摘要

近二十年来,海水中原油污染的治理一直是全球关注的焦点。在温度、原油重力、震动频率、管道直径、油层初始厚度等不同条件下,采用圆形管道作为机械手段对海水中溢油进行清理。为此,设计并建立了实验模型。它由装有温度控制器的摇晃水浴(代表海浪)和内径为0.3厘米、0.5厘米和0.7厘米的玻璃管组成。以35°API、38°API和47°API三种不同含油度的原油为研究对象,在不同管径、20、40和60冲程/分钟的振动频率下进行研究。结果表明,采用圆形管道对溢油进行机械清洗是一种实用的技术。黑油泄漏的清理比挥发性油的清理更有效。此外,研究结果表明,增加振动频率和水温可以更快地清除泄漏的石油,而温度升高则可以回收最大的石油。

Mechanical Cleaning of Oil Spills in Seawater Using Circular Conduits
Treatment of the crude oil pollution in seawater has attracted global attention during the last two decades. This study was undertaken using circular conduits as a mechanical means to clean oil spills in seawater under different conditions of temperature, oil gravity, shaking frequency, conduit diameter, and initial thickness of oil layer. An experimental model was designed and built to achieve the study. It consists of shaking water bath (to represent sea waves) fitted with temperature controller and glass tubes of different inside diameters of 0.3 cm, 0.5 cm, and 0.7 cm. Three crude oils of different oil gravity of 35°API, 38°API, and 47°API were investigated under different shaking frequencies of 20, 40, and 60 stroke/minute with different tube diameters. The results proved that application of mechanical cleaning of oil spills using circular conduits is a practical technique. The cleaning of black oil spills is more efficient than one of volatile oil. Furthermore, the results indicated that the increase of shaking frequency and/or water temperature provide(s) faster cleaning of oil spills while temperature increase recovers the maximum oil.
