Study on the process of PVDF membrane condensation treatment of ammonia containing humid gas
This study investigates the process of treating ammonia-laden moist gas using the membrane condensation(MC)method.Based on a self-constructed laboratory-scale apparatus,different pore sizes of commercially available polyvinylidene fluoride(PVDF)membranes were selected to examine the effects of inlet gas pollutant concentration,inlet gas flow,inlet gas temperature,temperature difference across the membrane surface(ΔT),and membrane pore size on water recovery performance and the NH3-N content in the condensate.The results indicate that the feed gas flow rate of 1.0 L/min,pollutant concentration of 400 mg/L,feed temperature of 50 ℃,and ΔT of 20 ℃ can achieve higher water recovery performance with condensate containing lower levels of pollutants.
