We address the propagation and kinetic roughening of a liquid-gas interface moving through a disordered medium under the influence of capillary forces. The system is described by a phase-field model with conserved dynamics, and spatial disorder is introduced through a quenched random field. Liquid conservation leads to slowing down of the average interface position H and imposes an intrinsic correlation length proportional to H^1/2 on the spatial fluctuations of the interface.
