Effect of molar ratio of counter-ions to surfactants treating trimethylolethane hydrate slurries.

Author(s) : SUZUKI H., TATEISHI S., KOMODA Y.

Summary

Experimental studies on flow characteristics and particle size distributions of trimethylolethane (TME) hydrate slurries treated with drag-reducing surfactants have been performed in order to investigate the effect of molar ratio of counter-ions to surfactants. As drag-reducing surfactants, oleylbishydroxyethylmethylammonium chloride was used. The molar ratio of counter-ions of sodium salicylate to surfactants was changed from 0 to 100 while the concentrations of TME in water and of surfactants were set constants at 25 wt% and at 2000 ppm. From the results, it was found that the drag reduction limitation is high and the particle size is rather small when the molar ratio of the counter-ions to surfactants is set at 50. From this, 50 of the molar ratio of counter-ions to surfactants is concluded to be the optimum on the drag reduction and on the particle size among the present experimental conditions.
