Can the nitrogen used for pressurizing the coal powder lockhopper be recycled?

The nitrogen used for pressurizing the lock cylinder is contaminated with dust and moisture, and therefore cannot be fed into the nitrogen pipeline system. After step-by-step pressure release, it can only be used at low pressures and is thus of no use.
