Stakeholder input process

How will your project work with and respond to the community while staying compliant and adaptable.

Pathway-specific

How will your project meet pathway-specific process requirements.

Projects must describe and provide an engineering design diagram of the chemical reactor used to achieve pyrolysis.

The design diagram must include details of the dimensions of the reactor, the locations of material inflows/outflows, the positioning of sensors for the monitoring of temperature/pressure, details of any internal equipment such as agitators or heating/cooling coils and details of any external heat transfer equipment.

A sufficient number of viewpoints must be included in the engineering design diagram to show the positioning of all of the key components.

Any other process equipment essential to the safe and effective operation of the pyrolyzer not listed should be included and highlighted in the engineering design diagram.

Projects must describe and evidence the sensors used to quantify any loss of pyrolysis gasses during operation of the reactor to leakage.

This should include, at minimum, sensors to determine the outflow of pyrolysis gasses from the flue gas outlet, which can be used in conjunction with a suitable reactor model to determine the amount of pyrolysis gasses produced and to estimate any loss of these gasses by unmonitored and unintentional leakage to the environment.

The chemical reactor model used to characterize reactor performance and estimate pyrolysis gas losses should consider all physical and chemical mechanisms relevant to the operation of the chosen reactor type.

The chemical reactor model should incorporate a chemical kinetics model which is based on the latest scientific understanding for the chosen reactor configuration.

The model should be demonstrated to be validated using empirical data and should include a process mass balance accounting for the product yields.

Where high-quality mathematical reactor models aren't possible, it is permissible to deploy alternative approaches, such as continuous measurement of system pressure or regular leakage testing.

For continuous measurement of system pressure, projects must demonstrate that the pressure of the reactor vessel during project operations is consistently sub-atmospheric and measured using a calibrated sensor.

For regular leakage assessments, projects should conduct tests according to prevailing national/international standards, and/or by an accredited leakage testing authority, at least once every twelve months.

Projects must describe the selection of materials for each component of the reactor, including suitable justification of these choices from the perspectives of thermal and mechanical resilience.

For reactors operating at high pressures, considerations should be made relating to the operating pressure, vessel shape/size, positioning of material inlets/outlets, and positioning of sensors to ensure mechanical integrity of the reaction vessel.

Considerations should be made in compliance with a suitable local standard which provides regulations for the design and fabrication of pressure vessels, such as 2014/68/EU (the "Pressure Equipment Directive") or an appropriate regional equivalent standard in the region of project operation.

If no regional standard exists in the region of operation, Project Proponents must use the 2014/68/EU standard.

Projects must describe and evidence an appropriate reactor maintenance plan.

The maintenance plan should outline how the Project Proponent will ensure the structural integrity of the reactor vessel to mitigate against potential material loss events.

This includes suitable monitoring and mitigation for mechanical and thermal degradation events which may lead to the failure of the vessel and subsequent release of materials into the environment.

All maintenance plans should be in compliance with a suitable local standard which provides regulations for the maintenance of pressure vessels, such as 2014/68/EU or an appropriate regional equivalent standard in the region of project operation.
