A study on the PP hollow fiber membrane contactor and its performance for removing ammonia from wastewater or mixed gas: II. Ammonia removal from mixed gas

摘要

In this paper, we briefly discussed the utilization of the PP HFM contactor for removal of gaseous ammonia directly form mixed gas in ammonia manufacture in order to find an economic way to substitute conventional soft-water washing absorption technology. The Hollow Fiber Membrane (HFM) contactor has very high elimination (99.9/100) under optimum operation conditions.
