By examining biodiesel and bioethanol, significant synergies can be seen in the production of these two biofuels and, for this reason, Dedini introduced the concept of 'Bioethanol-Biodiesel Integration' into the market in November 2004. The biodiesel installation is attached to and integrated into the sugar and alcohol mill, with a number of advantages, bringing cost reductions and minimised investments. In the agricultural sector, the concept of producing oil grains during cane renovation already exists, from which vegetable oil is extracted, i.e. the main feedstock for biodiesel. The second feedstock is bioethanol produced at the mill, and the integration enables optimisation by using existing installations, utilities and human resources. The energy is produced from sugarcane bagasse. A portion of the biodiesel produced fuels trucks, tractors and harvesters of the mill. Summarising, there is synergy in the cane crop and in the industry, as well as benefits in economics, energy and the production process. Considering such attractiveness, Barralcool Mill, in Brazil has built a biodiesel plant integrated into the mill, supplied by Dedini, which started operations in November 2006, with the following highlights: First in the world integrated with a sugar and alcohol mill; Flexible to use multiple feed stocks: vegetable oils and animal fat (beef tallow); World first continuous plant using ethyl route; and flexible to methyl route; 50 000 tonnes/year capacity. Barralcool Mill then becomes the first in the world producing 3 BIOs: bioethanol, biodiesel, and bioelectricity (surplus electricity produced from bagasse sold to the grid). This paper presents the Barralcool Mill case: biodiesel production using ethyl route, integration to the mill, and the derived benefits.","PeriodicalId":14415,"journal":{"name":"International Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70988744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlations for water content and dry substance allow for accurate control of concentration, Brix content and density in all areas of sugar production. This permits a continuous measurement during the complete crystallisation process, both in the solution and the magma phase. This report explains the measuring effect and signal analysis of microwave measurement systems and illustrates the user benefits, resulting in very good process control. Solutions are proposed for typical application problems such as incrustation, abrasion, purity dependencies and the recognition of breaks between crystallisation processes using the Micro-Polar Brix measurement system. Results acquired with different sensors in various processes and applications are presented. Besides the accurate and reliable measurement of all products from sugar beet or sugarcane, a high value is placed on simplicity, low maintenance and easy calibration to ensure optimised process control and cost. The automatic calibration feature, which requires no additional PC, is demonstrated.","PeriodicalId":14415,"journal":{"name":"International Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69789102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low capacity of available systems and consequently high investment cost as well as waste water and operating cost issues have been impediments that made softener implementations feasible only under particular circumstances. The introduction of waste free weak cation softening resulted in significant reduction of operating costs while the combination with fractal technology allows cutting down the process size dramatically. The paper provides information, which is helpful to re-evaluate the economics of thin juice softening. Therefore positively affected process areas are listed and general financial benefits from operating soft juice are assessed. More specific figures are given for different model cases, representing beet factories of various technological and energy efficiency standards with campaign lengths as typical for certain regions. A comparison of the results with the estimated installed cost of fractal weak cation softeners shows a good potential for this technology to become a standard unit operation for substantial parts of the beet sugar industry.","PeriodicalId":14415,"journal":{"name":"International Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2005-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70929597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Standard liquor filtration using a Putsch Sibomat filter","authors":"Douglas M. Petriw","doi":"10.5274/ASSBT.2005.85","DOIUrl":"https://doi.org/10.5274/ASSBT.2005.85","url":null,"abstract":"Standard liquor filtration is typically accomplished using diatomaceous earth (filter aid) as the filtering medium. The Putsch Sibomat filter offers an alternative that does not require the use of filter aid. Rogers Sugar Ltd (Taber) initiated a test starting in the spring of 2003 with the objective to test the effectiveness of the Sibomat in terms of filtrate quality and filter capacity and to identify whether elimination of filter aid could be achieved. Standard liquor filtration at Taber consumes on average 2 kilograms of filter aid per tonne of sugar produced, at a campaign cost approaching $100,000 Canadian. Elimination or major reduction in the filter aid consumption can produce an attractive economic payback. The Sibomat filter test unit supplied by Putsch was a full-scale assembly with only one filter basket. Fitted with a 55-micron screen element, it was installed in parallel with the factory's main filter station. Following testing during two juice campaigns and two beet campaigns, results to date indicate suitable beet campaign operation with significant filter aid savings, but unacceptable performance over both juice campaign periods. During the first juice campaign, filter aid contamination of the Sibomat feed contributed significantly to the poor results. Unfortunately, correction of this issue for the second juice campaign did not produce an acceptable improvement in filtrate quality. Very fine suspended matter in the stored thick juice could not be removed even after changing to a 33-micron screen element. After correcting a number of commissioning issues during the first beet campaign, the Sibomat handled up to 75% of the total juice flow (34 m 3 /hour average) producing suitable quality filtrate with acceptable cycle times (80 to 90 minutes). The consumption of filter aid was reduced by more than 50%. During the second beet campaign, intermittent performance issues were identified. This, plus higher average liquor flow, contributed to reduced filter aid savings. Although there is excellent potential for significant filter aid savings when using the Sibomat for beet campaign, current data suggests that total elimination of the diatomaceous earth filtration station cannot be recommended.","PeriodicalId":14415,"journal":{"name":"International Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2005-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70929671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Sugar policies opportunity for change","authors":"D. Mitchell","doi":"10.1596/1813-9450-3222","DOIUrl":"https://doi.org/10.1596/1813-9450-3222","url":null,"abstract":"Sugar is one of the most policy distorted of all commodities, and the European Union, Japan, and the United States are among the worst offenders. But internal changes in the E.U. and U.S. sugar and sweetener markets and international trade commitments make change unavoidable and provide the best opportunity for policy reform in several decades. The nature of reforms can have very different consequences for developing countries. If existing polices in the E.U. and the U.S. are adjusted to accommodate higher imports under international commitments, many low-cost producers, such as Brazil, will lose because they do not currently have large quotas and are not included among the preferential countries. The benefits of sugar policy reform are greatest under multilateral reform, and according to recent studies, the global welfare gains of removal of all trade protection are estimated to total as much as $4.7 billion a year. In countries with the highest protection (Indonesia, Japan, Eastern Europe, Western Europe, and the U.S.), net imports would increase by an estimated 15 million tons a year, which would create employment for nearly one million workers in developing countries. World sugar prices would increase by as much as 40 percent, while sugar prices in countries that heavily protect their markets would decline. Developing countries that have preferential access to the E.U. or U.S. sugar markets are likely to lose some of these preferences as sugar policies change. However, the value of preferential access is less than it appears because many of these producers have high production costs and would not produce at world market prices.","PeriodicalId":14415,"journal":{"name":"International Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2004-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
