摘要:
VC-713是一种抑制能力强、应用成熟的水合物动力学抑制剂,其水合物抑制性及抑制机理一直是各国学者研究的热点.通过600 rpm和12 000 rpm的搅拌剪切作用促使加质量分数为0.5%的VC-713不同程度地溶解分散于溶液中,进而结合THF水合物形成模拟实验(实验条件为常压、温度由5.0 ℃逐渐降至0.5 ℃)、VC-713浓度变化监测实验及实时记录的反应釜内实验现象探明了不同剪切作用下各组VC-713水溶液的水合物抑制性,并对其内在影响机理进行分析.结果表明:VC-713可通过吸附、包裹作用抑制水合物成核及生长,且相对更好地溶解分散于溶液内的VC-713能够更为有效地抑制水合物的形成.
Abstract:
VC-713 is a strongly inhibitive,widely used hydrate kinetic inhibitor,its hydrate inhibition and inhibition mechanism are hot point questions all along.In this paper,VC-713 with the amount of 0.5wt% is dissolved and dispersed into the solutions at the different shearing action(the shear rate is 600 rpm and 12 000 rpm respectively),then the hydrate inhibition of VC-713 is discovered and its inherent inhibition mechanism is also analyzed by conducting simulation experiment on THF hydrate formation(normal pressure,temperature from 5.0 ℃ gradually down to 0.5 ℃),monitoring experiment of concentration variation of VC-713,and real-time recordings of experimental phenomenon.The results show that VC-713 inhibits hydrate nucleation and growth by the function of absorbing and wrapping effects,and the better dissolved and dispersed VC-713 can inhibit hydrate formation more effectively.
