ABSTRACT:
The separation process and apparatus is based on conducting the explosive gas or vapour through a mass transfer column which is charged with an absorbent and filled with an electrically conductive packing. The packing (2) of the mass transfer column (1) must be earthed and have such a dense lattice spacing that no electric charge sufficient for ignition can accumulate at any point in the packing. Under these conditions, a non-conductive electrostatically chargeable liquid may be used as absorption liquid.
