络合型浮选剂的合成及应用

The Complex Type of Flotation Agents of Synthesis and Application

针对渤海油田流程处理现状,开发合成了一种络合型的浮选剂。综合考察了物料质量份数、引发剂质量份数、反应温度对产品性能的影响。结果表明最佳的实验条件是:单体质量份数7%(DM、阳离子单体W的质量为4∶3),络合剂P质量份数5%,引发剂的质量份数0.3%,乙二醇的质量份数8.5%,氯化钠质量份数1.5%,介质S的质量份数为3%,其余为去离子水,反应温度30℃,其中质量份数指占反应物总质量分数。同时,在渤南34-1油田现场应用,加药点选择在气浮悬除油器入口,结果表明:当络合型浮选剂加药浓度为30 mg/L时,清水除油效果显著。气浮悬除油器出口污水含油量由最高的75.5 mg/L降为加药后的1.5 mg/L,其平均除油率为84.4%,最大除油率为98%。

In bohai sea oil field flow process present situation,development synthesis a complex type of flotation agents.The influences of stabilizer concentration,monomer concentration,initiator concentration,agitation speed,reaction temperature were studied.It was shown that the optical experimental conditions were monomer concentration 7 wt%,complexing agent P wt 5 %,initiator 0.3 wt %,sodium chloride 1.5 wt %,ethylene glycol1 8.5 wt %,medium S concentration 3 %,reaction temperature 30 ℃.With a dosage of 30 mg/L synthesis flotation agent,clear water degreasing effect significantly.FuXuan except the outlet gas oil wastewater by the highest oil content down to 75.5 mg/L after dosing of 1.5 mg/L,its average except oil rate was 84.4 %,the biggest oil removal rate was 98 %.
