【摘要】：針對(duì)現(xiàn)有水合物動(dòng)力學(xué)抑制劑存在的缺點(diǎn),以N-乙烯基吡咯烷酮為單體,雙氧水為引發(fā)劑,在氮?dú)庾饔孟?采用溶液聚合法合成了一種動(dòng)力學(xué)抑制劑,利用實(shí)驗(yàn)室水合物動(dòng)力學(xué)實(shí)驗(yàn)裝置,考察了抑制劑的添加量、過(guò)冷度等因素對(duì)抑制劑性能的影響,研究了新型動(dòng)力學(xué)抑制劑與乙二醇復(fù)配的復(fù)合型抑制劑的性能。實(shí)驗(yàn)結(jié)果表明,抑制劑添加量為1 500 mg/L時(shí),在5℃、6 MPa條件下的誘導(dǎo)時(shí)間達(dá)213 min,抑制劑溶液在過(guò)冷度為9.1℃時(shí)的誘導(dǎo)時(shí)間達(dá)59 min;10 000 mg/L動(dòng)力學(xué)抑制劑與15%(w)的乙二醇進(jìn)行復(fù)配,所得復(fù)合型抑制劑的誘導(dǎo)時(shí)間比單獨(dú)使用動(dòng)力學(xué)抑制劑的誘導(dǎo)時(shí)間延長(zhǎng)了234.0%,具有良好的復(fù)配效果。
[Abstract]:In view of the shortcomings of the existing hydrate kinetic inhibitors, a kinetic inhibitor was synthesized by solution polymerization with N- vinyl pyrrolidone as monomer and hydrogen peroxide as initiator under the action of nitrogen. The effects of the amount of inhibitor and the degree of undercooling on the performance of the inhibitor were investigated by using the experimental apparatus of hydrate kinetics in laboratory. The performance of a new type of complex inhibitor with ethylene glycol and kinetic inhibitor was studied. The experimental results showed that when the amount of inhibitor was 1 500 mg/L, At 5 鈩，
