CO2 Corrosion on Natural Gas Compressors: Criteria and Guidelines
(Texas A&M University. Turbomachinery Laboratories, 2013)
Liquid water and CO2 can easily lead to carbon steel corrosion, especially at high pressures. Corrosion can happen either during normal running or during pressurized standstill conditions. The present paper describes three ...
Case Studies in Using Whole Building Interval Data to Determine Annualized Electrical Savings
(Energy Systems Laboratory (http://esl.tamu.edu), 2009-11)
Whole building interval analysis to determine savings from energy reduction measures is addressed in several guidelines. The whole building method has typically focused on measured savings where baseline regression models ...
Electric Driven Centrifugal Compressor - Super Synchronous Vibrations of the High Speed Shaft Line: Observations, Assessment and Resolution
(Texas A&M University. Turbomachinery Laboratories, 2013)
An unacceptable vibratory behavior was encountered in 2012 during the full load string test of an electric driven centrifugal compressor. The vibrations were observed on the high speed part of the shaft line and both ...
Investigation Results for Surge Phenomena of Centrifugal Compressor Related with Piping Arrangements and Test Conditions
(Texas A&M University. Turbomachinery Laboratories, 2013)
The shop performance test of a hydrogen recycle gas compressor for refinery plant was conducted with the suction pressure of 50barA based on ASME PTC-10 Type-2 test. During testing, a surge phenomenon was observed at a ...
A Probabilistic Approach for Compressor Sizing and Plant Design
(Texas A&M University. Turbomachinery Laboratories, 2013)
Equipment sizing decisions in the Oil and Gas Industry often have to be made based on incomplete data. Often, the exact process conditions are based on numerous assumptions about well performance, market conditions, ...
Comparison Of Different Variable Speed Compression Train Configurations With Respect To Rotordynamic Stability And Torsional Integrity
(Texas A&M University. Turbomachinery Laboratories, 2012)
Wherever a variable speed gas compression train is needed for Oil & Gas upstream applications as well as for gas storage applications the primary decision has to be made between a gas turbine driver and an electric motor ...
The Impact of Residential Air Conditioner Charging and Sizing on Peak Electrical Demand
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
Electric utilities have had a number of air conditioner rebate
and maintenance programs for many years. The purpose of
these programs was to improve the efficiency of the stock of
air conditioning equipment and provide ...
Improving Reliability On A Centrifugal Compressor Experiencing Frequent Bearing Failures
(Texas A&M University. Turbomachinery Laboratories, 2012)
A 1957 vintage multi-stage centrifugal compressor, critical in a refrigeration process, had a history of poor reliability and LP stage bearing failures. Around 1995 the HP casing had been replaced and upgraded. In early ...
A Comparative Heat Transfer Examination of Structural Insulated Panels (SIPs) With and Without Phase Change Materials (PCMs) Using a Dynamic Wall Simulator
(Energy Systems Laboratory (http://esl.tamu.edu), 2008-12)
The main focus of this paper was to present data to advance the design of a previously developed thermally-enhanced structural insulated panel (SIP) that had been outfitted with phase change materials (PCMs) (Medina et ...
Reducing Life Cycle Cost By Energy Saving in Pump Systems
(Energy Systems Laboratory (http://esl.tamu.edu), 1999-05)
Pumps consume about 15% of all electricity generated world wide. In the USA alone this accounts for over 130TWh per annum. A saving of only 1% would amount to $80 million in electricity cost. The importance of energy saving, ...
