Large-scale system, engineering

The chemical engineer is concerned with the industrial application of processes. This involves the chemical and microbiological conversion of material with the transport of mass, heat and momentum. These processes are scale-dependent (i.e., they may behave differently in small and large-scale systems) and include heterogeneous chemical reactions and most unit operations. Tlie heterogeneous chemical reactions (liquid-liquid, liquid-gas, liquid-solid, gas-solid, solid-solid) generate or consume a considerable amount of heat. However, the course of...

In order to study the potential for a runaway reaction, the investigator must be aware of the characteristics of the chemical reaction (s) as well as the characteristics of the actual large-scale system. In other words, a review of the hazards of an exothermic reaction requires a knowledge of both the "chemistry" of the reaction and the "engineering" of the large-scale system. 

For systems with a uniform temperature throughout the material, the "chemistry" and the "engineering" can be related through use of the Semenov Theory. (4) The rate of heat production was mentioned earlier as a kinetic parameter of interest and the heat transfer characteristics (in this case, rate of heat removal) as a large-scale system parameter. If the self-heating rate (rate of heat production) is determined as a function of temperature under adiabatic conditions and if there is a knowledge of the rate of heat removal as a function of temperature, information about safe operating limits for that particular system can be deduced. 

In order to be used on an industrial scale, membrane reactors need to be produced at a scale much larger than those currently employed in laboratory set-ups. This implies that membrane fabrication methods for large scale systems need to be defined, as well as the engineering related to module preparation. 

It is more than to think big or to intend a big development. It is also absolutely important to be experienced in design, engineering, building and commissioning of large scale systems and plants.

Aleksandar Kuzmanovic is Lisa Wissner Slivka and Benjamin Slivka Chair in Computer Science and assistant professor in the Department of Electrical Engineering and Computer Science at Northwestern University. His work is in computer networking and distributed systems with emphasis on design, measurements, analysis, denial-of-service resiliency, and prototype implementation of protocols, algorithms, and large-scale systems for the Internet. 

The principal technological changes in the engineering control of air pollution were the perfection of the motor-driven fan, which allowed large-scale gas-treating systems to be built the invention of the electrostatic precipitator, which made particulate control in many processes feasible and the development of a chemical engineering capability for the design of process equipment, which made the control of gas and vapor effluents feasible.
