摘要:
针对炼油厂采用气浮法处理含油废水过程中产生的油泥浮渣处置难题,采用微波热解法分离油泥浮渣中的石油烃,达到油分回收的目的。考察了微波功率、泥水比和微波时间对热解效率的影响。利用响应面分析方法优化微波热解工艺参数,并对油泥热解产物进行成分分析。结果表明:微波热解各工艺条件对油泥除油率和油分回收率的影响程度从大到小为微波功率,微波时间,泥水比。微波功率300 W、微波时间4 min、泥水质量比4:5时,油泥浮渣平均除油率可达58.03%,并可回收8.12%原油。扫描电镜显示微波热解后,油泥浮渣微观形态改变明显,泥渣表面平滑且孔隙较小。气相色谱法分析表明石油烃各组分显著下降。红外光谱表征分析处理后的油泥浮渣和回收的原油,油泥浮渣中的酰胺类化合物、有机芳香化合物以及芳香族氨基酸等官能团特征峰均大幅度减少。
Abstract:
In order to solve the treatment problem of a large amount of sludge scum produced in the process of treating oily wastewater by air flotation in refinery, microwave pyrolysis was used to separate petroleum hydrocarbons from sludge scum and achieve the purpose of oil recovery. The effects of microwave power, mud-water ratio and microwave time on the pyrolysis efficiency were investigated. Use response surface analysis method to optimize microwave pyrolysis process parameters and analyze the composition of the pyrolysis products of oil sludge. The results showed that the influence of the microwave pyrolysis process conditions on the oil removal rate and oil recovery rate of oil sludge from strong to weak is microwave power, microwave time, and mud-water ratio. When the microwave power is 300 W, the microwave time is 4 min, and the mud-water ratio is 4:5, the oil removal rate of sludge scum can reach 58.03% and 8.12% of crude oil can be recovered. Scanning electron microscope display observation, after microwave pyrolysis, the microscopic morphology of sludge scum has changed significantly, and sludge surface is smooth with small pores. Gas chromatography analysis showed that the components of petroleum hydrocarbons decreased significantly. Infrared spectroscopy was used to characterize and analyze the processed sludge scum and recovered crude oil. The characteristic peaks of functional groups such as amide compounds, organic aromatic compounds and aromatic amino acids in the sludge scum are greatly reduced.
