ReDrop – A general method for solving drop- population balances with an arbitrary number of property variables
نویسندگان
چکیده
The simulation of liquid-liquid extraction columns has been of high interest for the last four decades. The well-known procedure is to solve drop-population balances. This approach reaches its limits if the additional influences like reactions shall be included in the simulation and can be solved only with extremely high mathematical effort. ReDrop (Representative Drops) is an alternative way to model extraction columns. The idea is to follow the path of a discrete number of individual drops along their way in a column and to change their attributes according to undergoing hydrodynamics, mass transfer, breakage and coalescence. The ReDrop algorithm was successfully applied to simulate the behavior of pulsed pilot-plant columns for EFCE standard test systems and also for technical systems. It has also been extended to reactive extraction.

Redrop – an Efficient Monte-carlo Method for Simulating Extraction Columns
Due to increase in the price of fossil fuels and the decrease in their reserves, renewable raw materials are industrially used more and more frequently. Therefore extraction, as an energy-saving unit operation has gained additional importance. Precise design methods for technical columns are required for the future. So far, pilot-plant experiments are carried out as a basis for equipment design...
متن کاملRobust Distributed Source Coding with Arbitrary Number of Encoders and Practical Code Design Technique
The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
