The Octavius project, funded by the EU under FP7, aims to optimize CO2 capture technologies for utility-scale implementation over a 60-month period starting March 2012, with a total budget of €13.56 million. It includes three main sub-projects focusing on modeling and support, demonstration of operational aspects, and the DMXTM process for CO2 capture, with extensive pilot plant tests conducted across various locations. The project has shown promising results in terms of CO2 capture efficiency and cost reduction, while also addressing challenges related to solvent degradation and emissions control.

5. OCTAVIUS – Project Overview
 Two main technical Sub-Projects
 SP2 dedicated to demonstration of operability and flexibility aspects
of first generation processes to be used for first full scale demo plant
(e.g. ROAD and Porto Tolle Projects)
 SP3 dedicated to the demonstration of the DMXTM process
 SP2 and SP3 are independent
Subprojects

features to show the potential of reduced energy requirement
and reduced costs for full scale plants
 3 main WPs
 WP11: Developing models and simulation tools
 WP12: Basic emission control studies

 WP13: Performance evaluation and basis for benchmarking
 including comparison first and second generation processes,
comparison for optimal integration

for Dynamics) and are currently being compared.
 Models for MEA degradation have been developed based on
Laboratory data – now to be tuned to pilot plant results.

methods defined towards
development of Standard

(SOPs)
 Methodology for
benchmarking defined.

9. SP3: Demonstration of the DMXTM process
 Objectives
 Demonstrate the DMXTM process on the ENEL pilot plant in Brindisi
 Study application of this process to coal and NGCC plants
First Evaluation (2011):
- < 2.5 GJ/tCO2
- 25 % reduction on CO2 capture cost
- validate within SP3 OCTAVIUS

11. SP3 Current Status
 Phase 1 of Sub-Project SP3 Completed
 Experimentation on Minipilots at ENEL
and IFPEN
 Decantation studies
 First techno-economic study on a coal case
 FEED study and cost estimation for retrofit
 Potential of DMX Process confirmed
compared to MEA 30 wt% Process
 Less degradation and corrosion
 No decantation issues
 No toxicology or emissions issues
 More than 20% reduction in terms of Energy Penalty
 More than 20 % reduction in terms of CO2 avoided Cost

12. SP3 Current Status
 Go/NoGo decision meeting held on 11 December 2014
 All technical criteria reached: we need to demonstrate the process on an
industrial pilot plant to confirm its potential at scale.
 After cost estimation, it appears a large cost increase is required for the
revamp of the Brindisi pilot plant.
