The study investigates chemical control of hydrates in pipeline by the application of different chemical substances such as methanol, ethylene glycol, diethylene glycol and triethylene glycol. Aspen Hysys simulator was used to determine hydrate formation temperature based on gas field composition and operating pressure by using Peng-Robinson equation. Similar simulations were carried out with the injection of chemical inhibitors such as methanol, ethylene glycol, diethylne glycol and triethylene glycol. The chemical inhibitors prevents hydrate formation by reducing hydrate formation temperature, thereby mitigating against hydrate formation and ensuring constant flow and production of fluid with methanol been the most effective chemical inhibitor based on the hydrate formation temperature reduction trends and analysis.
