Abstract (en)
Method for transporting hydrates in suspension within a fluid comprising water, a gas and a liquid hydrocarbon (where hydrates can be formed starting from water and gas), comprises incorporating the fluid mixture containing component A of formed esters enters to a 8-24C monocarboxylic acid and 2-200C alcohol, and component B of non-ionic surface-active agents such as monocarboxylic polymerized unsaturated fatty acids.
