Dimethyl ether gas cooler

1. First, to answer your first question, the gases cooled in the gas cooler include CO, CO2, MEOH, DME, CH4, N2, etc. 2. They are mostly cooled in gas coolers. 3. Increasing the amount of water circulating in the gas cooler does not necessarily increase the volume of gas that is cooled, as it also depends on the diameter of the pipes, the flow rate, and the temperature of the circulating water.

The gas cooled in the gas cooler is mainly DME; as for CO, CO2, MEOH, CH4, N2, etc., it is difficult to condense them, and they are vented as non-condensable gases in the subsequent stage.

MEOH can be condensed; otherwise, how can the methanol tower separate methanol from water? CH4, N2, CO, and CO2 cannot be condensed in the gas cooler.

I can teach liquefaction at most. It can’t be called condensation

The distillation in the methanol tower relies on tray separation; the condenser at the top serves only to cool the methanol

Looking back at this old post now, my reply at that time was indeed not thorough. 1. First of all, the question posed by the original poster is not precise: All media that pass through a cooler can be cooled; it is impossible for only certain media to be cooled while others remain uncooled. And at that time, I took it for granted that “cooling” meant “condensation”. 2. My reply was intended only for the person above me; since I didn’t use the “reply” button at that time, it was inevitable that it was considered a reply to the original poster. 3. Methanol has a higher boiling point than dimethyl ether; since dimethyl ether can be condensed, methanol can certainly also be condensed. 4. Personally, I believe that the scope of \"liquefaction\" is broader than that of \"condensation\"; in other words, condensation is just one form of liquefaction. 5. Is the condensation of methanol related to the ability of the methanol tower to separate methanol from water? What’s the relationship? :L, I don’t even know what I was thinking at that time. Shameful!
