Company/Alliance: ELCOGAS, S.A
Location: Puertollano, Spain
Feedstock: Coal and pet-coke
Size: 14 MW of 335 MW plant; 100 tons/day
Capture Technology: Pre-combustion IGCC (90% capture)
CO2 Fate: Recycled back to the IGCC process
Timing: Construction permit (December 2008); Commissioning (May-October 2010); First CO2 captured (September 2010); End of characterisation tests (June 2011)
The objectives of the project are to: 1) Demonstrate at industrial scale the technical viability of precombustion carbon capture technology in a IGCC power plant, and 2) Obtain economic data about CO2 capture cost representative enough to scale it to full size.
The budget of the project (engineering, procurement, construction and commissioning) has reached €13.4 Million. The Spanish Ministry of Science and Innovation together with the Regional Government (JCCM) subsidized the project with €7 Million.
ELCOGAS offers both the Puertollano IGCC and the pilot plant for CO2 capture and H2 production as technical platforms to develop of process, equipment, components, or even pre-engineering of new plants with CCS and zero emissions.
The 14 MW pilot plant for CO2 capture and H2 coproduction is integrated in the Puertollano IGCC Plant, and treats 3,600 Nm3/h of syngas, equivalent to 2% of the total syngas generated in the IGCC power plant. The feeding gas can be either sweet (design conditions) or sour. The process is composed by three units: CO to CO2 conversion unit (using water gas shift technology), CO2 and H2 separation unit (using chemical absorption technology), and H2 purification unit (PSA). The pilot captures 100 tons per day of CO2 using the pre-combustion technology, being the capture rate higher than 90%. The pilot also produces 2 tons per day of 99.99% purity hydrogen.
