Patent number: 9828918Abstract: An apparatus and method for protecting an inner radial surface of a radial member of a turbomachine from corrosion are provided. The method may include shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner. The method may also include heating the radial member to increase a diameter of the inner radial surface of the radial member, and inserting at least a portion of the corrosion-resistant liner into the radial member. The method may further include attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.Type: GrantFiled: October 29, 2013Date of Patent: November 28, 2017Assignee: Dresser-Rand CompanyInventors: Byron L. Mohr, David C. Seib

Patent number: 9249887Abstract: A seal assembly for use in a turbomachine is provided. The seal assembly has an annular division wall with outside and inside surfaces, a carrier ring disposed adjacent the inside surface of the annular division wall, and a sealing substrate metallurgically-bonded to an inner-most surface of the carrier ring. The sealing substrate is machined to form a seal surface that can be disposed proximate a rotor and maintained substantially parallel thereto during operation of the turbomachine.Type: GrantFiled: August 3, 2010Date of Patent: February 2, 2016Assignee: Dresser-Rand CompanyInventors: David C. Seib, Mark Joseph Kuzdzal

Patent number: 8596413Abstract: The invention is an acoustic liner for attenuating noise in rotating machinery. The acoustic liner may include a plurality of cells coupled together to form an annular cell matrix, the plurality of cells being made of a non-metallic material, for example, plastics, polymers, thermoplastics, or thermosets. Each cell of the acoustic liner may be hexagonally-shaped such that the annular cell matrix forms a honeycomb structure.Type: GrantFiled: July 9, 2012Date of Patent: December 3, 2013Assignee: Dresser-Rand CompanyInventor: David C. Seib

Patent number: 8585977Abstract: A method and system for reducing corrosion in a turbomachine are provided. The method may include providing a process gas to a condenser, wherein the process gas contains a condensate having a pH level that is acidic. The condenser may be configured to remove at least a portion of the condensate from the process gas. Any condensate that is not removed is a remaining condensate. The method may further include increasing the pH level of the remaining condensate to above about 4 by mixing the process gas and the remaining condensate with an amount of pH modifier to form a mixture, and directing the mixture to a compressor coupled to the condenser, wherein the compressor is configured to compress the mixture.Type: GrantFiled: December 21, 2011Date of Patent: November 19, 2013Assignee: Dresser-Rand CompanyInventors: Robert R. Odle, David C. Seib

Patent number: 8075245Abstract: Embodiments of the disclosure may provide an exemplary method for operating a compressor system, wherein the method may include cooling a process gas containing water vapor to a first temperature. The water vapor may form a condensate at the first temperature, and cooling the process gas may produce residual heat. At least a portion of the condensate is removed from the process gas, wherein any portion of the condensate that is not removed is a remaining condensate. The remaining condensate may be heated to a second temperature with the residual heat, wherein the remaining condensate in the process gas evaporates at the second temperature.Type: GrantFiled: May 27, 2009Date of Patent: December 13, 2011Assignee: Dresser-Rand CompanyInventors: Robert R.

Patent number: 8061031Abstract: An impeller assembly is for a fluid machine, such as a compressor, and includes a first, main body and a second body. The main body includes a first section providing at least a substantial portion of either an impeller disc or an impeller cover and a second section spaced generally axially from the first section and providing a portion of the other one of the disc or the cover. A plurality of integrally formed blades extend between and connect the main body first and second sections such that the main body is generally of one piece construction. A plurality of flow channels are defined between the blades and a plurality of access openings extend into the flow channels. The second body provides a remainder of the disc or cover and is attachable to the main body to substantially form an impeller and to close all of the access openings.Type: GrantFiled: June 29, 2009Date of Patent: November 22, 2011Assignee: Dresser-Rand CompanyInventors: Andrew Jason Ranz, David C.
