摘要:

AbstractMulti‐product plants are very flexible units which are finding increasing use in the chemical industry, e. g. for the production of fine chemicals, pharmaceutical active compounds and automotive paints. Various concepts have become established for multi‐product plants, depending on the area of use and existing conditions. Technical equipment fitting in with these plant concepts is characterized by standardization, multi‐product suitability and a particularly broad area of use. The paper describes four multi‐product plant concepts and suggests criteria for selecting the suitable concept for a particul

摘要:

AbstractBatch processes being increasingly used in the chemical industry. The advantages of batch processes are their flexibility, high product purity and the possibility of frequent product changeover. For the economical operation of a batch process it is necessary to develop an optimal strategy; therefore a proper optimisation approach is required. For this reason two different optimisation algorithms, differential dynamic programming and a simultaneous optimisation approach, are investigated in this paper. The characteristics of the algorithms are worked out and their efficiency is analysed. Simulation results from batch reactors and a batch column demonstrate the scope of application of the algorithms.

摘要:

AbstractIn many natural and industrial processes the thermodynamic properties of aqueous electrolyte solutions play an important role. Systems of interest are frequently characterized by a large number of components and possible reactions. Due to low solubility, some reaction products precipitate as solids. The thermodynamic modelling therefore implies the computation of simultaneous phase and chemical equilibria. The minimization of the Gibbs free energy and theK‐value method are powerful algorithms for numerical computation and permit the simulation of complex electrolyte systems. The behaviour of the liquid solution has to be described by suitable activity coefficient model
