摘要:

AbstractThe decision‐making process in an expert group involved in solid‐liquid separations cannot be covered by a monolithic methodology or software. The analysis of typical problem‐solving processes shows the experts' knowledge requirements and turnover. According to the proposal in the present paper, these requirements are covered by a three‐tier computer‐based knowledge supply comprising databases, simulation programs and hypertexts. Software details of a typical simulation program for continuous vacuum filtration on belt filters are presented. In addition, a hypertext‐based electronic handbook on equipment scale‐up and design is described. This handbook represents an easy‐to‐use reference manual for empirical knowledge in the expert group. The above‐mentioned tools enhance work quality and efficiency in the expert group; knowledge is pre‐served and easily accessible. The tools allow rapid training of newcomers. In a crossfunctional team effort, the solid‐liquid separation expert can provide rapidly we

摘要:

AbstractThe design of an integral safety valve‐ blow‐off pipe system embraces the following essential steps: 1. An incident scenario must first be defined. All reasonable deviations from proper operation of plant must be considered. 2. The flow state at the entry to the safety valve must then be ascertained (one‐phase or binary flow); and 3. the minimal mass flow from the plant component to be protected must be calculated. Independently thereof, it is necessary 4. to determine the mass flow density in the blow‐off pipe system; it is usually related to the cross‐sectional area of the valve seat. The ratio of the two quantities gives the minimum necessary blow‐off cross‐sectional area. 5. In the final step, the pressure drop in the feed line and the counter‐pressure at the valve exit must be examined in order to assure reliable functioning of the valve also in conjunction with the pipe system. Steps 1. to 3. are considered in this article, and steps 4. and 5. will be addressed in Part 2 to be published in this journal. Appropriate recommendations and the necessary equations are given for each step. The main emphasis is placed on applicability of t

摘要:

AbstractThis review shows the relationship which exists between certain applications related and physical properties of dispersions. It also presents the possibilities at our disposal for determining such properties and influencing them in a desired manner. However, the available knowledge and methods are not sufficient for complete prediction of applications‐related properties. Gaps in our knowledge and in the experimental possibilities are indicated. What is feasible is demonstrated with the aid of some typical examples. The example are selected so that certain properties of the dispersions, such as particle size, rheological behaviour, or charge behaviour exert a pronounced influence on the applications‐related properties. The examples cover various material systems, such as emulsions, polymer dispersions, dispersions of active principles, and inoganic pigments. In conclusion, the article considers what knowledge and methods will be required in the future for more purooseful product develoom
