“…A high‐pressure hydrate slurry rheological measurement system (Figure ) was used, which included a multiphase mixture preparation system, a rheological measurement system, and a temperature control system. The multiphase mixture preparation system is used to prepare the natural gas hydrate slurry containing wax crystals, which is composed of a high‐pressure gas cylinder, a gas pressurization device, and a high‐pressure autoclave reactor.…”

“…For the rheological studies of hydrate slurry, Hagen‐Poiseuille equation and Rabinowitsh‐Mooney equation were widely used to calculate hydrate slurry viscosity indirectly, based on the experimental data measured by different high‐pressure flow loops . Also, many different high‐pressure rheometers were employed to measure the gas hydrate slurry viscosity directly . According to the published literature, two significant conclusions have been obtained.…”

“…And, a bimodal model was developed to predict the viscosity of multiphase mixing transportation systems containing hydrates, by combining two single peak models . Based on the Einstein effective medium theory for water‐in‐oil emulsion systems, a natural gas hydrate slurry viscosity model was developed using non‐Newtonian coefficients, which considered the aggregation and breakage of hydrate particles …”

Clarifying the interaction effect between hydrate and wax is of great significance to guarantee operation safety in deep water petroleum fields. Experiments in a high-pressure hydrate slurry rheological measurement system were carried out to investigate hydrate formation and slurry viscosity in the presence of wax crystals. Results indicate that the presence of wax crystals can prolong hydrate nucleation induction time, and its influence on hydrate growth depends on multiple factors. Higher stirring rate can obviously promote hydrate growth rate, while its influence on hydrate nucleation induction time is complicated. Higher initial pressure will promote hydrate formation. Gas hydrate slurry shows a shearthinning behavior, and slurry viscosity increases with the increase of wax content and initial pressure. A semiempirical viscosity model showing a well-fitting is established for hydrate slurry with wax crystals by considering the aggregation and breakage of hydrate particles, wax crystals, and water droplets.

“…These studies are mainly divided into two groups: one group consists of fundamental research and the other group consists of applied background research. In fundamental studies, natural gas hydrates are synthesized in gas and liquid reaction systems when the conditions of the reactants or mediums are gases of different compositions [5], liquids of different compositions [6][7][8], and different combinations of liquid-solid systems [9,10]. In applied background studies, natural gas hydrate formations and process are evaluated in reactors of varying scales and types [11][12][13][14][15].…”

Abstract1L spraying reactor with a heat exchanger outside was used to investigate the effect of spraying hydration process on storage capacity of methane in hydrate and on a methane storage rate in hydrate to solve a problem of lower gas molecular transfer rate and worse heat transfer rate. Some results showed that ethanol as a promoter had better spraying hydration rate under the liquid spraying pressure 4-5 MPa, 0.46V g V H -1 min -1 , which had been approximately 10 times when conventional additive, sodium dodecyl sulfate, was added to reaction system. Others showed that the spraying hydration reactor in advantage had lain in achieving higher hydration rate at lower operational pressure of gas phase compared with semi-continuous stirred tank reactor. Furthermore, evaluation investigation on spraying hydration reaction showed that energy consumption had been 0.41kJ, while methane hydrates containing 1kJ heat were produced, and that the capital efficiency in economy for the hydration process had been 0.41 under perfect competition. Finally, the process evaluation parameter used had become a measure instrument for the prospect of resource utilization efficiency or for venture forecasting of capital investment.
