摘要:

提出了一种天然气水合物低剂量组合抑制剂GHI,GHI是聚乙烯吡咯烷酮(PVPK90)/乙二醇苯醚按质量比1∶1混合而成。在4℃,8.5~9.0MPa条件下,利用1.072L定容反应釜,通过观察温度和压力的变化,研究了GHI在0.5%加量下的抑制性能,并在此加量下与PVPK90及商用抑制剂Inhibex100、Inhibex501的抑制效果及经济性进行了比较。研究结果表明:加量为0.5%的GHI可以有效地抑制天然气水合物聚集2400min以上;在相同的实验条件下,Inhibex100、Inhibex501和PVPK90的抑制时间分别为1000min,1800min和600min;经济性评价说明GHI相对于商用抑制剂Inhibex501和Inhibex100是最经济的,它比Inhibex501价格低22.5%,比Inhibex100价格低34.7%。

Abstract: A new low dosage hydrate inhibitor GHI is proposed,which is composed of polyvinlypyrrolidone(PVDK90) and ethylene glycol monophenyl ether with a 1∶1 ratio.Through changes of temperature and pressure,the inhibition of GHI is investigated and compared with polyvinlypyrrolidone and commercial inhibitors Inhibex100,Inhibex501 at 4℃ and 8.5~9.0MPa in a 1.027 liter reactor.The commercial price is also compared.The results show 0.5% GHI can inhibit gas hydrate agglomeration for more than 2400min,under the same condition,the inhibition time for Inhibex100,Inhibex501 and PVDK90 are 1000min,1800min and 600min respectively.The commercial price of the GHI is 22.5 percent lower than that of Inhibex501 and 34.7 percent lower than Inhibex100.
