一、前言氯盐含量是原油性质的一项重要指标,原油在开采过程中由于地层中有盐层和水层,所以开采出来的原油均含盐和水。盐的存在对石油加工设备产生腐蚀。随着重油加工技术的发展氯盐中钠离子对催化剂活性的影响已成为突出的问题,因此在进行原油加工前,需对原油进行脱盐脱水处理,有的甚至需要二次脱盐,以严格控制原润的含盐量指标。为此,迫切要求建立一个准确、可靠、精度较好的测定原油中盐含量的标准方法 I. Preface Chlorine salt content is an important indicator of the nature of crude oil. Crude oil, both oil and water, is extracted from crude oil during the recovery process due to salt and water layers in the formation. The presence of salt corrodes petroleum processing equipment. With the development of heavy oil processing technology, the effect of sodium ion in chloride salt on the catalyst activity has become a prominent issue. Therefore, crude oil needs to be desalted and dehydrated prior to crude oil processing, and some even require secondary desalination to strictly control the original Moisture content of salt indicators. For this reason, there is an urgent need to establish an accurate, reliable and accurate method for determining the content of salt in crude oil
