摘要： A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding a reaction product to the mixtures in an effective amount to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the reaction product. The product is made by the reaction of first reactant that is an amine or polyamine, or alcohol or polyalcohol, with a second, aldehyde reactant and a third reactant that is an alcohol or polyalcohol or, an amide or polyamide. Preferably, if the first and third reactants are both an alcohol or both a polyalcohol, they are not the same. A non-limiting example of a suitable amine would be a fatty alkyl amine, while formaldehyde would be a non-limiting of a suitable aldehyde and polyacrylamide would be a suitable third reactant.

摘要： Gas hydrates, particularly natural gas hydrates e.g. methane hydrates, may be formed and controlled within conduits and vessels by imparting energy to gas and water, for instance using agitation or vibration. The systems and methods allow for improved flow characteristics for fluids containing the gases, e.g. hydrocarbon fluids being transported, and for improved overall efficiencies. The gas and water within a gas flow path may be perturbed or agitated to initiate formation of relatively small hydrate particles. The hydrate particles continue to form as long as energy is imparted and water and hydrate guest molecules are available. High amplitude agitation of the gas and water will repeatedly break up agglomerated hydrate particles that form and encourage the formation of more and smaller particles. As more hydrate forms in this manner, less and less free water may be available proximate the gas and water contact.

摘要： A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule has been discovered that involves adding a composition to the mixtures in an amount that is effective in inhibiting formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the reaction product. The composition includes at least one dendrimeric compound having a number average molecular weight of at least 1,000 atomic mass units (amu); and at least one small molecular weight species having less than 1,000 amu, selected from the group consisting of polyalkyleneimine, polyallylamine, starch, sugars, and polymers or copolymers of vinyl alcohol or allyl alcohol; and, optionally, at least one surfactant.

摘要： A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding an ion pair to the mixtures in an amount effective to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the ion pair. In one non-limiting embodiment of the invention the ion pair includes a cationic component that may be a quaternary ammonium compound or an onium compound and a non-cationic counter-ion component that could be an anionic compound, a non-ionic compound and/or an amphoteric compound. Two specific, suitable non-cationic counter-ion components include sodium dodecyl sulfate and ammonium alkyl ether sulfate.
