Study of Enhancement of Synthesis of Freon 134a Gas Hydrate During Boiling of Liquefied Gas with Its Simultaneous Stirring with Water

Abstract

The paper presents an analysis of the dependence on gas hydrate synthesis on the initial mass of hydrate-forming gas in a method based on explosive boiling of liquefied hydrate-forming gas in a volume of water. An experimental study for two cases is presented: with and without stirring of the working area during decompression. Freon 134a was used as a hydrate-forming gas.

Study of the formation of carbon dioxide hydrate in a colloidal solution of water + SDS + SiO2 at a constant SiO2 concentration of 500 ppm

“…Currently, research is focused on studying the physicochemical properties and thermodynamic conditions that are necessary for the formation of hydrates using various promoters [4][5][6][7]. Experts also study both the synthesis of gas hydrates under various conditions and their decomposition, assessing thermal and convective processes [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Influence of SDS concentration on the formation of carbon dioxide hydrate in a colloidal solution of water + SDS + SiO2

“…Although hydrate formation has many useful properties, the technology for industrial application of this process does not yet exist due to its complexity. At present, studies are underway on the physicochemical properties and thermodynamic conditions for the formation of hydrates with the addition of various promoters [4][5][6][7][8][9][10]. In addition, specialists study the synthesis of gas hydrates under different conditions and their dissociation during combustion, as well as evaluate thermal and convective processes [11][12][13][14][15][16][17][18][19][20].…”

Effect of SDS concentration on the process of hydrate formation by explosive boiling of liquefied freon 134a in water with SDS volume

“…Studies of the physicochemical properties and thermodynamic conditions for the formation of hydrates are carried out to develop production technologies [6][7][8][9][10][11][12][13][14][15][16][17]. Specialists also study the synthesis of gas hydrates under different conditions and their dissociation during combustion, analyze thermal and convective processes [18][19][20][21][22][23]. However, the existing methods for producing gas hydrates have disadvantages, which include low efficiency and productivity, therefore, a team of authors developed a new method based on the explosive boiling of liquefied hydrate-forming gas in a volume of water during decompression, which combines several factors, such as the introduction of a large volume of gas in a liquefied state, mixing, cooling and removal of the generated heat [24][25][26].…”
