Monitors processing facilities

Safety analysis concepts are discussed in this chapter by first describing a generalized hazard tree for a production facility. From this analysis, decisions can be made regarding devices that could be installed to monitor process upset conditions and to keep them from creating hazards. 

Analysis of results helps to anticipate facility and corporate managers concerns, enabling you not only to report progress but to propose useful solutions to problems you identify through the monitoring process. 

Modem process facilities are computer controlled. Temperature and AT are programmed upward during the start of a growth cycle, pressure and temperature are monitored and controlled, and pressure and temperature overshoot alarms and overrides are provided. Such systems also store data from previous runs for correlations with properties or for identical replication of past conditions. 

The 60-percent design specifies the detailed design basis, primary process steps, process flow diagrams, major equipment components, monitoring requirements, facility requirements (e.g., building layouts, electrical and ventilation requirements), and preliminary operational strategies. Detailed final specifications of all process components, facilities, and operations are not complete. 

The following items need to be considered for a successful on-line monitoring system and its economic use in a processing facility ... 

No monitoring data were located for hydrazine or dimethylhydrazines in ambient air. Since these chemicals are readily degraded in the atmosphere (see Section 5.3.2.1), they are not expected to be present measurable levels, except in the vicinity of production or processing facilities or spills. 

Detection methods applicable for commodity samples and in situ detection and monitoring in bulk storage and food processing facilities have been reviewed (Cotton and Wilbur, 1982 Fleurat-Lessard et al., 1994 Milner, 1958 Pedersen, 1992 Semple, 1992). Rajendran (1999) also studied infestation detection in stored foods and storage premises. 

Monitoring of the iodine content of salt produced for human consumption by means of sanitary inspections conducted at salt processing facilities. The assessment of iodine content in salt will be effected through sanitary inspection in industrial facilities and inspections in commercial establishments. 

The development of a detailed construction schedule is necessary for the coordination of the various contractors and monitoring the progress of the construction. A resource-loaded schedule for construction activities is necessary. Labor requirements must be evaluated from both availability and the density within the construction project. A general rule of thumb is to plan on one construction worker for every 200 gross square feet of building. In the case of compact process facilities, this can require spot density of one worker... 

Samples that contain numerous radionuclides from certain portions of the periodic table with short (1 h-lday) and intermediate half-lives. This mixture is found in monitoring process streams at operating nuclear facilities, fallout from nuclear tests, or accidents within hours to days after occurrence. Subcategories include samples from activation analysis, nuclear chemistry studies, and nature.

Department managers are responsible for determining the need for the development of turnover checklists to aid in the turnover process. Facility supervisors are responsible for periodically monitoring turnovers to assure formality and completeness and for conducting operations personnel briefings, as necessary. 

The first step is to benchmark the process units and identify performance gaps. This step helps focus the analysis on the best opportunities. It can also lead to operational improvements that can be implemented immediately. Energy monitoring application software is used to monitor the facility, identify performance gaps, and provide inputs to the detailed study and analysis step. Key indicator system and targets should form the basis for monitoring and control, which provides the means for continuous improvement. 

The uranium content in plants can serve for monitoring contaminants in the environment (Caldwell et al. 2012). Samples of plants, soil, sediments, water, and common biota were collected from flve distinct sites in the vicinity of a uranium processing facility with the objective of studying transport pathways and selecting the plants that are efficient bioaccumulators of uranium. Plant root samples were dipped... 

Knowledge evolves over time as research and development yields operational enhancements to process facilities. ISA-TR84.00.04-1 Annex R provides examples of key performance indicators that can be used to monitor aspects of the SIS lifecycle. Events involving abnormal operation may identify weaknesses in the risk-reduction strategy, leading to the need for more safeguards and improved performance metrics. New ideas identify ways to lower risk further.
