Definition of the induction time for CO₂ and CH₄ hydrate via evaluation of the heat released during the process and the gas consumption rate.

Abstract The induction period is defined as the time required to obtain a detectable quantity of hydrates during their natural or artificial production. This includes initial nucleation phase and part following massive growth phase. Several methods were thought measure its length: most adopted are visual observation process direct temperature increase. However, these techniques not always feasible accuracy often low. work deals with definition by considering heat produced process, which proportional but significantly less affected stochastic nature process. In order prove feasibility results then compared what obtained gas consumption rate time. proposed method was validated for methane hydrates. same confirmation possible carbon dioxide hydrates, due high solubility in water this species consequent overestimation
