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集器，在小规模和间歇性规模上具有成本效益**。目标气流是一种高浓度的二氧化碳气体，饱和在**水蒸气中，如在微型啤酒厂发酵罐中发现的那样。发酵罐将允许捕获生源二氧化碳，从而实现气候中性二氧化碳。二氧化碳捕集系统将需要对废气进行除湿，并捕获一小部分退出的二氧化碳。准确的二氧化碳捕集系统是一个设计问题，取决于所需的二氧化碳质量、可立即储存的二氧化碳以及食品级质量所需的净化。挑战是**然后用间歇性的酿造时间表来优化系统的资本成本。在啤酒厂加入二氧化碳捕集步骤将需要压缩机和冷凝器，两者都会产生显热。**这项研究将开发能够与现有乙二醇系统一起运行的集成系统，并利用**室外温度将系统成本降至最低。

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.
