Apparatus for aqueous solutions of pure sodium hydrosulfite

摘要

Apparatus and method are disclosed for continuously handling sodium hydrosulfite for use in textile dyeing including means for receiving the pure dry chemical in semi-bulk returnable containers, for dissolving the same in a caustic solution and for storing the resulting solution in low inventory automatic make-up tanks. The novel resulting solution is stabilized against decomposition and may be metered to specified locations in the textile mill.
