The Thermodynamic and Kinetic Effects of Sodium Lignin Sulfonate on Ethylene Hydrate Formation

چکیده

Hydrate-based technologies (HBTs) have high potential in many fields. The industrial application of HBTs is limited by the low conversion rate water into hydrate (RWH), and sodium lignin sulfonate (SLS) has to solve above problem. In order make presence SLS applied industry promote advances commercial HBTs, effect on thermodynamic equilibrium formation pressure (Peq) was investigated for first time, a new model (which can predict Peq) proposed quantitatively describe formation. Then, effects initial concentration (rR) at different stages process were time reveal kinetic experimental results show that caused little negative Peq ethylene-SLS solution system predicted this work matches data well, with an average relative deviation 1.6% maximum 4.7%. increased RWH: final RWH from 57.6 ± higher than 70.0% using SLS, highest (77.0 2.1%) achieved when 0.1 mass%. rR did not significantly change as 35% 65% SLS. increasing decreased increase lower 30%, difference led 30%.
