Abstract
An apparatus safely fills and empties a pressurized vessel charged with flammable and/or reactive gas. The apparatus features an upper flap combination, an intermediate lock vessel having a flushing apparatus, and a lower flap combination. The present invention also relates to a pressurized reactor which is charged with flammable and/or reactive gas and is equipped with a filling lock apparatus and an emptying lock apparatus for the simultaneous preparation of tetrachlorosilane, trichlorosilane and hydrogen. In addition, the present invention relates to a special process for filling and emptying such a reactor.
