Using high resolution VLT spectra, we study the multi-component outflowsystems of two quasars exhibiting intrinsic Fe II absorption (QSO 2359-1241 andSDSS J0318-0600). From the extracted ionic column densities and usingphotoionization modeling we determine the gas density, total column density,and ionization parameter for several of the components. For each object thelargest column density component is also the densest, and all other componentshave densities of roughly 1/4 of that of the main component. We demonstratethat all the absorbers lie roughly at the same distance from the source.Further, we calculate the total kinetic luminosities and mass outflow rates ofall components and show that these quantities are dominated by the mainabsorption component.
