Should all the fluid exiting the primary cooler in stage I of methanol distillation be sent to the secondary cooler?
Does the original poster have a better solution? If the temperature of the gas coming out of the first stage is low, it can be released directly. However, generally speaking, in order to ensure product quality, the temperature at this stage is kept above 40 degrees, which is why it is necessary to pass the gas through the second-stage condenser! This portion of liquid in the secondary condenser can be sent to the pre-condensation return tank or to the fusel oil tank. The condensed gas can be vented after passing through a water seal; once the liquid in the water seal reaches a certain concentration, it is then sent to the fusel oil tank
