Embodiment Construction
[0025] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the scope of protection required by the present invention.
[0026] According to the method for recovering methanol from tail gas washing water in the low-temperature methanol washing process provided by the invention, the following flow process is adopted:
[0027] Such as figure 1 As shown, in the low-temperature methanol washing tail gas scrubbing, the desalted water enters the tail gas scrubber 2 to absorb the methanol and CO in the tail gas 2 and other acid gases, forming a dilute methanol solution, because CO 2 Soluble in it, so the washing water is acidic, with a pH value of about 5.5. After the washing water is pressurized by the pump 5, it i...
