Work package title: Knowledge-sharing, communication and dissemination
Start month: 1 (October 2017)
End month: 60 (September 2022)

Objectives:

• To share relevant knowledge regarding experience and policy issues among the partners
• To promote results to be duplicated in other industries and countries, and communicate why such duplication makes the project relevant for decarbonisation and creating/retaining employment across the economy, i.e. far beyond the project scope
• To facilitate communication within the consortium and with other relevant EU and Chinese networks

Description of work:

The purpose is to provide a virtual service centre for the project to ensure efficient and proper knowledge-sharing and handling of communication and dissemination activities. These activities will be planned and aligned with the Coordinator (and the Project Management, as described in Work Package 1). The intention is to facilitate and stimulate innovation, ensure trust and dedication, and increase the awareness of CCS and CO₂ capture techniques and their intended and potential suitability, as well as their relevance for overall deep decarbonisation of the global economy and for employment. Intentionally, these actions will pave the ground for the industrial uptake of CCS via retrofits in petroleum refineries, in the emission-intensive industrial sector, and in other energy-intensive industry.

Work package title: Integrated assessment for industrial scale-up
Start month: 13 (November 2018)
End month: 57 (June 2022)

Objectives:

• To develop a process model for prediction of full-scale CLC reactor system performance
• To carry out the required system level process simulation, including purification of unconverted fuel
  and unburnt CO and H₂
• To undertake techno-economic studies of an industrial CLC-CCS unit, including integration with CO₂ transport systems

Description of work:

CHEERS employs a multi-scale approach to modelling the CLC reactor system. The integrated assessment includes modelling the reactor from process unit level, through the plant, site and network levels based on the molecular and fluid phase modelling performed in WP3. The integrated assessment refers to the integration of the multi-scale process models and the economic models to perform a consistent techno-economic assessment.

Work package title: Process integration and system prototype design
Start month: 6 (March 2018)
End month: 27 (December 2019)

Objectives:

• To ensure optimal integration of the CLC reactor system with the heat recovery steam generation unit, cooler condenser, compression and purification, and to define the interface with external systems
• To carry out the Front End Engineering Design (FEED) and detail engineering for the fuel reactor
• To study the feasibility of possible options for flue gas treatment including DeSOx, DeNOx, and oxygen polishing
• To undertake the procurement of the fuel reactor and the remaining components of the system prototype

Description of work:

Process demonstration unit (PDU) takes into consideration all essential parts of an industrial unit in terms of design, construction and operation. In addition, it permits appropriate process integration studies for industrial scale. This work package takes into consideration the strategies proposed for development of the process from TRL5 to TRL7. The design of the system will consider all the necessary sections for TRL7 including CLC plant, feeding, boiler section and flue gas treatment. The flue gas treatment of the pilot plant will be based on the regional environmental regulation of demonstration units.

The flue gas treatment section for industrial units will be demonstrated separately. The technologies employed will be based on the available existing technologies (TRL9 or commercial). The required modifications of these systems will be carried out with the help of a subcontractor. The modifications will be demonstrated at a scale sufficient for industrial extrapolation, based on the existing know-how of the treatment technologies.

The process integration section will take into account the requirements of the refining site and the design specifications for critical sections, such as heat exchanger and boiler design, solid flow rate control, etc. A critical aspect of this work is to ensure the compatibility of different design sections between the fuel reactor and the rest of the unit, delivered by two separate engineering companies.

Work package title: Oxygen carriers and characterisation of fuel conversion phenomena
Start month: 1 (October 2017)
End month: 50 (November 2021)

Objectives:

• To ensure proper oxygen carriers for petcoke conversion by CLC technology
• To characterise oxygen carriers optimised for solid fuels with exceedingly high content of sulphur and
  metals
• To provide new knowledge on CLC via simulation of reactions and multi-flow phenomena
• To specify recipes for semi-industrial production of bespoke oxygen carriers (300 kg)

Description of work:

In CHEERS, the verification of oxygen carriers is an integrated activity which covers proven oxygen carriers, new local sources of supply (in Europe and China), and optimisation of fuel conversion. Oxygen carriers should be capable of sustaining the exceedingly high sulphur and metals contents associated with petcoke. Petcoke conversion is challenging due to low volatility, which makes petcoke less reactive than most solid fuels. The interaction between oxygen carriers and the petcoke gasification/burn-out is vital to the process efficacy. This interaction may also cause critical agglomeration and sulphur passivation.

Although some oxygen-carrier materials have already emerged, it is anticipated that bespoke oxygen carriers must be especially composed to ensure compatibility with petcoke. It is generally accepted that the lifetime of oxygen carriers is one of the most important characteristics. This generally means that candidate oxygen carriers should be inert to elements resulting from petcoke conversion. They must maintain a reasonably high reactivity and be insensitive to sulphur and metal-ions. Some oxygen-carrier materials even remove metal-ions, thus offering in-situ cleaning of combustibles. If these features can be combined, they may reduce process losses and cut costs associated with corrosion and cleaning. An inherent prerequisite is that absorbed metal-ions are prevented from clogging on the bed material. Testing of selected materials will be conducted under relevant conditions.

Work package title: Development and design studies
Start month: 1 (October 2017)
End month: 12 (September 2018)

Objectives:

• To provide the pre-FEED for the complete 3MWth CLC-CCS system prototype aimed at
  demonstration
• To establish the basis of design for the whole study
• To develop a reactor model for the designing and scale-up of CLC reactors to industrial size
• To design a 3MWth CLC reactor system for demonstration (via TRL5, TRL6 to TRL7)
• To optimise the process via simulation

Description of work:

A pre-FEED consists in a conceptual design package including all necessary process information required for the engineering steps. FEED stands for Front-End Engineering Design. The work package provides the detail design of the chemical looping part of the demonstrator and all the data required for the engineering study (Work Package 4). A first step will be to establish a common basis of design assuming that the site location has been identified and known, and finally decided at project start-up.

The second step will be to develop a reactor model for the scale-up to 3MWth (compliant to TRL5,6,7) based on experimental data initially achieved at TRL4. Finally, the detail design of the chemical-looping reactors and the process study will be conducted in parallel to provide the pre-FEED of the demonstrator to Work Package 4.
