        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...

    Piping-flexibility and stress analysis are required in the design of most piping systems before the piping is installed in a chemical-process or other plant. It is intended to ensure the safety of the plant and thus protect the interests of the owner and the general public. Owing to the availability of powerful computer software packages, the analysis has become simple and routine. However...
