| Summary: | 碩士 === 國立臺北科技大學 === 新能源電控產業碩士專班 === 101 === Biomass energy is a type of renewable energy. The primary application of biomass-converted energy engineering technology involves converting lignocellulosic organic material into sugar, employing separation, purification, and fermentation processes to generate biomass ethanol fuel, which can replace traditional fossil fuels.
In this study, an electromechanical automation system was designed and constructed to separate and purify membranes. Napier grass was used as the biomass material, to which a steam explosion treatment was applied, producing a mixture containing xylooligosaccharides. The objective of this study is to produce a xylooligosaccharide mixture that lacked a fermentation inhibitor.
The experiment comprised two phases. First, a total reflux method was adopted to plan, design, construct, and test a filtration membrane separation and purification system. Based on the composition and concentration ratios of the resulting steam explosion liquor, commercially available drugs were used to produce a simulated xylooligosaccharide mixture sample. Next, a total reflux operation was used to evaluate the separation effectiveness of filtration membrane in the separation and purification system. Second, instrument control components, devices, and a human-machine interface (HMI) apparatus that comprised an operator panel logic controller (OPLC = HMI + programmable logic controller) are employed. A temperature monitoring system was used to regulate and control the temperature of the circulating fluid of a filtration system, maintaining a constant filtrate temperature. An automated instant water replenishment system was used to maintain the xylooligosaccharide concentration levels of the circulating fluid in a certain range, facilitating optimal percolation. The experimental results provide relevant information, such as process parameters and filtration effects, which facilitates the goal of producing commercialized filtration-membrane separation and purification system in near future.
