-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Decarbonization of electric power infrastructure requires the development of cost-effective, sustainable, and reliable energy storage technologies that are capable of many Megawatts or Gigawatts of output and long storage ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Lubricating oil systems are vital to operation, long-term reliability, and availability of turbomachinery trains (or strings) which are strategic and expensive components of industrial plants. Sometimes, the entities that ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Multiphase pumps have demonstrated their capability to operate successfully in pumping the product extremes, means 100% liquid up to 100% gas, as well as solids. This duty is difficult for a pump and thus even more difficult ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)This study starts by presenting a typical ethylene plant which will act as the ‘base plant’ for this case study. Then, a ‘low�emission’ ethylene plant is introduced which employs a new cracker technology having ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Laser cladding is gaining acceptance for restoration of turbine and compressor shafts, which has resulted in increased customer demand for laser cladding options. This has increased the number of laser welding suppliers, ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Recent incident reports and studies of pipeline equipment indicate that pump seal performance is likely at the root of a significant increase in releases to the environment. Although these releases are small compared to a ...
