摘要:

为了解决目前油田站场敞口式污水池中可挥发性有机物(VOCs)散发问题,对物料平衡法、地面浓度反推法、排放系数法、类比估算法等VOCs计算方法进行介绍,对比和讨论了钢筋混凝土密闭、彩钢板密闭、玻璃钢板密闭、反吊膜密闭和全接液式浮盖等污水池密闭处理方法,并提出了不同密闭方式配套的VOCs回收和处理方案。通过对比可知,在对VOCs进行精确计算时,推荐采用物料平衡法和地面浓度反推法;在仅需要粗略计算时,推荐采用排放系数法和类比估算法。在污水池密闭工程中,推荐采用造价较低、施工方便、密闭性好、造型美观的反吊膜密闭方案;在污水池全部密闭的基础上,推荐采用造价较低、工艺较为简单的挥发气回收装置。

Abstract:

In order to solve the problem of volatile organic compounds (VOCs) emission in the open sewage tank of oilfield stations, this work introduces the calculation methods for VOCs, including the material balance method, ground concentration inversion method, emission coefficient method, and analog estimation method. Besides, the recycle of VOCs in different enclosed?sewage pools, such as reinforced concrete, color steel plate, glass steel plate, reverse hanging membrane and full wetted floating cover, were proposed. The results indicate that the material balance method and the ground concentration inverse method are recommended for a more accurate VOCs content calculation. In contrast, the emission coefficient method and the analogy estimation method are more suitable for a rough VOCs content calculation. In the project of the sewage tank, the anti?hanging membrane sealing scheme was suggested, due to its lower cost, convenient construction, good airtightness, and beautiful appearance. A volatilized gas recovery device can be used to collect the volatilized VOCs in the completely sealed sewage tank, because of its advantages in lower cost and a simpler process.
