[0014] The present invention will be further illustrated by the following examples, the purpose of which is to better understand the content of the present invention.
[0015] A decarburization solvent contains N-methyldiethanolamine, and also includes a defoamer and an activator, wherein the content of the N-methyldiethanolamine in the decarburization solvent is 80-90wt%, and the decarburization The content of the foaming agent in the decarburization solvent is 0.1 to 0.5 wt%, and the content of the activator in the decarburization solvent is 10 to 20 wt%. In addition, the activator may be diethanolamine, monoethanolamine, sterically hindered amine, piperazine, or a mixture of two or more. The defoamer is dimethyl silicone oil.
[0016] The preparation of the above-mentioned decarburization solvent requires the following steps: firstly, N-methyldiethanolamine with a content of 80-90wt% in the decarburization solvent is added to the reactor, and then, the decarburization solvent i...
