ICIFM-21SP Monopolar Electrolyzers. Id s EM-21 SP monopolar electrolyzer incorporates stamped electrodes that are 2 mm thick and of a relatively small (0.2 m ) size (50). The electrolyte compartments are created by molded gaskets between two of the electrode plates the electrode spacing is finite and is estabHshed by gasket thickness. The electrode frames are supported from rails and are compressed between one fixed and one floating end plate by tie rods. Inlet and outlet streams are handled by internal manifolds. A crosscut view of the electrolyzer is shown in Eigure 21. As of 1989, ICI had Hcensed 20 plants having an annual capacity of 468,250 t of NaOH. 

Referring again to Fig. 9.7.18, the salient features of this design are that in a pre-injection state, or standby mode, a stream of analyte flows in the SIC while reservoirs D and F are grounded (Fig. 9.7.18b). Voltage is then applied to reservoir B, sample is introduced to the electrophoretic manifold and spontaneously flows to reservoir D, while buffer flows down the separation channel to reservoir F. For injection, all reservoirs are left floating momentarily, and a small plug of sample... 

Offshore structures are relatively self-sufficient they provide electrical generators, water desalinators, sleeping facilities, communication stations, and modern amenities. Production platforms are connected by pipelines or floating storage units to onshore operations. Key process elements of oil and gas recovery include wellhead, production manifold, production separator, water injection pumps, gas compressors, glycol process to dry gas, oil and gas export metering, and main oil-line pumps. 

The actual operation of this machine is relatively simple. Reservoirs (1) contain the developing solvents, which are forced by carbon dioxide pressure into the glass manifold above the column to maintain a constant hydrostatic head. This is regulated by a float device (2) which controls the application of carbon dioxide pressure to the desired reservoir.
