What is the temperature of dichloroethane vapor at around 140 degrees Celsius after being condensed using circulating water? ?

For dichloroethane vapor at around 140 degrees Celsius, after being condensed using circulating water to about 40 degrees Celsius, should secondary condensation be used to condense the liquid that has been formed, or should it be applied to the non-condensable gases coming out of the condenser? Why?
To what temperature does dichloroethane need to be cooled? If it’s 40 degrees, then continue cooling the non-condensable gas
Dichloroethane is volatile with a flash point of 13°C; therefore, it is advisable to cool it to several degrees. If stage 1 is cooled using circulating water to 40 degrees Celsius, can the liquid coming out of stage 1, along with the non-condensable gases from that stage, be fed into stage 2 for condensation? ?
Generally, the liquid is simply sent to the secondary cooling stage; if the concentration of dichloroethane in the non-condensable gases is high, those gases can be cooled separately
Sir, as shown in the picture, is this design reasonable? ?
Is it possible to seal the non-condensable gas outlet of the primary condenser, so that the final outlet for non-condensable gas is only at the outlet of the secondary condenser? ? In this way, the dichloroethane content in the non-condensable gas will be much lower
Non-condensable gas refers to either undecompressed dichloromethane or other gases that cannot be liquefied. Can the non-condensable gas shown in the diagram enter the secondary condenser?
Can the saturated vapor of dichloroethane, which is the main component in the non-condensable gases, along with some common non-condensable gases such as air, and a small amount of hydrogen chloride, enter the secondary condenser?
