摘要： In one aspect, the present invention provides a subsea separation vessel for the separation of a mixture comprising oil and water comprising (a) at least one inlet for introducing a oil-water mixture; (b) a flow path for conducting the oil-water mixture; (c) at least one oil-water separation structure; and (d) at least one fluid outlet. The oil-water separation structure includes a multifunctional surface. The oil-water separation structure is located within the flow path and wherein the multifunctional surface is superhydrophobic with respect to water, and either oleophilic or superoleophilic with respect to oil. A method for separating oil from an oil-water mixture is also provided.

摘要： In a gas turbine having a compressor discharge casing, a cooling circuit diverts compressor discharge air toward a high pressure packing (HPP) circuit. The cooling circuit includes an inlet pipe that receives compressor discharge air. One or several cooled cooling air pipes are in fluid communication with the inlet pipe via a pipe manifold, which distributes the discharge air across the cooled cooling air pipes. A seal is disposed upstream of an entrance to the HPP circuit to limit flow into the HPP circuit, and a second seal is disposed downstream of the HPP circuit at turbine wheelspace to limit ingestion and thus the purge flow air required. The circuit serves to reduce required purge flow in the HPP circuit so that an amount of compressor discharge air can be put back to the main flow path, thereby improving turbine performance.

摘要： An abradable seal is provided to improve turbine performance by physically reducing the clearance between a flange portion of the nozzle and an opposed angel wing/seal plate member of the bucket. The provision of an abradable seal also mitigates angel wing/seal plate tooth or fin wear by providing for abradable contact without metal to metal hard rub.
