Abstract: A catalytic process for preparing chlorine from hydrogen chloride, which includes recycle of process streams with reduced accumulation of inert gases in the system is provided. The process includes a step wherein a compressed liquid stream comprising chlorine, carbon dioxide and oxygen is recycled into a column countercurrent to the ascending gas phase and feeding part of the chlorine-rich liquid phase leaving the bottom of the column back into the top of the column. Carbon dioxide present in the ascending gas stream is dissolved out of the gas stream and can later be separated from chlorine without problems by distillation.

Abstract: The invention relates to a method of controlling a hydrogenation of a starting material in a hydrogenation reactor, in which the amount of hydrogen reacted in the hydrogenation is firstly determined, the ratio of the amount of hydrogen reacted to the amount of starting material fed in is then derived, this ratio is compared with a prescribed value and, finally, at least one process parameter is altered if the ratio of the amount of hydrogen reacted to the amount of starting material fed in deviates by a prescribed amount from the prescribed value.

Abstract: A fluid reservoir assembly having a pan defining a drain opening and a plug disposed therein is disclosed. The pan includes a pair of ramps disposed on an inner surface thereof adjacent the drain opening. The plug includes a pair of wings in engagement with the ramps. The ramps increase in height relative to the inner surface of the pan along a first direction of rotation about the central axis. The plug is drawn into sealing engagement with an outer surface of the pan by rotating the plug in the first direction of rotation about the central axis thereby moving the wings up the ramps. The pan includes at least one stop to prevent over-rotation of the plug. The ramps define a recess to secure the wings in a closed position.
