Abstract

The impure fluid is injected into a constant flow of the other fluid in timed, measured doses, the mixt. passed through a column which adsorbs impurities and the dosed batches, now purified diverted for collection at the column outlet, the undosed fluid with impurities being diverted to a separator for recycling, the outlet diverters are actuated by a programmed controller synchronised with the inlet dosing device. Produces gas mixts. for thermal decomposition to mfr. ultra-pure metals such as Si for electronic components.
