In plant layout

Hazard analysis (HAZAN) is a quantitative way of assessing the likelihood of failure. Other names associated with this technique are risk analysis, quantitative risk assessment (QRA), and probability risk assessment (PRA). Keltz [44] expressed the view that HAZAN is a selective technique while HAZOP can be readily applied to new design and major modification. Some limitations of HAZOP are its inability to detect every weakness in design such as in plant layout, or miss hazards due to leaks on lines that pass through or close to a unit but cany material that is not used on that unit. In any case, hazards should... 

Use gravity flow in plant layout where feasible to minimize the need for pumps or solids handling equipment for hazardous materials. Conduct a hazard review to assess the effect of layout on potential spills.

The use of computer models to assist in plant layout decisions can often be helpful, but a clear understanding of what they can and cannot do is needed. Used blindly, they can lead to solutions which are, in some sense, optimal but which have little practical merit.

This step constructs a specific set of search questions to guide identification of opportunities for material substitution, equipment modification/substitu-tion, changes in work practices and organization, modifications in plant layout, and changes in final product. 

In plant layouts without supplementary firing. 111 is limited by the resistance of the OC at high temperature, which limit the maximum temperature of the combined cycle and thus the maximum efficiency. Therefore, CLC processes will not take advantage of future advancements in the gas turbine material technology. 

The following general pattern in plant layout can be observed ... 

Access control and personnel movements are considered in plant layout to reduce the potential for spread of contamination. 

AHTR Differences. There are several differences in plant layout. 

The SCOR is mainly developed for electricity generation, providing competitive costs compared with large sized reactors through system simplification and compactness in plant layout. However, the SCOR may be used in cogeneration schemes like seawater desalination using low temperature processes, such as thermo-compression or multi-effect distillation. 

Although equipment types and the flow of process streams between the equipment types are the main drivers in plant layout, piping is also important—not least because it constitutes a major part of the overall cost of the complete facility.
