Glanor® cell

There are two bipolar filter-press cell designs for manufacturing chlorine, the Dow cell and the Glanor cell. Both use finger-type electrodes, as opposed to flat plates. The Dow cells, developed over the past eighty years [76-79] are simple and rugged. They employ... 

There are two versions of the Glanor electrolyzer V-1144 containing 11 cells, each having an area of 35 m, and V-1161 containing 11 cells, having an area of 49 m per cell. The Glanor cells are currently used only by PPG Industries in the United States, Mexico, and Russia. 

The frequency of cutout activity was reduced by a factor of from 6 to 11 times for the new bipolar PPG-De Nora Glanor cells (25)...

Glanor A Chlor-Alkali process using a bipolar diaphragm cell. Developed by PPG Industries and Oronzio de Nora Impianti Elettrochimic in the early 1970s. 

PPG and DeNora jointly developed a bipolar filter-press diaphragm cell called the Glanor electrolyzer [32]. The central design feature is the bipolar electrode where one side acts as an anode and the other as a cathode. The electrode consists of a steel plate to which anode fingers are connected on one side and cathode fingers on the other. 

A unique feature of the cathode design is the extension of the cathode fingers from the back plate, which allows easy inspection of the cathode surfaces, and the adaptability to use synthetic separators with minor modifications. The anolyte compartment is connected to an independent brine feed tank by flanged connections and chlorine leaves from the top, through the brine feed tank and then to the chlorine header. Each electrolyzer is fitted with a level alarm, which monitors the level of all the cells in the unit. Figure 5.16 is an isometric cutaway of a Glanor V Type 1144 electrolyzer.

Glanor bipolar electrolyzers are a joint development of PPG Industries and Oronzio De Nora Impianti Elettrochimici S.p.A. The Glanor electrolyzer consists of several bipolar cells clamped between two end electrode assemblies by means of tie rods, thereby forming a filter press type electrolyzer (Fig. 35). The electrolyzer is equipped with DSA titanium anodes. Each electrolyzer normally consists of 11 or 12 cells. A lower number of cells can, however, be assembled in one electrolyzer. The Glanor electrolyzer was especially designed for large chlor-alkali plants.
