Chemical process industries expansion

A bold step by universities is needed if their chemical engineering departments are (1) to help the United States achieve the preeminent position of leadership in new technologies and (2) to keep the highly successful U.S. chemical processing industries at the forefront of world markets for established technologies. The universities should conduct a one-time expansion of their chemical engineering departments over the next 5 years, exercising a preference for new faculty capable of research at interdisciplinary frontiers. 

Loss data5 published for losses after 1966 and in 10-year increments indicate that the total number of losses, the total dollar amount lost, and the average amount lost per incident have steadily increased. The total loss figure has doubled every 10 years despite increased efforts by the chemical process industry to improve safety. The increases are mostly due to an expansion in the number of chemical plants, an increase in chemical plant size, and an increase in the use of more complicated and dangerous chemicals. 

The remainder of this Chapter 3 is organized as follows. In Section 3.2 we will provide a literature review of process expansions and multisite planning and coordination studies in the chemical process industry. Then we will explain the problem statement and proposed model formulation in Sections 3.3 and 3.4, respectively. In Section 3.5, we will illustrate the performance of the model through various industrial-scale refinery examples and scenarios. The chapter ends with some concluding remarks in Section 3.6. 

Our consistent need to improve our daily lives also led to unanticipated industrial developments. For example, the production of automobiles led to expansion of the oil production (or vice versa) and metal working industries, both of which account for pollution by several compounds cited on the contaminant list. The chemical processing industry has been responsible for many items we now consider the essentials of modem life. From plastics to modem electronic devices, the chemical industry has guided and benefited from developments and also exerted colinear effects on the contamination of air and water. Again, the development of remediation technologies is needed to establish an acceptable equilibrium. 

After the Second World War, the expansion of the petroleum refining and chemical process industries far outstripped that of the rest of the manufacturing industries. The chemical industry also was different than the older established industries due to the nature of toxic and flammable liquids and gases. [12] Naturally, the handling and storage of hazardous materials presented a potential peril that was often far greater than those posed by the traditional industries. 

This entry addresses lubrication in the context of a modern maintenance organization in the chemical process industry. Less emphasis is placed on the selection of lubricants as this subject is expansive and exceeds the scope intended for this entry. Instead, emphasis will be on the activity of lubrication, which falls in the domain of those charged with the responsibility of maintenance and machine reliability. Lubrication deals with stability of the lubricant within the machine in controlling friction, wear, and heat generation, among other things. 

In the chemical process industries, an investment project may arise from any of a range of activities. It may be a minor modification to an existing plant, a major plant expansion or revamping, a completely new plant (on an existing or greenfield site) or the development of an entirely new process or product. For a major or a new plant, economic... 

Stability, fluid compatibility and fatigue resistance also are associated with wear resistance. Vibration and pulsation in mechanical systems, or pipelines are common in chemical process industries and can lead to leakages of corrosive fluid. The vibration fatigue is an unavoidable factor which is further aggravated by improper installation of the moving system. Leakages due to these pulsations can be prevented by the installation of flexible rubber expansion joints. 

The excellent reviews by Hobman (1984), Zadow (1984), and Short (1978) should be consulted for specific references to the above-mentioned products and processes. The expansion of biotechnology applications to agricultural areas should aid in increasing utilization of lactose as an industrial chemical. 

During the first quarter of the twentieth century, the application of distillation expanded from a tool for enhancing the alcohol content of beverages into the prime separation technique in the chemical industry. This expansion accelerated once distillation was recognized as an effective means of separating crude oil into various products, From there, the application of distillation spread into the majority of chemical processes, Detailed descriptions of the history of distillation, including illustrations of historic exhibits, are given by Fair (1), Underwood (2), and Forbes (3). 

Most transgenic oilseeds with altered fatty acid composition remain research subjects, with commercial introduction limited to two crops, neither of which have yet achieved success in the marketplace. The expected benefits from transgenic crops with altered fatty acid composition include improved stability properties enhanced nutritive value expanded use of renewable resources to replace petroleum derived materials replacement of chemical processes, such as epoxidation of fatty acid double bonds and gradual expansion of agriculture as a chemical industry, a concept long ago known as chemurgy. It is possible to predict some issues that... 

As the range of temperature in chemical processes may vary from well below 0 °C to several hundred degrees centigrade, a wide range of measuring techniques has been evolved. The common mercury-inglass thermometer, which depends on the expansion of the liquid when heated, is not often used in industry. Thermometers of this type, with steel containers filled with mercury or other suitable liquid (such as alcohol for low-temperature measurement), may be conveniently used, particularly if fitted with some means of remote measurement.
