The use of methanol recovery tower know-how and process

Different recycling tower use know-how, people generally believe that methanol recovery tower is mainly in the chemical industry, in fact, not so, in many industries in the recovery tower have played a great material recycling, because the material itself is mainly stainless steel 304 models to produce, and the structure can be customized according to the requirements of the industry, and the built-in aspects of the recovery tower will also have a certain shelf life All in all, the recycling tower is too widely used.

Also because of the simple operation of the structure, as long as it is according to the manual drawings to operate without problems, as long as in the normal operation of the situation, there will be no interruptions stop. In addition, in the methanol recovery tower operation to have reasonable guidance, do not use without the actual operation of the situation, so that not only the equipment itself has an impact on the other connected equipment also has a great stimulus, in the resources recovered will also produce the corresponding chemical reaction, not the same methanol recovery tower is a great difference in material, the internal structure of the change is more conducive to the play of the equipment itself The methanol recovery tower is made of different materials and has a large gap in terms of internal structure.



Methanol recovery tower waste gas out of the production line temperature is high, in 70 to 80 degrees, may contain a small amount of solid impurities, so first filter to remove impurities, and then into an absorption section, in this absorption section using a solvent concentration of fifteen to twenty percent of the mixed aqueous solution in an absorption section to absorb waste gas, absorption of the absorbent solution according to the material constant calculation, part sent to distillation recovery, the rest continue to cycle.


Due to the high concentration in the aqueous solution, the purification efficiency of the first absorption section will not be too high, out of the first absorption section of the gas to get preliminary purification, absorption efficiency can reach seventy to eighty percent, and then into the second absorption section. The concentration of the absorption solution in the second absorption section is very low and is closer to that of clear water, therefore, it can be further purified and discharged after meeting the emission requirements.
