Process analysis analyzer environment

The SWOT analysis shows the output of previous analyses which were done in order to assess the company s internal and external situation within its industry. The process of analyzing the company and its environment can help to further assess the implementation factors of the supply chain differentiation process. This will give an overview of the company s strengths and weaknesses as well as its environment. 

At this juncture, it is necessary to define what will be considered under the title of process Raman spectroscopy in the industrial environment. Quality assurance/quality control (QA/QC) applications and failure analysis are important areas of industrial interest however, these areas, in general, can be adequately addressed with standard laboratory Raman spectrometers including FT-Raman spectrometers and dispersive microprobes. For the purpose of the remainder of this chapter, the industrial environment and the process Raman analyzer will be restricted to instrumentation and protocols usable for on-line measurements. At this point, it is necessary to outline a definition of what the requirements for an on-line process Raman analyzer are. A process Raman analyzer should be composed of components which have the following properties ... 

One of the main advantages of a fiber-coupled process Raman analyzer is the ability to put the sampling probe at the process, where conditions can range from mild to relatively harsh, and the analyzer in a controlled environment outside the direct process area. Fiber-coupled sample probes are currently used in both the laboratory and the control-room areas, which do not place much strain on the operation of the probes, but the major site of installation for process analysis is on-line. These environments can include elevated temperatures, pressures, and corrosive materials. 

Ideally, all jobs should be subjected to a JHA. In some cases there are practical constraints posed by the amount of time and effort required to do a JHA. Another consideration is that each JHA will require revision whenever equipment, raw materials, processes, or the environment change. For these reasons, it is usually necessary to identify which jobs are to be analyzed. Even if analysis of all jobs is planned, this step ensures that the most critical jobs are examined first. 

This chapter shows that chemical process systems may fail and have serious consequences to the workers, public and the environment. Comparing with Chapter 6, chemical processes are similar to the processes in a nuclear power plant, hence, they may be analyzed similarly because both consist of tanks, pipes heat exchangers, and sources of heat. As an example of analysis, we analyze a storage tank rupture. 

Comparative and phylogenetic considerations such as those outlined in the preceding paragraphs readily lead to speculation that the olfactory systems of modern animals share common antecedents and therefore probably also share common principles of functional organization and information processing. We might ask, What attributes of chemical stimuli do olfactory systems analyze and encode How are those features mapped in "neural space" at various levels of the olfactory pathway How are cells of the pathway organized, and what mechanisms do they use, to accomplish this analysis of odors in the environment ... 

By far the most widespread use of NMR in an on-line production environment is the utilization of downhole exploration tools by petroleum service companies such as Schlumberger, Halliburton, and Baker Hughes. Articles on these unilateral NMR systems are found in the patent databases, " academic literature, and on-line resources provided by the exploration companies. The references provided here are just a few examples in a very prolific field. The technique is applied in high-temperature and pressure situations and currently is used down to a depth of about 10 km (6 miles) to produce a picture of water/oil content in the adjacent rock formations as well as to derive permeability, diffusivity, and hydrocarbon chemistry information. Mobile unilateral NMR systems such as the NMR-MOUSE are also being developed in order to take benchtop NMR systems into the field to perform analysis of geological core samples at the drill site. NMR analyzers are also being developed to determine the bitumen content and properties in tar sand production and processing. " " ... 

The miniaturized conditions provided a suitable setting for this reaction, affording several important benefits. First, in microreactor environment this highly exothermic process demanded no additional cooling, whereas the reaction in batch needs to be conducted at 0°C. In addition to this, instant TOF-MS analysis proved the formation of the nitrilium cation intermediate, thus proving the reaction mechanism that was speculative until then. Another advantage of the reactor directly connected to the analyzer is the convenience and the speed of the reaction optimization.
