<strong>SGC</strong> Rapport 2013:277<br />
In addition to the chemical energy change, the overall electricity efficiency has<br />
been determ<strong>in</strong>ed us<strong>in</strong>g the def<strong>in</strong>ition <strong>in</strong> section 3.4. Based on these assumptions,<br />
the case with the water scrubber comes out at 60.7% and the am<strong>in</strong>e case to<br />
60.9%, the <strong>in</strong>puts and outputs are summarized <strong>in</strong> Table 11.<br />

6.3.2 Case 2 – 100 MWth<br />
The second case has been centered on the MILENA <strong>in</strong>direct gasifier and us<strong>in</strong>g the<br />
OLGA gas clean-up. In this case, CO2 separation has been considered both before<br />
and after the methanation. Some gas compositions from the system may be<br />
viewed <strong>in</strong> Table 12.<br />
