Chemical process industry structure

Corrosion-Resistant Binder for Fiberglass Composites. A second application of furan resins is as a premium, corrosion-resistant binder for fiberglass for fabrication of FRP structures for the chemical process industry. Structures can be easily fabricated using "hand lay-up" techniques used to fabricate polyester composites (see Figure 4). In this fashion, pipes, ducts, tanks, scrubbers, etc., are produced for use with process media which quickly... 

As the previous ehapter discussed nuelear power reactor operation and how to perform a PSA on it, this chapter attempts to apply a similar framework to chemical processing. The problem is the diversity of chemical processing that blurs the focus. This chapter begins by showing that accidents in the chemical process industry cost lives and dollars. Descriptions of deadly chemical accidents arc presented to show the chain of sequences that were involved to suggest how their PSA may be structured. Background on selected hazardous chemical process is presented followed by descriptions of how their PSA have structured. The chapter concludes by applying FTAPSUIT to a pressure vessel rupture analysis. 

With the developed concepts, a number of field experiments were conducted in the chemical process industry. A first experiment was carried out in a small company in The Netherlands. From this first trial, it was evident that the concepts of precursors, the model of the organisational control process and the structure of these concepts had to be adapted to obtain better and more reliable results. The improvements led to the development of a structured protocol of seven clearly defined stages. By applying this 7-stage protocol to the data of the small company, safety risks could pro-actively be identified and the accidents which the company had already experienced, could be explained. 

To verify the developed concepts underlying the structured 7-stage protocol in a reactive way, they were applied to an analysis of recent accidents in the Dutch chemical process industry. Despite the limitations in the information available from the accident database, it could be deduced that all accidents were preceded by precursors, and even that similar precursors had led to similar accidents, implying that companies had failed to learn from these re-occurring deviations which were in fact pre-warning signs of impeding accidents. 

Based on the observed problems in the measurement of safety in the chemical process industry, as outlined in the previous Chapter, additional research into this area is needed to provide companies with better indicators of possible accidents. In this Chapter the research methodology used to gain a more complete understanding of this measurement problem , is presented. This Chapter starts by discussing the focus, type and methodology of the research process. Then the research strategy and methods will be discussed to present the design structure of the complete research. 

In Chapter 5 the conceptual approach from the previous Chapter will be tested and evaluated and finally applied to a single case study in the Dutch chemical process industry. This exercise is performed to test the conceptual approach in practice. The findings of the case study will be evaluated and will lead to refinements in the conceptual approach. Finally a structured protocol will be derived and applied to the same case study to ascertain if the structured protocol is effective and suitable for practical use and leads to answering the research questions posed in Chapter 1. 

In Chapter 7 the derived structured protocol will be applied to multiple case studies in the Dutch chemical process industry. Three case studies will be conducted to derive the answers on the posed research questions and to confirm or reject the results from the case histories in the previous Chapter. The case studies will be carefully selected so that the outcomes of the analysis are predictable for all three cases. This replication strengthens the generalization and overall validation of all case studies and the research in general. 

The capability of chemical substances to undergo reactions, or transformations in their structure, is central to the chemical processing industry. Chemical reactions allow for a diversity of manufactured products. However, chemical reactivity can lead to significant hazards if not properly understood and controlled.

In this book the chemical plant is focused upon. Therefore, the present chapter emphasizes chemical reactors for the chemical process industry. But it should be made clear that structured packings and catalysts also have a large potential in consumer products. Chemical reactors form the heart of a (petro-)chemicals production plant. Given the large variety of plants it is no surprise that a wide variety of chemical reactors are used. Catalytic reactors can be roughly divided into random and structured reactors. It is useful to start with a summary of the major basic concerns (apart from high activity, selectivity, etc.) for catalytic reactors ...

ETFE resins in the powder and bead form are rotationally molded into varied structures, such as pump bodies, tanks, and fittings and linings, mostly for the chemical process industries. Inserts can be incorporated to provide attachment points or reinforcement.41 Adhesion to steel, copper, and aluminum can be up to 3 kN/m (5.7 pli) peel force.44... 

Other applications for THV are flexible liners (drop-in liners or bag liners), used in chemical process industries and other industries, and blow-molded containers, where it enhances the resistance to permeation when combined with a less expensive plastic (e.g., high-density polyethylene-HDPE), which provides the structural integrity.61 Optical clarity, excellent weatherability, and flexibility make THV suitable as a protection of solar cell surface in solar modules.63...
