摘要

这项研究采用能效学和功效经济学方法,对工业啤酒生产所涉及的组件和工段的性能进行了评估。该系统分为五个生产部分,并考虑了三种能源输入类型。能效研究表明,啤酒生产的运行能效为 3.33%,总能效破坏率为 5.54 兆瓦,具体破坏率为 9.72 千瓦/小时。总体改进潜力和可持续性指数估计分别为 4.98 兆瓦和 1.03。酿酒车间和包装车间被认为是生产效率最高的区域,分别为 58.73% 和 30.40%。经济效益研究表明,啤酒生产的成本率为 0.1704 美元/秒,其中麦汁釜、灌装机、Kieselguhr 烛式过滤器、漩涡池和硬质啤酒槽依次被确定为最重要的五个组成部分。系统的效率受到包装车间活动的严重影响,特别是那些涉及无法回收或无法归因于啤酒加工流的能源投入。还需要进一步研究,以确定从额外的蒸汽节流、缩小某些主泵的尺寸以及麦汁加热和啤酒冷却过程中的放能损失中确定的优化措施所节约的成本。

Exergetic and exergoeconomic analyses of a large-scale industrial beer processing system

This research evaluated the performance of components and sections involved in industrial beer production using exergetic and exergoeconomics methodologies. The system was segmented into five production sections, and three energy input types were considered. The exergetic studies showed an operational exergetic efficiency of 3.33%, with an overall exergetic destruction rate of 5.54 MW and a specific destruction rate of 9.72 kW/hl for beer production. The overall improvement potential and sustainability index were estimated at 4.98 MW and 1.03, respectively. The brewhouse and packaging hall were identified as the sections with the highest production inefficiency, 58.73% and 30.40%, respectively. The exergoeconomic studies revealed a cost rate of 0.1704 USD/s for beer production, with the wort kettle, filling and cocking machine, Kieselguhr candle filter, whirlpool, and brite beer tank identified as the top five significant components in descending order. The efficiency of the system was critically affected by the activities in the packaging hall, particularly those involving energy inputs that cannot be recovered or attributed to the processed stream, beer. Further research is required to determine the cost savings of optimization measures identified from additional steam throttling, downsizing of some main pumps, and exergy loss during heating of wort and beer chilling processes.
