineries can adjust processing parameters to maintain optimal performance.
Reactor temperature: Precise temperature control is crucial for maximising product yield and minimising side reactions. CatTracker data allows for fine-tuning temperature profiles to match desired product specifications.
Space velocity: CatTracker helps determine the optimal flow rate of feedstock through the reactor, ensuring efficient use of catalyst capacity.
Enhanced product quality control: By correlating CatTracker data with product quality analysis, refineries can establish robust relationships between catalyst performance and product specifications.
This enables:
Predictive maintenance: By anticipating potential issues with product quality, refineries can take corrective actions before they impact downstream operations.
Reduced off-spec production: Minimising the production of off-specification SAF reduces waste, improves operational efficiency, and lowers production costs.
Improved process understanding:
CatTracker data provides a wealth of information about the complex interactions within the reactor, enhancing process understanding and enabling:
Catalyst development: By analysing CatTracker data from various catalyst formulations, researchers can gain insights into catalyst behavior and develop more efficient and durable materials.
Process scale-up: CatTracker data collected during pilot plant studies can be used to optimise and de-risk the scale-up of SAF production processes to the required commercial scale.
Benefits of the technology
Increased profitability: By optimising catalyst performance, maximising product yield, and minimising downtime, CatTracker contributes to significant cost savings and improved profitability.
Reduced environmental impact: By optimising processes and minimising waste, CatTracker helps reduce the environmental footprint of SAF production.
Enhanced safety: By detecting potential hotspots and preventing runaway reactions, CatTracker improves process safety and minimises the risk of accidents.
Improved sustainability: By enabling the production of high-quality SAF from renewable feedstocks, CatTracker plays a crucial role in the transition to a more sustainable aviation industry.
