Analysis process engineering

After PRD contingency analysis, process engineer is required to fill out process information on the PRD data sheets, and give them to instrument engineers. The instrument engineer will add more information on the data sheets according to project PRD specification and his/her comments, and send them to vendors for bid. 

While the long chain hydrocarbons (above 18 carbon atoms) may exist in solution at reservoir temperature and pressure, they can solidify at the lower temperatures and pressures experienced in surface facilities, or even in the tubing. The fraction of the longer chain hydrocarbons in the crude oil are therefore of particular interest to process engineers, who will typically require a detailed laboratory analysis of the crude oil oomposition, extending to the measurement of the fraction of molecules as long as C3Q. 

A container full of hydrocarbons can be described in a number of ways, from a simple measurement of the dimensions of the container to a detailed compositional analysis. The most appropriate method is usually determined by what you want to do with the hydrocarbons. If for example hydrocarbon products are stored in a warehouse prior to sale the dimensions of the container are very important, and the hydrocarbon quality may be completely irrelevant for the store keeper. However, a process engineer calculating yields of oil and gas from a reservoir oil sample will require a detailed breakdown of hydrocarbon composition, i.e. what components are present and in what quantities. 

Safety Review. The safety review was perhaps the very first hazard analysis procedure developed. The procedure begins by the preparation of a detailed safety review report. The purpose of this report is to provide the relevant safety information regarding the process or operation. This report is generally prepared by the process engineer. A typical outline for this report follows. 

Many industries operated throughout the world do not fall into the previous categories. Some of these are universal, such as asphalt batching plants, whereas others are regional, such as bagasse-fired boilers. Each has its own emission and control problems and requires knowledgeable analysis and engineering. Some of the more widely used processes are examined in this section. 

A process engineer s task is often to evaluate the performance of a compressor unit based on gas throughputs and terminal pressures. Since compressor stations are complex machines and operations, the analysis required is sophisticated and goes well beyond simple computations on a personal computer, although some preliminary evaluations can certainly be made. In this section we summarize the working expressions for standard compressor operations. Compressor operations can be categorized under three thermodynamic categories ...

Not all product components are subjected to a load in fact most are not subjected to loads requiring an engineering analysis via engineering equations, etc. Experience in the material behavior on similar products and/or similar performance requirements are all that is needed. In these products designers become involved in their processing features that will prevent or reduce internal stresses, with elements that will lead to consistent and economical production, with appearance and dimensional control, etc.

Multiphase flow is important in many areas of chemical and process engineering and the behaviour of the material will depend on the properties of the components, the flowrates and the geometry of the system. In general, the complexity of the flow is so great that design methods depend very much on an analysis of the behaviour of such systems in practice and, only to a limited extent, on theoretical predictions. Some of the more important systems to be considered are ... 

Some data from corrosion-monitoring probes do not measure corrosion rate, but rather give other useful information about the system. For example, suppose conditions change dramatically during a process upset. An ejq)erienced corrosion engineer can examine the data and correlate it with the upset conditions. Such analysis can provide insight into the process and help to improve performance and extend equipment lifetime. Changes in simple parameters such as pH, ion content, and temperature may lead to detection of a process upset. Without careful analysis, process upsets can reduce the corrosion lifetime of equipment and even cause a system failure.

Control is considered at this point because there is an interaction between process control and design. A plant designed solely on the basis of a steady-state analysis may be very difficult to control. Therefore, the process engineer must consider what problems are likely to arise and how best to cope with them. Before he can do this, however, the engineer must decide which variables must be controlled.

For the student, this is a basic text for a first-level course in process engineering fluid mechanics, which emphasizes the systematic application of fundamental principles (e.g., macroscopic mass, energy, and momentum balances and economics) to the analysis of a variety of fluid problems of a practical nature. Methods of analysis of many of these operations have been taken from the recent technical literature, and have not previously been available in textbooks. This book includes numerous problems that illustrate these applications at the end of each chapter. 

Monitoring the course of chemical transformations during chemical processing and manufacturing is a crucial component of commercial activity. Desirably the analysis is in real time and with the required selectivity and sensitivity to adequately inform the process engineer. 

Finally, it is good to quote Shaw (1992, p. 227) the most important asset in a CFD analysis process is the analyst, who actually translates the engineering problem into a computational simulation, runs the CFD solver and analyzes the results. It is the skill of this person, or set of persons, that will determine whether all the hardware and software will be utilized in the best possible way and produce good quality results. CFD is certainly not a panacea that may solve all...
