摘要：本文对山东玉皇盛世化工股份有限公司原料预处理装置电脱盐系统运行异常问题进行了分析，指出加强电脱盐源头罐区原油管理的重要性。针对所加工的重劣质原油，对该电脱盐系统进行了操作参数的优化调整，但结果仍未达到预期的脱盐效果。分析表明，仅通过操作工艺参数的优化调整、破乳剂的筛选来提高重劣质原油的电脱盐效果有限；在电脱盐罐体积一定的条件下，尽可能降低油流在电场内的上升速度才是突破电脱盐技术瓶颈的根本方法。因此，建议我国电脱盐成套设备研究公司结合国内外高效电脱盐的技术特点，研发新型高效的电脱盐技术，有效地应对现阶段原油重质化和劣质化、装置大型化的严峻挑战。
Abstract: This paper analyzes the abnormal operation of the desalting
system of raw material pretreatment unit of Shandong Yuhuang Shengshi Chemical
Co., Ltd., and points out the importance of strengthening the crude oil
management in the head tank area of electric desalination. The operation
parameters of the electric desalination system were optimized for the heavy
crude oil, but the results did not achieve the expected desalination effect.
The reason analysis shows that the electric desalination effect of heavy and
low quality crude oil is limited only by optimizing the operation parameters
and optimizing the demulsifier. Under the condition of the volume of the
electric desalting tank, the rising speed of the oil flow in the electric field
is reduced as much as possible Is the fundamental way to break through the
bottleneck of high efficiency electric desalination technology. Finally, it is
recommended that China's electric desalination complete sets of equipment
research company combined with domestic and foreign high-performance electric
desalination technology, research and development of new and efficient electric
desalination technology, effectively deal with the current stage of crude oil
quality and poor quality, large-scale installation of serious challenges.
