Is it effective to use water spray to deal with a small amount of non-condensable dichloroethane in the condenser?

I’m curious about how diethyl ether non-condensable gas is generated – diethyl ether is immiscible with water, and it’s also difficult to remove water from diethyl ether during recovery. Can’t we just use a condenser directly? Use a single-shell four-stage or multi-stage condenser. Spraying with cold dichloroethane can be considered.
It’s similar to stripping, where steam is used to convert dichloroethane into vapor and carry it away; the non-condensable gas that results after two stages of condensation has a temperature of around 10 degrees Celsius. This gas wants to be recovered again, so I’m thinking of using water spray to reduce waste gas emissions. I wonder if that’s possible?
It’s not good; membrane separation technology can be used
