Energy usage in Beet Suger Factories. Sockerfabrikens energianvaendning; En systemstudie

Thesis/Dissertation:

Abstract

A computer program has been developed in order to simulate the energy consumption of beet sugar factories, for various plant configurations. The program is divided into five block units: Extraction and Juice purification, Juice concentration, Crystallization, Drying and finally the Power House. Each block consists of different modules, for example, a heat exchanger, an evaporator, a turbine and a dryer. The purpose of this project was to simulate some different system configurations of a sugar factory, whereby both new and previously used process technologies were utilized. The following parts of the process have been particularly emphasized: Power House - gas turbine, waste heat boiler. Drying - low-temperature dryer, steam dryer. Evaporation - vapour recompression. Crystallization - vapour recompression, continuous system. The different plant configurations have been compared to a reference factory, which is designed according to current technology used in a modern and well balanced Swedish factory. The comparisons are based upon the total power consumption as well as the total annual energy costs. Eleven different plant configurations were studied. The maximum power reduction is 36%, relative to the reference factory. The dissertation also contains an experimental study of a low-temperature drying process.

The drying characteristics of pressed beet pulp were studied in a specially designed rotary dryer pilot plant. A number of parameters were varied i.e. the solid moisture content, air velocity, temperature and rotational speed. The results are given in terms of an apparent volumetric heat-transfer coefficient, determined from measured data. A mathematical model was established to determine the residence time of the material in the rotary dryer at different air velocities. (45 refs.).}
