    摘要:

    以丙烯酰氯、对氨基苯甲酸为原料,通过酰氯胺解反应及中和反应合成单体对丙烯酰胺苯甲酸钠(a),并以过硫酸铵/亚硫酸氢钠为复合引发剂,以自制的对丙烯酰胺苯甲酸钠和甲基丙烯酰氧乙基三甲基氯化铵(DMC)为单体通过水溶液自由基共聚法合成了二元聚合物(b)。利用延长原油模拟的原油乳液对聚合物的破乳性能进行了考察,同时研究了聚合物的絮凝性能和对含油废水的除油效果。结果表明,在破乳温度70℃、处理时间2h的条件下,当聚合物(b)投加量为110mg/L时,脱水率达92.04%;同时在室温下,当自制聚合物投加量为12mg/L时,硅藻土悬浮液上层清液的絮凝时间为9s,透光率为98.6%;在聚合物投加量为30mg/L、温度为50℃、处理时间为7h的条件下,对含油废水的除油率达94.5%,因此,与市售破乳剂BQ-05、SP-169及市售絮凝剂PAM、PDMC相比,自制聚合物具有良好的絮凝-破乳性能。

    Abstract:

    Sodium benzoate of p-acrylamide (a) was synthesized by amine hydrolysis reaction and neutralization reaction,redox initiator of ammonium persulfate /sodium bisulfite,a binary copolymer (b) was synthesized with sodium benzoate of p-acrylamide and methacryloxyethyl trimethyl ammonium chloride as monomers.Using Yanchang heavy oil simulated heavy oil emulsion to evaluate the performance of homemade tetrapolymers demulsifier.The flocculation and oil removal performances of binary copolymer were also investigated.The results showed that under the condition of demulsification temperature 70℃,demulsification dosage 110 mg /L ,demulsification time 2 h,the dehydration was reached up 92.04%,the supernatant transparency was up to 98.6% and the flocculation time was 9 s,at room temperature and copolymer dosage of 12 mg/L and the oil removal rate of copolymer was 94.5%,under the conditions of 30 mg/L copolymer dosage,50℃ and 7 h. The flocculation-demulsification performance of self made polymer was superior to BQ-05、SP-169 and PAM、PDMC.
