Importance of venting a processor

This page will soon be completed by Mark following an intensive and extensive wiki lesson.

Only if he was paying attention.

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 doesn't 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 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

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.
