摘要
合成了新型动力学天然气水合物抑制剂DVP,以四氢呋喃法(THF)对其性能进行了评价。DVP的最佳合成条件为:n(N-乙烯己内酰胺)∶n(丙烯醇)∶n(甲基丙烯酸羟乙酯)=5∶1∶1,引发剂加量为0.5%(占单体质量百分数),反应温度60℃,反应时间8 h。DVP的加量0.5%,抑制效果最好,水合物结冰温度为-8℃。结合天然气水合物抑制剂PVP做性能对比,DVP具有加量少、抑制效果好的优点。将DVP与热力学水合物抑制剂进行复配,DVP的抑制性能得到进一步提高。
A new kinetic of natural gas hydrate inhibitor DVP is independent synthetic equipment using self-designed evaluation,by the method of four hydrogen barking dogs（ THF） on its performance is evaluated. The DVP optimal synthetic conditions were determined as follows： n（ N-vinyl caprolactam） ∶ n（ propylene glycol） ∶ n（ hydroxyl ethyl methacrylate） = 5∶ 1∶ 1,amount of initiator added was 0. 5%（ mass percent） of monomer,reaction temperature 60 ℃,the reaction time of 8 h. The DVP added value of 0. 5%,hydrate freezed temperature is 8 ℃. Performance compared with gas hydrate inhibitor PVP,DVP added quantity is little,inhibit the advantages with good effect. Finally,the DVP distribution with thermodynamic hydrate inhibitors,DVP suppression performance is further improved.
