4A molecular sieves are used to remove water from xylene; in industry, is gas-phase dehydration or liquid-phase dehydration the better option?
It is recommended to use liquid-phase dehydration; if the moisture content in the medium is too high, it is advisable to remove some of the water first using other methods before applying molecular sieve dehydration. 1. Xylene has a relatively high boiling point, so gas-phase dehydration requires high energy consumption. 2. Although molecular sieves maintain good adsorption capacity at higher temperatures, they certainly cannot function properly at extremely high temperatures
