Because of availability, as well as economical and environmental considerations, natural gas is projected to be the premium fuel of the 21st century. Natural gas production involves risk of the shut down of onshore and offshore operations because of blockage from hydrates formed from coproduced water and hydrate-forming species in natural gas. Industry practice has been usage of thermodynamic i...

Slag is increasingly unitized for the production of sustainable concrete. This paper presents a procedure with which to analyze property development slag composite Experimental studies hydration heat and compressive strength simulation using kinetic model thermodynamic were performed. First, we performed an experimental study isothermal cement–slag blends. Based on results cumulative heat, reac...

We are focusing on the practical use of methane hydrate. For recovery and it as an energy resource, is necessary to consider possibility clogging in pipe due rehydration bubbles. The purpose this research was observe experimentally evaluate theoretically decomposition behavior hydrate sedimentary layer rising bubbles generated by decomposition. Chlorodifluoromethane used a low pressure model ga...

We report the first UV-vis spectroscopic study of bromine molecules confined in clathrate hydrate cages. Bromine in its natural hydrate occupies 51262 and 51263 lattice cavities. Bromine also can be encapsulated into the larger 51264 cages of a type II hydrate formed mainly from tetrahydrofuran or dichloromethane and water. The visible spectra of the enclathrated halogen molecule retain the spe...

This study explores the process of methane hydrate formation and dissociation in a small-scale confined environment presence porous sediment. The research is focused on answering shortage information about intrinsic properties processes, such as memory effect anomalous self-preservation, lab-scale apparatus. Experiments were carried out consecutively with same gas–water mixture. temperature rea...

We investigate the relationship between the mixing times of the Glauber dynamics of a statistical mechanical system with its thermodynamic equilibrium structure. For this we consider the mean-field Blume-Capel model, one of the simplest statistical mechanical models that exhibits the following intricate phase transition structure: within a two dimensional parameter space there exists a curve at...
