ANICA is a project focused on developing a novel indirectly heated carbonate lopping process for lowering the energy penalty and CO2 avoidance costs for CO2 capture from lime and cement plants. It is funded through the ACT programme (Accelerating CCS Technologies, Horizon2020 Project No 294766). Financial contributions made from the German Federal Ministry of Economic Affairs and Energy, the Department for Business, Energy and Industrial Strategy of the United Kingdom and the Greek General Secretariat for Research and Technology.

The overall aim of the project is to develop concepts of the indirectly heated carbonate looping (IHCaL) process for CO2 capture from lime and cement plants. In the carbonator, the CO2 contained in a flue gas is absorbed by CaO, and the CaCO3 formed herby is regenerated in an indirectly heated calciner. The heat for calcination is produced by combustion of fuel with air in an external combustor and transferred to the calciner by means of heat pipes. The flue gas of the external combustor is directed to the carbonator.

The main innovation of the ANICA project is the use of an indirectly heated calciner for regeneration of the calcium looping sorbent (CaO) and its integration into lime production plants and cement production plants. This would allow for the recycling of CaO as raw material for lime and cement production. Additionally, novel concepts of heat exchange will be developed.

CERTH/CPERI activities in ANICA project include: i) Development of two novel concepts -the tail-end and the fully integrated solution- for integrating the IHCaL process into the existing lime plant of CaO Hellas in Thessaloniki, Greece. The concepts are developed and simulated in Aspen PlusTM, heat and mass balance equations are established and a detailed sensitivity analysis is performed, ii) Design, proof of concept and simulation by means of Finite Element Analysis (FEM) of a novel concept of a solid/solid heat exchanger (Concentric double L-VALVE) for the IHCaL reactor system, iii) Three-dimensional CFD simulation of the 300 kWth calciner reactor to find suitable design and operating conditions for an optimum CO2 production and heat exchange; an in-house version of the Energy Minimization Scheme and several custom-built functions of the reaction kinetics will be coupled with the Eulerian-Lagrangian DDPM approach to capture with a high level of accuracy the inter-related flow hydrodynamics and reaction kinetics. iv) Finally, CERTH acts as a National Consortium Leader (NCL), which is the interface between the project partners and the corresponding national funding agencies, i.e. the General Secretariat for Research and Technology (GSRT).
