• The way of the methanol evaporation in the reboiler process is a traditional process. Almost all of the plants used this evaporation method before KaiMao has made research and promotion of multi - functional evaporator. There are almost 1000 formaldehyde plants with reboiler process in China.
• The process requires two devices, the reboiler and evaporator, to make methanol evaporation.
• Steam is used in the process for heating, which has derived from the oxidation reactor.
• This process is the most common process, and its biggest advantage is the less investment.
