A signal device including a plurality of visually different flags in a mounting frame is secured to the top of a cubicle wall forming a part of a workstation, so that the status of the workstation user can be visually determined. The flags are normally in a generally horizontal position in the mounting frame, and may be in a recess in the top of the cubicle wall. A flag corresponding to the desired message is raised from the mounting frame, so that the flag is visible above the top of the cubicle wall.

The present invention relates to an improvement to a process for the production of methanol from synthesis gas containing carbon monoxide and hydrogen utilizing a three phase or liquid-phase reaction technology. The improvement to the process is the addition of relatively small amounts of water to the liquid-phase reactor thereby allowing for the use of a CO-rich synthesis gas for the production of methanol by effectuating in the same reactor the methanol synthesis and water-gas shift reactions. A portion of the unreacted synthesis gas stream from the liquid-phase reactor is separated into a hydrogen-rich component and a carbon monoxide-rich component. The hydrogen-rich component is combined with a portion of the unreacted synthesis gas stream from the liquid-phase reactor to form a gas-phase methanol reactor feed stream for producing methanol, and the carbon monoxide-rich component is combined with the unreacted effluent from the gas-phase methanol reactor to form a feed stream for combustion in a gas turbine.

The present invention is a process for the production of methanol from a syngas feed containing carbon monoxide, carbon dioxide and hydrogen. Basically, the process is the combination of two liquid phase methanol reactors into a staging process, such that each reactor is operated to favor a particular reaction mechanism. In the first reactor, the operation is controlled to favor the hydrogenation of carbon monoxide, and in the second reactor, the operation is controlled so as to favor the hydrogenation of carbon dioxide. This staging process results in substantial increases in methanol yield.
