Study on the kinetics of hydrate formation in a bubble column

Modelling of hydrate formation kinetics: State-of-the-art and future directions

“…An empirical exponential relationship between the specific gas consumption rate and this driving force was proposed to represent the data, containing two system-dependent parameters to be fitted. Although limited to the operating conditions investigated by the authors in view of the empirical nature of its final rate equation, the model of Luo et al (2007) represents the first attempt to model hydrate formation in a bubble column reactor. It is important to highlight that, together with spray reactors, bubble columns have drawn considerable attention regarding hydrate formation for the storage of natural gas (Williams and Smith, 1997;Matsumoto, 2001;Koda and Okui, 2001;Takeshi, 2004;Koji and Takeshi, 2004).…”

“…Nonetheless, on account of its two parameters, the model still provided a suitable representation of the experimental data obtained by Clausse et al (2003) in a differential scanning calorimeter. Luo-Zhu-Fan-Chen Luo et al (2007) studied the formation of methane hydrate in the presence of THF as a promoter in a 2.54 cm-in-diameter bubble column reactor and developed a kinetic model to represent their data. With the aid of literature correlations, the authors estimated the total interfacial area in the reactor for each operating condition and then expressed their results as the specific methane consumption rate per unit gas-liquid interfacial area.…”

Enhanced clathrate hydrate formation kinetics at near ambient temperatures and moderate pressures: Application to natural gas storage

“…To overcome the slow kinetics, continuous research efforts have been put forth in improving the kinetics of methane hydrate formation either by innovative reactor designs [14][15][16][17][18][19][20] including the use of different porous media [21][22][23][24][25][26][27][28][29] or the use of kinetic promoters (predominantly surfactants) in order to enhance the rate of hydrate formation [30][31][32][33][34][35]. Though the kinetics of hydrate formation is improved by a choice of suitable reactor or kinetic promoter, there is no reduction of the high energy requirement due to low temperature and high pressure conditions of hydrate formation.…”

“…However, on an industrial scale, this formation path seems to be disadvantageous due to its low formation rate. This also applies to bubble columns, as for the required technical scales, liquid phase gas dispersion and thus the achievable interfacial areas are limited [28]. From the literature, it can be concluded that continuously stirred tank reactors (CSTRs), static mixers and spray reactors show sufficiently good hydrate formation rates for the proposed process [29,30].…”
