The value of vacuum dehydration is to remove water from the raw oil under vacuum conditions, not during the production process; after the liquid-phase reaction is completed, the methanol is recovered by heating, while the gas-phase reaction is to recycle the methanol at the same time. The specific process depends on which process<br>
