Production of particleboards is associated with volatile organic compounds emissions, many of which have odorous properties. The objective is to determine whether the odor emissions from the production, using spruce and aspen as raw material, comply with the local odor limit defined in a specific way—an hourly average odor concentration leading to 16% odor annoyance and not being exceeded more than 2% of the time in residential area. Complex data of odor are presented from two largest sources—dryer and press, providing odor emission concentration, flow, composition, and dispersion model. The odor emission flow from the dryer is by factor of 19 higher with the value of 7655 × 106 ouE h−1 than that from the press. The dependence between odor concentration and annoyance is defined and determined. Identifying the top 10 odorous compounds (the most relevant are hexanal, butanoic and acetic acids, and α- and β-pinenes) in the emissions, the concentration, which leads to 16% annoyance, is quantified to 0.62 µg m−3. The dispersion model provides odor distribution, proving that the given limit is not exceeded in the nearby residential area.

刨花板生产厂的气味建模

刨花板的生产与挥发性有机化合物的排放有关，其中许多具有气味特性。目的是确定以云杉和白杨为原料的生产过程中的气味排放是否符合当地以特定方式定义的气味限制——每小时平均气味浓度导致 16% 的气味烦恼，并且不超过2%的时间在住宅区。气味的复杂数据来自两个最大的来源——干燥机和压榨机，提供气味排放浓度、流量、成分和分散模型。来自干燥机的气味排放流量比来自压力机的排放流量高 19 倍，值为 7655 × 106 ouE h-1。定义和确定气味浓度和烦恼之间的相关性。确定排放物中前 10 种气味化合物（最相关的是己醛、丁酸和乙酸，以及 α- 和 β-蒎烯），导致 16% 烦恼的浓度被量化为 0.62 µg m-3。扩散模型提供气味分布，证明附近居民区没有超过给定的限制。
