Improving the economic and environmental performances of the beet Sugar industry in Slovenia: increasing fuel efficiency and using by-products for ethanol
Journal of Cleaner Production, 2007Co-Authors: Damjan Krajnc, Miro Mele, Peter GlavičAbstract:Abstract This paper investigates the possibilities of attaining zero-waste emissions in the case of Sugar production. The case-studied Sugar Plant located in Slovenia reflected a typical Plant, using traditional Sugar production from beet. An investigation of the possible use of waste and by-products from Sugar processing was carried out, in order to approach zero-waste from beet Sugar processing. The Sugar production process was simulated and optimization was carried out concerning energy utilization. Consumption of energy in the chosen Sugar Plant was lowered by simultaneous optimization of the evaporation and crystallization process. Changing the fuel type used in the case-studied Sugar Plant (replacement of heavy fuel oil with natural gas) produced a significant decrease in air emission. Opportunities in the Sugar industry have been discovered for adapting to new market conditions through the optimization of combined Sugar–ethanol production. The two proposed options have been economically and environmentally evaluated and compared.

water minimization in process industries case study in beet Sugar Plant
Resources Conservation and Recycling, 2005Co-Authors: žbontar L Zver, Peter GlavičAbstract:In this article, an extended and combined systematic approach for water minimization in process industries is presented. Environmental, organizational and economic aspects of water minimization were taken into consideration. Systematic approach was developed and tested with the water minimization project in a Sugar Plant. A detailed survey of water and wastewater streams was carried out and several options for water minimization were proposed using the heuristic approach and considering the selection criteria like costs, technical ability, reliability, complexity, impact on process/product quality, secondary waste generation etc. The implementation of water minimization options could lower the fresh water consumption by 54.23 m3/h, reducing the total volume of water used by 69 % with the payback period of 5 days. At the end, some general directions and suggestions for water minimization in process industries are introduced.

a techno economic cost analysis of a turbine power Plant a case study for Sugar Plant
Renewable & Sustainable Energy Reviews, 2017Co-Authors: Tolga Taner, M SivriogluAbstract:A general model (Sugar production processes) was developed based on data provided by a real Plant and provided an exergy analysis. It was explored for a techno-economical turbine power Plant and the improvement of performance indicators was achieved through thermoeconomic analysis. Unit cost for the turbine power Plant is found to be 3.142 [$ / kW]. The simple payback period of the turbine power Plant is calculated as 4.32 years. The purpose of this study is to reduce the cost of power Plant. At the same time, this study poses a thermoeconomic analysis to increase turbine power.

Energy consumption optimization in a Sugar Plant using pinch technology and linear programming
2017Co-Authors: Marcio HigaAbstract:Resumo: Através dos métodos do "pinch-point" e da programação linear, foram realizadas diversas simulações e análises térmicas de uma Planta típica de produção de açucar e álcool, visando a máxima recuperação de calor e a redução do consumo de vapor. As simulações foram divididas em três grupos. No primeiro, usou-se o método do "pinch-point" para investigar basicamente a Planta de produção de açucar, analisando também a influência de diversas alternativas (eliminação de sangrias de vapor entre estágios de evaporação, numero de efeitos de evaporação, compressão mecânica do vapor do ultimo estágio de evaporação, área e numero de trocadores de calor). No segundo grupo, na mesma Planta, empregou-se o método de programação linear, a fIm de determinar a distribuição otimizada das sangrias de vapor para pré-aquecimento do caldo. No terceiro grupo de análises, considerando também o consumo na produção de álcool, retomou-se ao método do "pinch-point", onde as sangrias foram primeiramente maxirnizadas nos ultimos estágios de evaporação e em seguida ajustadas para satisfazer as áreas dos evaporadores existentes na Planta básica. Para tanto, foi desenvolvido um programa de computador específico que permite a simulação do efeito das diversas variáveis, inclusive a razão de produção açucar/álcool. Diversas alternativas de grande impacto no consumo de vapor são apresentadasAbstract: Using pinch technology and linear prograrnrning, several simulations of thermal analysis of a typical Sugar cane Plant and alcohol production were performed. The objective was the maximum heat recovery and the reduction of steam consumption. The simulations were divided into three groups. In the fIrst, pinch technology was applied to analyze only the Sugar cane basic Plant production and the influence of several alte~natives (elimination of vapor bleed between evaporator effects, number of evaporator effects, mechanical compression of vapor in the last effect of evaporation, area and number of heat exchangers). In the second group, use was made of linear prograrnrningin the same Plant to determine the optimized confIguration of vapor bleeds for juice preheating. In the third group, pinch technology was again applied, including the consumption from alcohol production. First of ali, the maximum vapor bleed was assumed at the last effects of evaporation, then adjusted to adapt to the evaporator areas of basic Plant. Therefore, a specifIc computer programming was developed to simulate the several variable, including the ratio of production Sugar/alcohoL Several alternatives of deep impact in steam consumption were investigate

thermal integration of multiple effect evaporator in Sugar Plant
Applied Thermal Engineering, 2009Co-Authors: Marcio Higa, A J Freitas, Antonio Carlos Bannwart, Roger Josef ZempAbstract:Besides the largest energy consumption in the process of Sugar production, evaporation also presents many opportunities of thermal integration with the remaining of the process. That occurs due to the possibility of making use of the vapor generated during the evaporation operation (vegetal vapor), as a heating source, from extractions to process. Regarding the thermal integration of the multiple effect evaporator (MEE), previous studies showed that, in general, the energy recovery is usually larger when extractions are practiced in the last effects of the operation. Although the results found can be used for development of new projects, as heuristic rules, the application has been limited due to the lack of understanding on the subject. In the present investigation, a study was carried out by defining equations that can be used as a reference for thermal integration projects, including MEEs. The equations are also helpful for elaborating a systematic way to apply pinch analysis in Sugar Plant with an algorithm.
