introduction
All GL reactors need to be vented to alow air to be displaced/replaced when oil/bio is added to or removed from the vessel.
It is important that the vent does not have a valve on it as it must stay open at all times.
Vent layout
The vent on a GL is normally on the vapor line (highlighted in red) after the condenser, this way any methanol fumes that are released during the reaction,
or in the de-meth stage, will get condenced off and collected in the methanol collection vessel.
Concequences
Negative pressure
If the vent becomes blocked it can produce a build up of possative or negative pressure.
This can have sevear effects on the reactor it's self.
Negative pressure can and will cause the reactor to implode like in these pictures.
Posative pressure
The most likely way we could produce possative pressure in a GL is by pumping oil into it with a closed vent, allthough in most cases it is unlikely the pump will produce enough presure to cause a problem.
However if a reactor full of cold oil was heated with a closed vent this could build a suprising amount of pressure.
