There can be various reasons for continuity eqn divergence.

Could you give more information about your physics setup: What multiphase model are you using? Is the gas modeled as compressible? What BCs are you currently using? Are you solving this as steady state with MRF for the rotor-stator?

A few screenshots of the setup will be helpful showing the setup. 

In the cross section plot with the methane vf, where are the inlet, impeller and outlet? Also include a picture of the mesh on this plane.
