To achieve good liquid-vapor contact and at the same time better utilize the heat of reaction in a distillation column reactor a system is provided wherein a reaction tray and distillation tray are "coupled" by a continuous liquid level between the two. A reaction tray, containing the appropriate catalyst, is situated directly below a distillation tray. A vapor riser is provided through the reaction tray as a by-pass which carries the vapor from a lower distillation tray to a vapor distribution area underneath the "coupled" distillation tray. Liquid flows downward through a downcomer by-passing the "coupled" distillation tray, and onto and across the "coupled" reaction tray immersing the catalyst and rises upward, onto and across the "coupled" distillation tray where it is intimately contacted with the rising vapor effecting fractional distillation. Only that vapor produced by the reaction on the reaction tray rises through the catalyst minimizing movement and pressure drop while the heat produced contributes to the distillation. A sufficient vertical distance between the two "coupled" trays is provided to allow disengagement of any catalyst particles which might become entrained in the rising liquid.

A valve lock for valves wherein the valve stem is coupled to a valve actuator shaft and there is a spacing between the valve and valve actuator. A locking member is slidably receivable in the spacing and fixed against rotation so that a locking slot in the locking member engages a locking segment of the interconnected valve stem and valve actuator shaft. The locking member, in turn, can be releasably locked to prevent unauthorized or unintended use of the valve.
