What is the significance of controlling the temperature of the gas after it has been cooled by synthetic water?
Excessive outlet temperature； Within the alcohol fraction ； The separation effect is poor ； Resulting in reduced yield
If the temperature of the gas after cooling in the synthesis process is controlled too high, it will affect the condensation of methanol and water vapor in the gas. As a result, the amount of methanol that remains uncondensed in the syngas increases; this methanol not only raises the power consumption of the compressor but also inhibits the methanol synthesis reaction within the synthesis tower. However, it is also not necessary to keep the temperature of the gas after cooling it with water at too low a level. When the gas temperature drops below a certain threshold, the improvement in methanol condensation is not significant; therefore, striving for an excessively low cooling temperature is not economical.
