文摘
- •
Liquid film mass transfer coefficient is most sensitive to the carbamate reaction.
- •
Carbamate reaction rate follows same trend as unhindered amines.
- •
2PE forms a more stable carbamate than AMP.
- •
Bicarbonate reaction rate is ten times faster than for an analogous tertiary amine.
- •
The PFO assumption applies at low temperature, lean loading conditions.
