Abstract
The present invention relates to a method of increasing the concentration of dilute brine in NaCl electrolysis plants using the membrane process, wherein the NaCl required is stored in a mass flow silo with supernatant liquid and is fed continuously from there to the quick dissolver.
Claims6
Method of increasing the concentration of dilute brine in NaCl electrolysis plants using the membrane process, wherein the NaCl required is stored in a mass flow silo as solid crystals beneath the surface of a liquid and is conveyed as a flow of crystals to a quick dissolver.
A method of increasing the concentration of dilute brine in NaCl electrolysis plants using the membrane process, wherein the required NaCl is stored in a mass flow silo as solid crystals beneath the surface of a liquid, and is conveyed from said mass flow silo directly into a dilute brine stream as a flow of crystals.
