I’m not sure whether the poster is looking for information on design or on practical manufacturing procedures! In the purification of maleic anhydride, it is important to avoid overheating, and attention must also be paid to controlling the temperature of the distillate, especially during the stages of removing the initial and final fractions ； When dehydrating, pay attention to controlling the dehydration stage – it is necessary to ensure proper acid levels in order to maintain the yield, while also avoiding an excessively long dehydration stage that could lead to backflow of acid. Since I don’t know what the original poster needs, it’s difficult to reply
