Embodiment Construction
[0049] A processing technology of mixed amines, comprising the following steps:
[0050] a. Reduce the pressure of the mixture containing methylamine and methyldiethanolamine to 1-1.5MPa through the first pressure reducing valve, and pass it into the bottom of the deamination tower. The temperature of the bottom kettle of the deamination tower is controlled at 135-145°C. The methylamine in the vaporization rises to the top of the deamination tower and enters the condenser to be liquefied into liquid methylamine for recovery, and there is a mixture residual liquid containing N-methyldiethanolamine at the bottom of the tower;
[0051] B, the mixture residue containing N-methyldiethanolamine enters the flash tower through the second pressure reducing valve, and the mixture residue of N-methyldiethanolamine is distilled and separated into methylamine and N-methyldiethanolamine crude product;
[0052] C, the methylamine separated by N-methyldiethanolamine crude product in the flash...
