RESIN DEGASSING

Disclosed are processes and systems for degassing liquid resin. Resin is provided at a resin inlet and pumped into a first duct using a resin pump to achieve a first absolute pressure of at least 1.6 bar in the first duct; the resin pump and/or a flow control valve are configured to achieve a first...

Zusammenfassung:	Disclosed are processes and systems for degassing liquid resin. Resin is provided at a resin inlet and pumped into a first duct using a resin pump to achieve a first absolute pressure of at least 1.6 bar in the first duct; the resin pump and/or a flow control valve are configured to achieve a first pressure drop across the flow control valve of at least 1.5 bar; a second duct communicates the resin from the flow control valve to a storage tank; a gas evacuation system maintains a pressure in the storage tank below 100 mbar at least partly concurrently with pumping resin into the first duct.
