Operational monitoring

Detection of Bromine Vapor. Bromine vapor in air can be monitored by using an oxidant monitor instmment that sounds an alarm when a certain level is reached. An oxidant monitor operates on an amperometric principle. The bromine oxidizes potassium iodide in solution, producing an electrical output by depolarizing one sensor electrode. Detector tubes, usefiil for determining the level of respiratory protection required, contain (9-toluidine that produces a yellow-orange stain when reacted with bromine. These tubes and sample pumps are available through safety supply companies (54). The usefiil concentration range is 0.2—30 ppm.

The foregoing demonstrates that modern digital devices offer highly reliable, state-of-die-art microprocessor technology that controls turbomachinery strings, monitors operating data, stores data for subsequent evaluation, communicates to odier systems, and can expand with future technologies. 

Lube oil level in the reservoir should be monitored by a sensing deviee to indieate low lube oil level. Loeal and panel-mounted pressure gauges are neeessary to monitor operation of the lube oil system and must be ineluded in the manufaeturer s seope of supply. The purehaser must distinguish between eontrol room instrumentation and instruments mounted on a stand-alone (loeal) panel. There is also a tendeney to plaee monitoring instruments on auxiliary equipment and piping. While this may eost less, it often eomplieates tlie operator s surveillanee tasks. 

Air microbial monitoring should be performed in and around areas of high operator activity. It is not unusual to see settle plates and air sample locations well away from such areas. A typical example is where settle plates are located well to the rear of the filling machine where there is little or no operator activity. The same may be true for air sampling. It is important, therefore, to observe operator activity over a period of time and ensure that the monitoring sites are located so as to monitor operator activity. 

Section Val. 1700 provides 14 exclusive procedures describing critical monitoring operations to ensure sterility assurance. 

Operator interface with system is via a two position operator s console. Each operator has two working color CRTs and a custom keyboard. A fifth single CRT dedicated to alarm displays is shared by both operator positions. Additional equipment includes multi-pen chart recorders, alarm logger and report typer. The operator monitors operations via continuously updated custom graphic displays, status and alarm reports on the CRTs and can call up displays and execute control commands by using special function push buttons in the keyboard.

The real power of thermography is that it allows us to quickly locate and monitor problems, and present critical decision-making information in visual form making it easy for management to understand. Infrared imaging systems, as they are generally called, produce a picture. . . of the invisible thermal pattern of a component or process. These thermal patterns, when understood, can be used to monitor operating conditions of equipment or processes. [14]...

An on-stream atomic absorption method for the determination of zinc and manganese in flotation liquors containing calcium sulphate has been reported [27]. The nebuliser to an air/acetylene flame was continuously fed, by gravity, with a portion of the process stream buffered with EDTA to overcome calcium sulphate interference. The atomic absorption monitor operated continuously for 3h before salting-up of the burner occurred. 

The MS detection technique is based on the ionization and fragmentation of an analyte. The mass analyzer separates the molecular ion and fragments according to their mass-to-charge ratios. Usually the detector output represents the total ion current produced by all fragments and molecular ions. Of course, this technique can be considered universal because all molecules can be sensed. However, if a particular ion that epitomizes a certain analyte (or class of analytes) is specifically sensed (via selected ion monitoring operation) while all other ions are disregarded, the technique becomes very specific. 

Facility managers use a variety of metrics to monitor operating, maintenance, and process safety performance at their site. These metrics often include a consolidated or aggregated view of metrics as well as some selected detailed data of interest. These reports can indicate the process safety system performance across the site and provide a performance comparison for individual operating units. This allows the site manager to compare performance among the site operating units and use this information to focus performance improvement efforts. Metrics reports often include but are not limited to items such as ...
