To address the challenges associated with gas hydrate formation in deepwater environments, two novel waterborne polyurethanes were developed using etidronic acid (EA-WPU) and citric (CA-WPU) as kinetic inhibitors. EA-WPU exhibited superior inhibition, completely preventing sII at a concentration of 0.5 wt %. CA-WPU also showed strong performance, subcooling temperature (ΔT) values 13.16 11.62 °C concentrations 0.25 %, respectively. These polymers have demonstrated high efficiency inhibiting formation, even low (0.05 %). The inhibition performance against sI hydrates varied, Luvicap EG demonstrating strongest inhibitory effects. At ΔT value 6.05 °C, comparable to that EG. This study suggests specific functional groups present end-cap structure WPUs directly influence their ability inhibit hydrates. Carboxylic phosphonate appear be more effective for hydrates, Moreover, field-specific assessments % achieved 15.5 surpassing required 12 prevent 280 bar 15 °C. allowed 90-fold reduction inhibitor consumption compared 23 methanol solution. Additionally, solutions remained transparent no clouding up 70 2 1 Although occurred higher temperatures, both stable without deposition 8 results highlight excellent thermal stability CA-WPU, making them suitable high-temperature injection Good make promising candidates widespread application management, offering significant operational cost savings reduced environmental impact.
