Latest Patents

**Adjustable Circumference Fractionation Tray and Method of Installation.** This invention describes a fractionation tray with slidable decking plates positioned between and alongside parallel downcomers. Sections of the plates between downcomers can extend toward the tray’s edge, allowing the tray’s shape to adapt to the column’s interior. The patent also describes an installation method in which an upper tray is supported only by the tray below it.

**Splice Support Construction of Multiple Downcomer Fractionation Tray.** This design uses an antipenetration pan to intercept liquid falling from the downcomer of an upper tray. Brackets attached to the tray decking and a horizontal deck brace support the pan above the lower tray surface. By locating the brace at a joint between adjacent deck plates, the construction combines pan support and tray-splice support in a simple, low-cost design intended for easy installation.
