| 中文摘要: |
| 本文阐明了超声波原油破乳脱水基本原理．实验研究了超声场参数对脱水率的影响，其中，声强、辐照时间和频率是影响原油脱水率的主要因素，而间歇比、脉冲宽度为次要因素．对本实验系统而言，声场参数有一个最佳值或范围，声强 ０．６５Ｗ／ｃｍ２、频率 ２０ｋＨｚ、间歇比 ８、脉冲宽度９．７ｍｓ、辐照时间５－１０ｍｉｎ。 |
| 英文摘要: |
| The basic principle of crulde-oil dehydration by ultrasonic demulsiflcation is elucidated. Effects of the ultrasonic-field parameters on the crude-oil dehydration rate are experimentally studied as well. It was focused from the experiments that the acoustic intensity,time of irradiation and frequency are the primay factors which affect the dehydrated rate, while the ratio of intermittent and pulse duration are the secondary factors. In this experimental system, the optimum acoustic immensity, frequency, ratio of intermittence, pulse duration and time of irradiation are 0.65W/cm’, 20kHz, 8, 9.7ms and 5-10min, respectively. |
