Abstract
A Snyder-type distilling column having improved floating ball vapor valves. When used in a standard Snyder-type column, the valve comprises a spherical upper portion and a downwardly extending guide stem. When used in a microcolumn, the upper portion is mushroom shaped with a downwardly extending guide stem. The lower surface of either upper portion forms the valve face and includes multiple indentations therein. When a ball valve is closed, the indentations form by-pass passages to permit draining of condensed liquids therethrough thereby preventing flooding of the column. The indentations also permit the passage of vapors through the ball valve indentations thereby preventing sticking which can occur with a tight fitting ball valve and cause rotation of the ball valve during use which also assists in preventing sticking.
