摘要:

AbstractPrecipitation from Supercritical Gases. The importance of processing substances with supercritical gases as a separation method has increased in recent years, particularly as a means of obtaining products produced without organic solvents. This article surveys the various methods of depositing substances from a supercritical phase. The surest method, i.e. that of reducing the pressure to subcritical values, involves a high energy consumption for recompression of the phase when performed on an industrial scale. For this reason, isobaric deposition methods (adsorption, absorption, membrane separation) were examined to establish their suitability for regenerating the supercritical solvent.

摘要:

AbstractCatalytic Oxidation of Isomaltulose. In carbohydrate chemistry the noble metal catalyzed oxidation is known as a “clean” reaction with high selectivity. Applied to the disaccharide ketose isomaltulose, the reaction gives two monooxidized and one dioxidized products contrary to the selectivity rules, which were earned for monosaccharides byHeynsin fundamental investigations. However, the kinetic studies of this reaction show that the dioxidation is a two step reaction in which the second step is inhibited by high isomaltulose concentrations. This could be used for the development of a process of technical interest for preparing the monooxidized products because the continous removal of the ionic reaction products with an electrodialysis allowed the realization of optimal reaction conditions.Kleinet al. show that these monooxidized products are important intermediates for semisynthetic polym

摘要:

AbstractCombination of Mechanical and Thermal Drying. The first part of this paper presents the various hardware approaches to combining mechanical and thermal drying. The various solutions are illustrated by applications. The second part addresses cost optimisation in the combination of mechanical and thermal drying. The approach to cost optimisation is illustrated for the example of corn starch.

摘要:

AbstractPrinciples of Computer‐Aided Assembly Planning. The assembly planning for a chemical engineering plant defines the position of the individual machines and articles of equipment in an appropriate grid (Fig. 1). Apart from the demands of pipe routing, numerous widely differing, partly contradictory, boundary conditions influence the assembly of a plant. These include, among other factors, investment and assembly costs, ease of maintenance and operation, as well as safety and environmental protection. Thus numerous specialist areas are involved in this planning work, with the definition of the „optimum”︁ solution being based on individual studies and particularly on exp
