STTR Phase I: Continuous Monitoring Of Volatile Organic Compounds During Kiln Drying With The MEMS Chemical Sensors

这个小型企业技术转让(STTR)第一阶段项目的重点是开发一种监测木材加工过程中释放的挥发性有机化合物的监测器。将开发一种可以连续监测木材加工过程中污染物的MEMS探测器系统。与传统的监测方法相比，本文提出的方案将提供实时连续监测，总体上显著降低成本。胶合板和复合木制品在加工过程中释放出有害空气污染物的主要来源，包括乙醛、丙烯醛、甲醛、甲醇、苯酚、丙醛等。这些污染物与各种不良健康影响有关，包括鼻膜受损、胃肠道刺激、眼睛、喉咙和粘膜刺激、头晕、头痛和恶心。正在开发的化学电容传感器技术在木材加工以及许多商业应用中具有广泛的相关性。这些传感器是监控分布式系统中各种化学和物理目标的理想之选，在分布式系统中，重视及早发现问题。

This Small Business Technology Transfer (STTR) Phase I Project focuses on the development of a monitor for volatile organic compounds released during wood processing. A MEMS detector system that can continuously monitor pollutants during wood processing will be developed. The program proposed here will provide a real time continuous monitor with an overall significant cost reduction when compared to traditional monitoring methods. Plywood and composite wood products release major sources of hazardous air pollutants during processing, including, acetaldehyde, acrolein, formaldehyde, methanol, phenol, propionaldehyde and others. These pollutants are associated with a variety of adverse health effects including damage to nasal membranes, gastrointestinal irritation, irritation of eyes, throat, and mucous membranes, dizziness, headache, and nausea. The chemicapacitive sensor technology being developed has a broad relevance in the wood processing as well as a number of commercial applications. These sensors are ideal for monitoring a variety of chemical and physical targets in a distributed system where a premium is placed on early detection of problems.
