Chemical vapor trap and vacuum drying system including same |
摘要 |
A chemical vapor trap for selectively removing harmful corrosive contaminants, such as water and acetic acid vapors, from an evacuating vapor phase in a vacuum drying system is provided. The chemical vapor trap includes a condenser section effective to convert a high temperature incoming heated sample liquids and heated vapor phase into a liquid phase condensate and a relatively lower room temperature stripped vapor phase. Liquid condensate including water and acetic acid are trapped below a chemical blanket or sealing layer which prevents re-vaporization or boiling of removed corrosive volatile contaminants from the vapor phase entering the vacuum pumps, promoting improved pump performance and extend pump service life.
