As the temperature changes so does the membrane performance. As a consequence the capacity and feed-air factor differ from the ones at nominal temperature (20ºC). Hereafter are the tables with correction factors for temperatures differing from 20ºC for the HiFluxx/Smartfluxx and Enoxy membrane modules. Table 1 Table 2 1) These numbers are indicative and may vary by +/- 0.1. Example Corrected Nitrogen Flow Calculation at 50ºC and 97% Corrected nitrogen flow: 15 m3/hr x 1.1 = 16.5 m3/hr Corrected Feed-Air Calculation at 50ºC and 97% Corrected feed-air flow: 52.5 m3/hr x 1.3 = 68.3 m3/hr Membrane Temperature Correction Factors HiFluxx SmartFluxx Temperature Nitrogen flow rate correction factor for SmartFluxx (SA) at various product concentrations1) 99.5% 99% 98% 97% 96% 95% 5°C (41°F) - - 0.90 0.90 0.90 0.90 10°C (50°F) - - 0.95 0.95 0.95 0.95 20°C (68°F) 1.00 1.00 1.00 1.00 1.00 1.00 30°C (86°F) 1.00 1.03 1.05 1.05 1.05 1.05 40°C (104°F) 1.00 1.05 1.10 1.10 1.10 1.10 50°C (122°F) 1.00 1.05 1.10 1.10 1.15 1.15 60°C (140°F) 1.10 1.15 1.20 1.20 1.25 1.20 Temperature Feed-Air consumption correction factor for SmartFluxx (SA) at various product concentrations1) 99.5% 99% 98% 97% 96% 95% 5°C (41°F) - - 0.90 0.90 0.90 0.90 10°C (50°F) - - 0.95 0.95 0.95 0.95 20°C (68°F) 1.00 1.00 1.00 1.00 1.00 1.00 30°C (86°F) 1.10 1.10 1.10 1.10 1.10 1.10 40°C (104°F) 1.25 1.20 1.15 1.15 1.10 1.10 50°C (122°F) 1.35 1.30 1.25 1.20 1.15 1.15 60°C (140°F) 1.60 1.60 1.55 1.55 1.50 1.50 Table 1 Table 2 1) These numbers are indicative and may vary by +/- 0.1.
