摘要:: 原油交接点的含水测定,目前大部分沿用手工法和蒸馏法,2h采样,4h人工化验,采样不具有代表性,化验方法带有人为干扰。为了克服上述缺点,中国计量科学研究院研制了SH—E型射频原油含水分析仪,实现了原油含水量在线连续测定、瞬时显示、2h取平均值打印,基本上排除了人为因素的干扰,使测出的原油含水率具有代表性。射频原油含水分析仪由射频法含水率测量传感器和以Z80单板机为核心的信号分析仪组成。射频法测量原油中的含水率是基于射频阻抗理论,由被测油水液对射频信号呈现的阻抗特性,反映含水率大小。该仪表具有测量范围宽、灵敏度高、稳定性好、安装简单、使用方便等特点。还有测量量程自动扩展、根据测量范围自动选择最佳精度的功能。通过一个多月的在线测量,与人工化验相比,仪表测量结果可信,与蒸馏法相比,具有省时、省力、节约能源等优点。

Abstract:: Up to now, the water content in crude at an interface point has been measured with manual method and distilling method, 2 hours for sample collection and 4 hours for experiment carried out manually. The collected samples are of no representitiveness, the method of chemical experiment is artificially interfered. To solve the above problem, China Measurement Research Institute has developed an analyzing meter of SH-E model for water content in crude analysis. Therefore water content can be measured on line continuously, instant display is available, it takes 2 hours to get and print out the average value. Artificial interferences can be avoided. As a result, the measured content of water in oil is of representitiveness. RF water content analyzer is only made up of a sensor of RF water content measurement, and a signal analyser with the Z80 single board computer as the core. RF method for measuring water content is based on the theory of RF resistance. The resistance characteristics of the oil/water liquid being measured to the RF signals shows the quantity of the water in oil. This instrument is wide in measuring range, high in sensitivity, good in stability, simple for installation and convenient for application. It also has the function of automatic expansion of measuring distance, automatic selection of the superior accuracy according to the measuring range. Through a month on line measurement, the instrument measuring result, compared with manual experiment, is convincible; compared with distilling methed, instrument measuring can save time, labour and energy, etc.
