摘要： The inhibiting or retarding hydrate formation, growth and/or agglomeration in a fluid comprising water and gases, is accomplished by addition of at least one hydrosoluble homopolymer or copolymer derived from at least one nitrogen-containing monomer selected from cationic monomers, for example those containing at least one quaternary ammonium moiety, amphoteric monomers, for example those containing at least one quaternary ammonium moiety and at least one carboxylate or sulphonate moiety, and various neutral monomers, said hydrosoluble homopolymer or copolymer being neutral or anionic, or consisting of a polyampholyte. The homopolymer, copolymer or mixture of polymers optionally mixed with an alcohol is generally incorporated into the fluid to be treated at a concentration of 0.05% to 5% by weight with respect to the quantity of water in the medium.

摘要： The invention concerns a process for reducing the tendency of hydrates in a fluid comprising at least water, a gas and a paraffin oil to agglomerate, by addition of a mixture of at least two organosoluble additives, namely at least one polyisobutene-polyethyleneglycol block copolymer and at least one copolymer of an alkyl (meth)acrylate and a nitrogen-containing monomer. These organosoluble copolymers are generally introduced at an overall concentration of 0.05% to 5% by weight with respect to the water present in the medium.

摘要： A description is given of a process for reducing the agglomeration tendency of hydrates within a fluid incorporating at least water and hydrocarbons, liable to form hydrates, under conditions where said hydrates may form, characterized in that into said fluid is incorporated an alkylene oxide-based hydrosoluble polymer or copolymer containing at least one --(OR)--.sub.n sequence, in which R represents a hydrocarbon group having 2 or 3 carbon atoms and n represents the average degree of polymerization of said sequence, at least one of the --(OR)--.sub.n sequences being an ethylene polyoxide sequence, associated with a thermodynamic inhibitor of the formation of hydrates, e.g. an alcohol or a glycol. This process is particularly appropriate for the case where the fluid to be treated contains a high proportion of water, e.g. more than 30% by weight. The presence of salts in the water can at least partly dispense with the addition of alcohols or glycols.

摘要： New dispersing additive compositions for lubricating oils, an object of the invention, have an improved efficiency.Said compositions may be either (1) the products obtained by reacting alkenylsuccinimides with aromatic dianhydrides, or (2) the products obtained by reacting alkenylsuccinimides with an anhydride or a dianhydride of mono- or poly-carboxylic aliphatic, alicyclic or aromatic acid of low molecular weight, the obtained product being then reacted with at least one organic compound having several hydroxyl and/or amine groups.These dispersing additive compositions may be added to lubricating oils in a proportion, for example, from 0.1 to 20% by weight.
