We are a team (two students actually) who are trying to develop a
3D Graphic System. The system is being built as a package on top of
a already excisting 2D Graphic System. Our problrm is that we cannot
find any Hidden Line Hidden Surface algorithms that don't demand acess
to the pixel-memory. What I wonder is: are there any algorithms for
hidden line hidden surface removal that uses primitives (in any graphic
system) AND not the pixel memory

Look in any of the standard text books. Newman and Sproull or Foley and Van Dam, for example. In fact, only the z-buffer algorithm "requires" the frame buffer. All other hidden line or hidden surface algorithms either produce output in a different format or have easy variants that do so.
