Gas monitoring

The horsepower output from a gas turbine is seldom limited by the position of the fuel-gas regulator, as I just described in the previous example. The limit is usually the exhaust temperature of the combustion or flue gases. The turbine s blades have a metallurgical temperature limit of 1100 to 1200°F (as designated by the manufacturer). The temperature of the exhaust combustion gases monitors the temperature of the turbine blades.

An incinerator operating efficiently should normally have only 1-2% O2 and 0-1% combustibles in the outlet gases. Monitors are available that can indicate these parameters to the operator as well as provide automatic control of the incinerator when required.

The environmental appHcations of infrared spectrometry are many and varied. Many appHcations at industrial sites are analogous to those for on-line process analysis waste streams and recycling processes can be monitored in the same way. Commercial infrared stack-gas monitors are based on either an extractive probe attached to a long-path gas ceU or an open-path (across stack) configuration (69). Stack plume and flare monitoring can be done externally...

Gas-monitoring systems are more widely used than particulate monitoring systems. They can also be used for both emission compliance monitors and process control systems. Gas monitors may be of either the in situ or... 

List the advantages and disadvantages of both in situ and extractive gas monitors. Discuss the advantages and disadvantages of one-time source testing for a specific emission versus conflnuous monitoring of the same emission.

We scrutinize issues dealing with requirements of high sensitivity and response selectivity of electrophysical parameters in reference to the gas monitored or the type of active particles under study as well as other requirements put forward to adsorbents of chemical sensors. We discuss principles underlying the basis of solving these problems. We dwell on the issue of the type of crystal of adsorbents examined, which is directly linked to the character of intracrystallite contacts. 

The overall system essentially consists of two separate systems (i) a constant pressure reactor system and (ii) a gas monitoring system. A schematic flow diagram for the overall system is provided in Figure 1.

In addition to the standard laboratory protection, such as safety goggles and chemically resistant butyl rubber gloves, a personal HF gas monitor with audible alarm and a safety sensor for liquids, as described in Section 10.4, are commercially available [2], For detailed information about the toxic effects of HF, see references Fi5, Wa8 and Re4.
