PAC-P(AM-BA)杂化高分子絮凝剂制备及絮凝效能评价
Preparation and flocculation efficiency evaluation of a PAC-P(AM-BA)hybrid polymer flocculant
摘要
Abstract
In order to solve the problem of chemically driven sewage in oil fields,a new inorganic-organic hybrid polymeric flocculant(PAC-P(AM-BA))was synthesized by aqueous free radical micelle polymerization with polymerized aluminum chloride(PAC)as the inorganic component and acrylamide(AM)and butyl acrylate(BA)as organic monomers.The flocculants were characterized using Fourier transform infrared spectroscopy(FT-IR),thermogravimetric analyzer(TGA),scanning electron microscopy(SEM),and specific surface area analyzer(BET).The results show that BA is chemically bonded in the long chain of polyacrylamide(PAM),and the inorganic component is ionically bonded to the organic component.The thermal decomposition temperature of PAC-P(AM-BA)was 233.93℃,and the specific surface area was 30.351 m2·g-1.The flocculation results show that the optimum dosage of PAC-P(AM-BA)is 20 mg·L-1,the settling time is 10 h,and its floc fractal dimension is 1.733.In the flocculation efficiency comparison experiment,the average oil removal rate of PAC-P(AM-BA)is 90.3%,which is 16.4%and 29.0%higher than that of cationic polyacrylamide(CPAM)and compound flocculant(PAC+PAM),respectively.关键词
