FM21-SP® cell

The process is nearing the end of a 3000 hour pilot trial at the Shawinigan laboratory of Hydro-Quebec in a commercial scale Electro Prod Cell, or an ICI FM21 SP cell, divided by a membrane. The pilot plant based on commercially available electrochemical cells has a design capacity of 100 t/year [132], Compounds examined on the laboratory scale using the Ce(IV) methane sulfonic acid process are summarized in Table 11. 

The recently introduced FM21 SP cell (Fig. 2.32) represents a general-purpose design which is a development from FM21 chlor-alkali cells (section 3.3 3).

The anodes and cathodes are assembled between two end plates, up to 60 anodes in the FM21-SP and up to 90 anodes in the larger FM-1500. A key feature of both designs is the elimination of any external piping to the individual cell compartments by the use of a simple but effective internal manifold arrangement. As shown in Fig. 5.30, the anode and cathode panels are designed to form feed and discharge channels when assembled.
