We present analysis and photoionization modeling of the Chandra high resolution spectrum of Mrk 279 .
There is clear evidence of an absorbing outflow which is best fit by a two component model , one with a low ionization parameter and one with a higher ionization parameter .
The column density of the X-ray warm absorber , about \log N _ { H } = 20 , is the smallest known of all AGNs in which X-ray absorbing outflows are observed .
We find that the X-ray and UV/FUV absorbers are part of the same overall outflow .
There is some evidence of super-solar carbon , nitrogen , oxygen and iron in the Chandra spectrum of Mrk 279 .
While this is not a robust result in itself , Chandra data in combination with the UV data and the pressure equilibrium between two phases of the outflow , support the scenario of super-solar abundances .
This the first case where super-solar abundances are reported in the nucleus of a normal Seyfert galaxy .
The data suggest that the outflow originates from a compact region around the nuclear black hole and that it carries insignificant amount of mass and energy .
