Abstract
Abstract A novel procedure is provided for conducting electrolyte to, from and through an electrolytic cell. This procedure depends on maintaining the cell in a fully flooded state and using the natural pumping action due to rising entrained and/or occluded gaseous products of electrolysis to aid the passage of the electrolyte through the cell at a velocity sufficient to prevent such gaseous products of electrolysis from separating into a free gaseous phase within the cell.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
A method for conducting an electrolyte through an enclosed electrolytic cell including an electrolytic zone and a plurality of nonelectrolytic zones, the method comprising: feeding electrolyte through the electrolytic cell while maintaining said cell in a flooded condition and substantially full of electrolyte; conducting the electrolyte through the cell, the electrolyte being abetted in its passage through the cell by virtue of natural pumping action due to rising entrained and/or occluded gaseous products of electrolysis; withdrawing effluent liquor including entrained and/or occluded gaseous products of electrolysis from the cell; separating the gaseous products from the effluent liquor; and refeeding liquor to the electrolysis zone.
Claim 2
Dependent Claim
23 words
The method as set forth in claim 1 including the step of first feeding the electrolyte downwardly in one of the nonelectrolytic zones.
Claim 3
Dependent Claim
46 words
The method as set forth in claim 1 wherein the electrolyte in passing through the cell is moving upwardly at a speed of between about 2 and about 100 feet per minute, abetted by the upward movement of entrained and/or occluded gaseous products of the electrolysis.
Claim 4
Dependent Claim
45 words
The method as set forth in claim 1 wherein the electrolyte in passing through the cell is moving upwardly at a speed of about 2 to about 50 feet per minute, abetted by the upward movement of entrained and/or occluded gaseous products of the electrolysis.
Claim 5
Dependent Claim
19 words
The method as set forth in claim 1 including the step of continuously adding fresh electrolyte to the system.
Claim 6
Dependent Claim
44 words
The method as set forth in claim 1 wherein the means allowing the effluent liquor to flow out of said enclosed cell is a riser, and wherein the product is flowing upwardly and outwardly at a velocity of 2 to 100 feet per second.
