Total power station output = 2000MW electrical. .Efficiency: around 90% of CO2 removed from flue gas .Project budget: more than £20 million .Public funding: more than £6 million from DECC, TSB and Northern Way" Therefore approximately 111 tonnes of CO2 / day is emitted by generating 5MWe, of which 90% can be collected (100 tonnes of CO2 / day) Now look at page 11 the presentation below http://pennwell.websds.net/201...ows/T2S7O2-slides.pdf This document gives the typical solvent regeneration energy for Monoethanolamine (MEA), which is 3.6 to 3.9 GJ/tonne CO2 Therefore for the CCPilot100+ this will be approximately 375 GJ per day if 100 tonnes of CO2 is captured in a 24 hour period. The electrical energy generated during this period is 432 GJ (5MWe for 24 * 60 * 60 seconds) Therefore the MEA solvent regeneration energy expressed as a percentage of the electrical energy is around 86% I thought the carbon capture process was supposed to be more efficient than this? Have I got the calculation wrong? I presume much more efficient methods are in the pipeline. James Arathoon ------------------------- James Arathoon
