摘要： Latex drag reducers and systems for delivering latex drag reducers are disclosed. The latex drag reducers comprise a polymer that is formed via an emulsion polymerization reaction dispersed in a continuous phase and can undergo subsequent modification in order to increase the solubility of the polymer in hydrocarbons. The polymers generally present a particle size of less than about 1000 nm and are suitable for delivery to a subsea flowline via a small diameter conduit of an umbilical line without an unacceptable level of pressure drop or plugging of the conduit.

摘要： A modified latex drag reducer and methods of making and using the drag reducer in order to reduce friction losses resulting from turbulent fluid flow through a conduit. Particularly, the modified latex drag reducer is formed from an initial latex which is a product of an emulsion polymerization reaction. The initial latex is then modified, preferably by admixing with at least one low HLB surfactant or at least one solvent, or both, to form a modified latex with an enhanced dissolution rate in a hydrocarbon stream over the initial latex.

摘要： A system for reducing pressure drop associated with turbulent fluid flow through conduits located in remote locations (e.g., deep under ground and/or deep under sea). Such reduction in pressure drop is accomplished by transporting a drag reducer through a long conduit of small diameter and thereafter injecting the drag reducer into a host fluid at the remote location, to make a treated fluid. The treated fluid is then extracted from the remote location via a production/transportation conduit. The presence of the drag reducer in the treated fluid reduces pressure drop associated with flow through the production/transportation conduit.
