:1672-7207(2012)04-1211-06 Factors effecting mass transfer rates for air stripping of ammonia in multi-face-ball packed tower from ammonia-nitrogen wastewater WANG Hai-tao, ZHOU Kang-gen, PENG Jia-le, HU... flow rate on mass transfer rate of ammonia were investigated. The results show that under the best conditions of stripping and absorption processes, the ammonia stripping mass transfer coefficient KL......
baffle heat exchanger. The results show that the shell side heat transfer coefficient ho and pressure drop △po both increase while the comprehensive index ho/△po decreases with the increase of the mass flow rate of all schemes. And the shell side heat transfer coefficient, pressure drop and the comprehensive index ho/△po decrease with the increase of the baffle incline angle at a certain mass flow......
