摘 要: | 中国石油化工股份有限公司洛阳分公司延迟焦化装置分馏塔顶的酸性水中有0.6%~2.0%(质量分数)的轻油组分,存在于酸性水中的污油不仅会对该装置及下游污水处理装置的正常生产造成影响,同时也会造成轻油组分的损失及环境污染。通过对静态旋流除油技术和动态旋流除油技术的对比分析,选用了操作弹性大、对操作压力要求低的动态旋流除油技术,用该技术对分馏塔顶酸性水中的污油进行分离,按分馏塔顶酸性水中的油质量分数可由6 000~20 000μg/g降至300μg/g以下,预计每年可回收污油1 500 t,产生经济效益560万元/a。

Abstract: | There is 0.6% ~ 2.0% light oil compoments in the sour water from the overhead of the fractionation tower of the delayed coking unit in SINOPEC Luoyang Company.The waste oil in the sour water not only affects the normal operation of the unit and the downstream waste water treatmentplant,but also causes the loss of light oil components and environmental pollution.After comparison and analysis of the dynamic hydrocyclone separation technology and static hydrocyclone separation technology,the dynamic hydrocyclone separation technology with greater operation towndown ratio and without higher pressure requirement is selected.After application of this technology,the oil in sour water from fractionator overhead is lowered from 6 000 ~ 20 000 ppm to less than 300 ppm.The oil in the sour water is greatly reduced,1 500 tons of waste oil can be recovered,and annual economic benefit is about 5.6 million Yuan (RMB). |
