Waste Heat Doesn't Have to be a Waste of Money- The American & Efird Heat Recovery Project: A First for the Textile Industry
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1991-06)
In 1989 American & Efird, Inc., decided to
upgrade their heat recovery system at its
Dyeing & Finishing Plant in Mt. Holly,
North Carolina. They chose an electric
industrial process heat pump to enhance
heat recovery ...
Repair Severely Damaged Rotors By Submerged Arc Welding.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Severely damaged rotors often can be rebuilt even when damage has occurred to the shaft/rotor forging. Such shop repair returns what would have been a scrapped or degraded rotor to original equipment standards. The repair ...
Efficient Multiphase Pump Station For Onshore Application And Prospects For Offshore Application
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
With oil consumption increasing worldwide, the petroleum industry is being forced to find ever more efficient ways. Not only the exploration of inaccessible and inefficient oil fields, but also the increasing demand for ...
Elimination Of Cavitation-Related Instabilities And Damage In High-Energy Pump Impellers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
The suction-stage impeller of a large crude oil pipeline pump was designed by combining quasi-three dimensional flow analysis with current theories to generate an impeller geometry, which was evaluated in a half-size model ...
Measurement And Prediction Of Full Scale Annular Seal Coefficients
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
The accurate prediction of rotordynamic behavior of centrifugal pumps has increased in importance over the last decade, with a steady increase in speed and power concentration. Designing a pump which has acceptable vibration ...
A User's Engineering Review Of Sealless Pump Design Limitations And Features
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Exxon Chemical like many other petrochemical companies and refineries, is announcing emission plans with a long term goal to achieve continuous emission reduction from the plant sites. Exxon Chemical’s emission plan has ...
Tandem Seals For Near Zero Hydrocarbon Emissions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
More stringent regulatory limits are being placed on gaseous emissions from pumps handling hydrocarbon fluids. For example, new pumps in the Los Angeles Basin are required to have ear zero emissions. The EPA is proposing ...
Changes In Pump Vibration Levels Caused By The Misalignment Of Different Style Couplings
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Unacceptable pump vibrations are sometimes caused by the misalignment of the motor to the pump. Pump vibration increases due to misalignment is dependent on the amount of misalignment and the type of coupling used. The ...
Dual Containment Shells - Added Safety For Magnetically Driven Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Proper function of the shroud is fundamental to the success of the magnetically driven pump. It provides the static seal of the product to the atmosphere without the need for conventional shaft seals. The efficiency and ...
Cooling Towers--Energy Conservation Strategies
(Energy Systems Laboratory, 1991-06)
A cooling water system can be optimized by operating the cooling tower at the highest possible cycles of concentration without risking sealing and fouling of heat exchanger surfaces, tube bundles, refrigeration equipment, ...
