Characterisation of ice and THF hydrate slurry crystal size distribution by microscopic observation method

Experimental determination of the energy optimum for the transport of floating particles in pipes

“…To represent the variety of crystal sizes [19,35] the powder was sieved. Sieves of 310/560/760/910 lm were used to select three size ranges.…”

“…The technology involved, studied for over 20 years, is now mature for industrial use [19,20]. Many studies have been conducted on ice slurry flow in tubes [21,22] and in sudden constrictions [23,24].…”

Microstructure Observations of Natural Gas Hydrate Occurrence in Porous Media Using Microfocus X-ray Computed Tomography

“…[1][2][3][4][5] The microscopic nucleation and formation kinetics of natural gas hydrates in a porous media are of importance to the effective utilization of the huge resources. [6][7][8][9] There are four models for the formation of natural gas hydrates within the pore spaces of hydrate-bearing sediments: floating, supporting, coating, and cementing. 10,11 The occurrence model and the microstructure of natural gas hydrates within the pores directly govern the mechanical behavior of the sediments, incorporating aspects of solid deformation, multiphase flow, and phase transformation.…”

Multi-analytical approach for monitoring the freezing process of a milkshake based product

“…As they require only a cold room and refined image analysis, these methods are rapid, inexpensive, sufficiently accurate and easier to use by industrial operators compared with more sophisticated cryo-scanning electron microscopy and confocal laser scanning microscopy (Chang and Hartel, 2002b). Optical microscopy, in turn, could be replaced by more inexpensive and simple devices such as CCD microscopes (Delahaye et al, 2010).…”
