Cavitation And Recirculation Troubleshooting Methodology
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
High reliability and large rangeability are required of pumps in existing and new plants which must be capable of reliable on-off cycling operations and especially low load duties. The reliability and rangeability target ...
Controlling Emissions To Atmosphere Through The Use Of A Dry-Sliding Secondary Containment Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Increasing concern over the emission of hazardous compounds to the atmosphere has led to stricter regulations regarding the acceptable amount of leakage from pumps. This is forcing the users and manufacturers of pumps and ...
Cooling Towers Make Money
(Energy Systems Laboratory (http://esl.tamu.edu), 1995-04)
Question:-Why is the low bidder system a sacred cow? If contractors understand, by specifications, that the second low bidder will be awarded the contract all bidders will do their best to provide 100% performing equipment. ...
Canned Motor And Magnetically Coupled Pumps - Applications, Operations, And Maintenance In A Chemical Plant
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The environmental requirements that drive chemical producers to move more and more to the use of the “sealless” pump are described. The development of the sealless pumps in the European industrial community and their ...

Design And Testing Of A Zero-Net Radial Taper, Radially Compliant Face Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Conventional seal designs, the net radial taper changes with operating conditions so that contact is not always maintained across their entire width and leakage can occur. The “zero-net” face seal combines two ideas to ...
Brayton Cycle Heat Pump for VOC Control
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
The first full size continuous operation Brayton Cycle Heat Pump (1)(2)(3) application for VOC recovery occurred in 1988. The mixed solvent recovery system was designed and supplied by NUCON for the 3M facility in Weatherford, ...
Examples of Process Modifications that Reduce Waste
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
The ideal approach to reducing or eliminating waste products is to avoid making them in the first place. This article will examine numerous process modifications that have accomplished that goal. We'll look at changes to ...
Variables Influencing HRSG Designs
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
Heat Recovery Steam Generators (HRSG's) are widely used in chemical plants, refineries, incineration and cogeneration systems and in general for recovering energy from waste gas streams. In applications such as hydrogen ...
Enhanced Mechanical Seal Performance Through Proper Selection And Application Of Enlarged-Bore Seal Chambers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Recent studies of enlarged-bore seal chambers document the influence of chamber design on seal performance. The studies utilize laser Doppler velocimetry (LDV), high speed videography, and computational fluid dynamics (CFD) ...
