Gas management systems

The air and flue gas management system includes the various baffles, dampers, fans, dust collectors, scrubbers, and other FGD and emission control equipment, and the boiler flues and stack (chimney). 

Otherwise, these metals are difficult or nearly impossible to be formed. In this process, the sheet metal is placed in a heated die held closed by the press. The forming is then accomplished by gas pressure that forces the metal to slowly conform to the shape of the die. The press must have sufficient capacity to overcome the force of the gas pressure and maintain the force for hours while the process takes place. Superplastic forming presses must be thermally insulated and usually include the hot plates, temperature control, and gas management system for the process. 

Diffusion bonding is another process primarily used by the aircraft indu.stry to bond certain metals by using heat and pressure under controlled conditions. Hydraulic pres.ses are used to provide the bonding force with precise control over the pressing force, pressing velocity, and parallelism. As with superplastic forming, this process also usually involves thermal insulation, hot plates, temperature control, and a gas management system. 

When you think of installing a gas chromatograph, you need to consider the entire system in order to run the new chromatograph(s) to peak efficiency. This means thinking of all aspects of the installation. The information in this chapter will help you design your gas management system wisely and obtain efficient performance from one or many gas chromatographs in a laboratory.
