Mud gas separator is related to choke manifold, to remove the free gas in drilling dirt. It can be used for unbalanced drilling and also drilling mud that contain H2S gas. Gas-cut drilling water enters the dirt gas separator from your mud inlet, falls onto a series of specially-designed internal baffles alongside inner wall, collides up against the baffles, increases its exposed surface area, flows downwards and also forms the turbulence condition, so in respect of separate the gas from drilling water in mud gas separator.
