    Predicting an adiabatic-temperature rise is useful to chemical engineers for a number of purposes. One use is with combustion reactions whereby it is useful for determining the adiabatic-flame temperature. The adiabatic-temperature rise can be calculated for any reaction of interest, and thus it is often useful in the analysis and design of reactors. The adiabatic-temperature rise is also...

    For companies in the chemical process industries, water is an indispensable utility. But the growing scarcity of quality industrial water, combined with stricter environmental regulations and the rising cost of wastewater treatment, have encouraged the conservation of water as a key utility in process plants. Concurrently, the development of systematic techniques for water reduction has made...

        Vapor pressure is important to engineers throughout the chemical process industries (CPI). Knowledge of a compound's vapor pressure is required in the design of storage vessels containing the compound. In hazard analysis, knowledge of vapor pressure is required in the design of the relief valves to protect the system. For design of vapor-liquid operations, such as distillation...

    More and more, it is recognized that business and science are interwoven, and that these disciplines can complement each other to achieve corporate goals. In the chemical process industries (CPI), a noteworthy role is that of engineering in helping management comply with regulatory policy. A common procedure for most process engineers is performing a mass balance around a given system. Once...

    Since their inception, data buses have been highly acclaimed in the chemical process industries (CPI) for their potential to achieve interoperability and substantial wire-savings - advantages that are particularly easy to envision for a theoretical case in which a plant is constructed from the ground up and communicates by a single data bus. In the real world, however, the majority of...

    Minor components trapped in distillation columns can react to form solids that cause major problems. The conventional responses to this situation focus upon dealing with the solids after they have become formed. A better strategy consists of preventing or minimizing the solids formation in the first place, by changing the column operating conditions.   Understanding the situation The...
