4.7 MEMBRANE ELECTROLYSIS

4.7.7 Operational and Maintenance Experience

The following summarizes the respondentís O&M experiences and provides operating labor information.

  • Two shops provided operating labor data. For these shops, the average number of annual operating hours per membrane electrolysis unit were: 200 hrs/yr (assumes 250 hrs/yr for each of the two units operated by PS 275). The following is a breakdown of the responses for skill requirements (based on data from PS 006, PS 052 and PS 275):
           Environmental Engineer:   0
           Process/Chemical Engineer:0
           Chemist:                  1
           Consultant:               0
           Plumber/Pipe Fitter:      0
           Electrician:              0
           Vendor:                   0
           Senior-Level Plater:      1
           Junior Level Plater:      0
           Trained Technician:       2
           Common Labor:             0
           Other:                    0
      
  • Reported O&M problems for this technology include: (1) occasional clogging of pipes (PS 052); short life span of membrane and anodes (PS 006); and (3) very difficult to clean out collected residuals from unit.
  • Ionsep reported the following expected life spans of system components: membrane >12 mth, anode 12 to 36 mth, and cathode >60 mth.
