θ环填料塔中单乙醇胺吸收CO2传质性能研究
Mass Transfer Performance in a θ-ring Packed Tower for CO2 Absorption Process Using Monoethanolamine (MEA)
摘要
Abstract
The mass transfer coefficient (KGav) and the removal efficiency of carbon dioxide for aqueous MEA-based absorption process were investigated in a packed absorber filled with θ-ring stainless steel packing. The experiment results showed that KGav decreased with the increase of CO2 lean-loading, and increased with the rise of MEA concentration and liquid flow rate. In addition, an increase in feed temperature from 30 to 50 ℃ led to an increase in KGav.关键词
