Carter, Donald R. (Texas A&M University. Turbomachinery Laboratories, 1988)Maintenance and operation of high pressure seal oil systems on centrifugal compressors has been a major problem faced by refinery operators. This problem is intensified when sealing gases like hydrogen and mixtures of ...
-
Shah, Piyush (Texas A&M University. Turbomachinery Laboratories, 1988)Dry gas seals can eliminate some of the conventional problems associated with seal oil systems. Increased safety, lowered maintenance and improved reliability are key considerations for retrofitting with gas seals. ...
-
Franks, Peter P.; Eads, Ben (Texas A&M University. Turbomachinery Laboratories, 1988)Emergency repairs of a cracked steam turbine disc can be accomplished effectively by using sound basic engineering principles. One such method used to expedite a repair is reported.
-
Unsal, Refah; Boyce, Meherwan P. (Texas A&M University. Turbomachinery Laboratories, 1988)A total online condition monitoring system has been in operation on the world's largest offshore facility located off the coast of Norway. The Ekofisk platforms are operated by the Phillips Petroleum Company Norway and ...
-
Lytwyn, Peter (Texas A&M University. Turbomachinery Laboratories, 1988)The basic types of seal face lubrication are described and the basic design concepts and deflection analysis are discussed. Present field installations are presented, along with operating conditions and common problems ...
-
Nissler, Karl H. (Texas A&M University. Turbomachinery Laboratories, 1988)Retrofits on compressors can become attractive if the operating requirements of a plant change. Often, compressor modifications are imposed by process changes due to market demands or new process technologies. Sometimes, ...
-
Atkins, Kenneth E.; Perez, Robert X. (Texas A&M University. Turbomachinery Laboratories, 1988)A gas seal retrofit project for a 2800 hp, 10200 rpm, five-stage hydrogen recycle compressor is described. This barrel-type compressor operates with a 1205 psia suction pressure and 1490 psia discharge pressure. The unit ...
-
Miller, William H. (Texas A&M University. Turbomachinery Laboratories, 1988)The induction motor has been the work horse of industry for many years. It has achieved this position by virtue of its ruggedness, and relative low cost. Induction motors include the popular squirrel cage and the versatile ...
-
Gupton, Paul S. (Texas A&M University. Turbomachinery Laboratories, 1988)Nondestructive evaluation is becoming increasingly important in determining the quality of materials and fabrications used in the manufacture and maintenance of rotating machinery. NDE has long been used as a tool for ...
-
Lovejoy, Kim A. (Texas A&M University. Turbomachinery Laboratories, 1988)Has the industrial standardization of the IBM PC/ AT as a building block for dedicated instrument computer systems brought costs down to the point where sophisticated monitoring systems are not only possible, but make good ...
-
Williams, Steve; Brandon, Ronald (Texas A&M University. Turbomachinery Laboratories, 1988)The losses in turbine performance due to excessive leakages in the labyrinth seals can result in significant heat rate degradation to the turbine cycle. The modified packing arrangement described helps eliminate the rubs ...
-
Singh, Marari P.; Vargo, John J.; Schiffer, Donald M.; Dello, James D. (Texas A&M University. Turbomachinery Laboratories, 1988)The complex field of turbine blade vibration has long been in need of improved tools to help predict the reliability of blading. The SAFE interference diagram is presented as such a tool. It presents much more information ...
-
Sandstede, Heiko; Reischl, Klaus; Leonhard, Martin L. (Texas A&M University. Turbomachinery Laboratories, 1988)Experience, theoretical and practical, investigations are presented on two radial flow high-speed turbines, which showed unacceptable high subsynchronous vibrations during operation onsite. The first example deals with a ...

-
Campbell, Margaret C. (Texas A&M University. Turbomachinery Laboratories, 1988)The need to protect a turbine generator from abnormal operating condidtions is a given. Power plant operational historical data indicate that malfunction of the turbine protection system (TPS) has been the initiator of ...
-
McCann, Donald R.; Jhansale, H. R.; Anderson, James L. (Texas A&M University. Turbomachinery Laboratories, 1988)The approach and methodology to life assessment/extension are described. Items considered are nondestructive testing, material testing, flaw sizing, stress analysis, fracture mechanics analysis and cumulative damage analysis. ...
-
Leader, Malcolm E. (Texas A&M University. Turbomachinery Laboratories, 1988)All machinery vibrates, has heat generated internally, and begins to wear as soon as it is put into service. The monitoring process must be customized for each class of equipment. If possible, each machine should be evaluated ...
-
Adams, Mark A.; Bloch, Heinz P. (Texas A&M University. Turbomachinery Laboratories, 1988)The lube oils in self-contained reservoirs for turbomachinery in hydrocarbon processing plants are subject to contamination and deterioration from airborne dust, component debris, system corrosion, heat, and water. Oil ...
-
Coleman, William L. (Texas A&M University. Turbomachinery Laboratories, 1988)Ever since steam turbines have been built, contamination of the lube oil by water has been a persistent problem. Water contamination will result in rusting of ferrous components, accelerate sludging leading to sticking of ...
