Wallen, Paul J.; Towsley, Gregory S. (Texas A&M University. Turbomachinery Laboratories, 1999)In adding a second urea plant in 1974 at a Midwestern nitrogen plant, higher cooling water requirements necessitated the construction of an additional cooling tower. A 130 million Btu/hour cooling tower was installed with ...
-
Free, D. Waylon; Tullis, Blake P.; Bird, James R. (Texas A&M University. Turbomachinery Laboratories, 1999)The status of our country’s infrastructure is a topic that has been discussed at length in the past few years. Aging roads and bridges are no longer capable of meeting the demands of a growing population. They suffer either ...
-
Prouty, Warren C.; Da Silva, Derek S.; Farrell, Harry (Texas A&M University. Turbomachinery Laboratories, 1999)A unique hydrostatic throttle bushing concept has been developed and successfully tested. The throttle bushing is based on the concept of typical hydrostatic face seals, but incorporates improvements to minimize cavitation ...

Harris, Mark A.; Paddock, Douglas; Voelkel, Joseph O.; Szymanski, Kenneth D. (Texas A&M University. Turbomachinery Laboratories, 1999)Balancing of pump rotating components, especially impellers, is common practice. The purpose of this effort was to determine the proper design of pump components and balance arbors, create appropriate procedures, and ...
-
Cooper, Mark; Parker, Joseph C. (Texas A&M University. Turbomachinery Laboratories, 1999)A major producer of ethylene installed and is successfully operating a nonpressurized dual gas seal in liquid methane service. The least reliable pump in the unit was a single stage overhung centrifugal pump in demethanizer ...
-
Wu, Shifeng; Kowalski, Christopher A.; Stafford, Lynn E. (Texas A&M University. Turbomachinery Laboratories, 1999)In this paper, an innovative approach of applying gas-lubricated, noncontacting sealing technology to process pumps is presented, in which a novel “twin hybrid” design is incorporated to address the issues of gas seal ...
-
Lebeck, Alan O.; Albor, Gabriel (Texas A&M University. Turbomachinery Laboratories, 1999)There has been a rapid growth in the application of noncontacting double seals with a gas buffer fluid to pump sealing. The advantages of such a sealing arrangement are: • There is no liquid buffer fluid to maintain or ...
-
Crook, Clay (Texas A&M University. Turbomachinery Laboratories, 1999)A Gulf Coast refinery decided to actively address rising pump maintenance costs and risk of production losses by using accumulated failure data and maintenance costs to identify bad actor pumps, then solving the problems ...
-
Kaiser, Roland; Lienau, Wolfram; Peters, Douglas J. (Texas A&M University. Turbomachinery Laboratories, 1999)Often the industrial power generation market specifies that boiler feedpumps must be capable of withstanding thermal transient conditions when operating in boiler feed service. A thermal transient analysis was performed ...

Schlucker, Eberhard; Blanding, James M.; Murray, Joseph F. (Texas A&M University. Turbomachinery Laboratories, 1999)
-
Klostermann, Gregory E. (Texas A&M University. Turbomachinery Laboratories, 1999)Since the introduction of noncontacting, gas lubricated, dual pressurized mechanical seals for process pumps over five years ago, and they have primarily been applied to ANSI pumps and other applications where the barrier ...
-
Silvaggio, Joseph A.; Krafft, Gary (Texas A&M University. Turbomachinery Laboratories, 1999)Six topics that should extend the life of a boiler feedpump will be described in detail. These topics will explore both operational and maintenance techniques that, when instituted, have been shown to extend the useful ...
-
Barringer, H. Paul; Monroe, Todd R. (Texas A&M University. Turbomachinery Laboratories, 1999)For the typical machinery engineer, the difficulties encountered with making reliability improvements lie not with the “mechanics” of improvements, but with justifying the cost of improvements. It is difficult to translate ...
-
Parris, Mark; Cameron, Dan (Texas A&M University. Turbomachinery Laboratories, 1999)At most industrial facilities, the engineering, maintenance, and operation groups are under great pressure to increase reliability and also reduce costs. This paper discusses the role of operators in achieving low cost ...
-
Claxton, Jack; Hecker, George E.; Sdano, Arnold (Texas A&M University. Turbomachinery Laboratories, 1999)A balanced committee of users, designers, researchers, and pump manufacturers has produced a revised Hydraulic Institute Pump Intake Design Standard that is considerably different from the existing standard and more ...
-
Hinkel, Tommy; Giffrow, Matt (Texas A&M University. Turbomachinery Laboratories, 1999)At a major oil products refinery, an aggressive effort has been ongoing to improve centrifugal pump reliability and efficiency. Working closely with a manufacturer of high-grade thermoplastics, the company has developed ...
-
Selection Of Lube Oil Systems Components For Process Pumps And Auxiliaries (External, Pressurized) Patel, Vinod; Coppins, Don (Texas A&M University. Turbomachinery Laboratories, 1999)Lube oil systems are utilized in rotating process equipment to lubricate and cool hydrodynamic bearings. These systems are essential to the life and maintenance free operation of the process equipment. Dependable performance ...
