In Brewery Recovery of CO2 from Beer Fermentation

该项目将利用现有设备设计和建造一个原型二氧化碳捕获装置，该装置在小规模和间歇性规模上具有成本效益**。目标气流是一种在水蒸气中饱和的高浓度二氧化碳气体，例如在微型啤酒厂发酵罐中发现的气体。发酵罐可以捕获生物源性的二氧化碳，因此可以捕获气候中性的二氧化碳。二氧化碳捕获系统将需要对废气进行除湿，并捕获一部分排出的二氧化碳。确切的分数是一个设计问题，这取决于所需的二氧化碳质量，可用的即时储存和食品级质量所需的净化。挑战是**然后优化间歇性酿造计划的系统的资本成本。在啤酒厂中包含二氧化碳捕获步骤将需要压缩机和冷凝器，这两者都将产生显热。该研究将开发集成系统，该系统可以与现有的乙二醇系统一起工作，并利用室外温度来最大限度地降低系统成本。

This project will design and build a prototype CO2 capture unit from existing equipment that is cost effective**on a small and intermittent scale. The target gas stream is a high concentration CO2 gas that is saturated in**water vapor, such as found in a microbrewery fermenter. The fermenter would allow the capture of biogenic**and therefore climate neutral CO2. The CO2 capture system will need to dehumidify the exhaust gas and**capture a fraction of the exiting CO2.The exact fraction is a design question depending on the mass of CO2**needed, the immediate storage available and the required purification for food grade quality. The challenge is**then to optimize the capital cost of the system with an intermittent brewing schedule. The inclusion of a CO2**capture step in the brewery will require a compressor and condenser, which will both produce sensible heat.**The research will develop integrated system that can function with the existing glycol system and take**advantage of outdoor temperatures to minimize system costs.
