Title:
AMINE RECOVERY METHOD, AMINE SEPARATION APPARATUS AND ACID GAS SEPARATION AND RECOVERY APPARATUS
Document Type and Number:
Japanese Patent JP2014100623
Kind Code:
A
Abstract:
To provide an amine recovery method capable of recovering a reusable amine component with low energy, an acid gas separation and recovery apparatus and an amine separation apparatus.
An amine separation apparatus comprises a first separation membrane and a second separation membrane. The first separation membrane is formed with a first pore size separation material corresponding to the molecular size of a deteriorated amine and separates the deteriorated amine from an amine solution. The second separation membrane is formed with a second pore size separation material and separates a reusable amine selectively from the amine solution passed through the first separation membrane. A second pore size is smaller than a first pore size.
