Preparation and Evaluation of Terpolymer Methane Hydrate Kinetic Inhibitors
摘要
Abstract
P(NVP/MAH/AM)and P(NVP/MAH/MAA)which were kinetic inhibitors with terpoly-mer were synthetized using N-vinyl pyrrolidone,maleic anhydride,acrylamide andα-methacrylic aci-dand were characterized by FT-IR and GPC.The effects of inhibitor mass fraction,initial pressure and undercooling were researched for the formation process of CH4 hydrate.The compound performance of kinetic inhibitors was also evaluated.The results showed that induction time increase significantly along with inhibitor mass fraction increasing,but CH4 consumption was not changed.The inhibition a-bility of P (NVP/MAH/AM)was better than P (NVP/MAH/MAA),and the induction time was 245min for P(NVP/MAH/AM)aqueous solution with mass fraction of 1.5×10-3.The inhibiting properties can be further improved after the combination of kinetic inhibitors and thermodynamic in-hibitors.When P(NVP/MAH/AM)aqueous solution with mass fraction of 1.5×10-3 was mixed with glycol aqueous solution with mass fraction of 1.0×10-1 ,the induction time was 900min.关键词
