Chemical plant design components

The data on probabilities given in this example are for illustration only, and do not represent actual data for these components. Some quantitive data on the reliability of instruments and control systems is given by Lees (1976). Examples of the application of quantitive hazard analysis techniques in chemical plant design are given by Wells (1996) and Prugh (1980). Much of the work on the development of hazard analysis techniques, and the reliability of equipment, has been done in connection with the development of the nuclear energy programmes in the USA (USAEC, 1975) and the UK. 

Pressure Vessels and Piping. Some of the most critical components of a chemical plant involve pressure vessels. A thorough knowledge of the American Society of Mechanical Engineers (ASME) Pressure Vessel Code (75) is essential for design and maintenance of chemical plants. Some states have their own codes, which usually conform closely to the ASME version (see High pressure technology Tanks and pressure vessels). 

It should be recognized that the total volume of wastewater as well as the chemical analyses iadicating the organic and inorganic components are requited, backed by statistical validity, before the conceptualizing of the overall treatment plant design can begia. The basic parameters ia wastewater characterization are summarized ia Table 2. 

In June, 1969, the indexes for the major components in the Chemical Engineering Plant Design Index were ... 

In this volume, there is an account of the basic theory underlying the various Unit Operations, and typical items of equipment are described. The equipment items are the essential components of a complete chemical plant, and the way in which such a plant is designed is the subject of Volume 6 of the series which has just appeared. The new volume includes material on flowsheeting, heat and material balances, piping, mechanical construction and costing. It completes the Series and forms an introduction to the very broad subject of Chemical Engineering Design. 

Estimating the inventory of reactants and anticipating their dynamic effects is fundamental in the design and control of chemical plants. The occurrence of nonlinear phenomena is often interrelated with the method of controlling the makeup of fresh reactants [8]. There are two methods for controlling the component inventory in a plant. By self-regulation the fresh reactant is set on flow control at a value given by the desired production rate. No attempt is made to measure or...
