For the first time, it is possible to gain a detailed quantitative insight into the internal operation of multitubular reactors — complicated units that can be notoriously difficult to design because they involve complex catalytic reactions, a large number (often 2,0000 or more) of tubes, and closely coupled, shell-side heat transfer and hydrodynamics, says Mark Matzopoulos, marketing director at...

    The equilibrium phase distribution ratio (K value) is necessary for designing and assessing the performance of distillation columns. This paper proposes a simplified approach to calculate the K value that is suitable for preliminary design work and for checking the performance of existing columns. The article also explains the first principles for calculation of K values from the fugacity of...

    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...
