Overview Of API 682, Second Edition
(Texas A&M University. Turbomachinery Laboratories, 2003)
APIs recent release of Standard 682, Second Edition, represents a major revision to this standard. The latest revision has greatly expanded the scope of the standard by including applications to more pumps, adding new seal ...
Selecting Steam Turbines For Pump Drives
(Texas A&M University. Turbomachinery Laboratories, 2003)
Selecting the right steam turbine for the application can save the purchaser money on initial cost (avoiding oversizing) as well as operating costs (better efficiency). The intent of this paper is to provide steam turbine ...
Understanding The Performance Of A Progressive Cavity Pump With Metallic Stator
(Texas A&M University. Turbomachinery Laboratories, 2003)
Analytical and experimental studies were carried out on a progressive cavity pump (PCP) fitted with a metallic stator with a fixed, positive clearance around the single helical rotor. This eliminates wear and greatly ...
Developments In High Performance Seal Designs For Critical High Pressure Offshore And Pipeline Applications
(Texas A&M University. Turbomachinery Laboratories, 2003)
Ever demanding business and operating conditions have highlighted the need for significant improvements in the reliability of high duty mechanical seals. With platform operators under pressure to minimize deferred oil ...
Design Consideration For A Large Mixer Used In An Agitated Column Application
(Texas A&M University. Turbomachinery Laboratories, 2003)
Industrial agitator or mixer configurations and associated applications present the design engineer with a unique set of challenges. This was especially true when a major chemical company required an agitator for a large ...
Advanced Gas Sealing Systems For Hydrofluoric Acid Alkylation And Other Extremely Hazardous Duties
(Texas A&M University. Turbomachinery Laboratories, 2003)
Seismic Analysis On Modified Service Water Pumps
(Texas A&M University. Turbomachinery Laboratories, 2003)
At one nuclear power plant, the original essential service water pumps were replaced by another set of pumps with higher capacity. The latter were transferred from another “idle” nuclear power plant. Due to some important ...
Reliability Improvement Of End Suction Pump In Severe Service Through Engineered Component Upgrade
(Texas A&M University. Turbomachinery Laboratories, 2003)
An end suction pump for amine service at an Ammonia plant was successfully upgraded by improvement of its components. Two 290 kW (390 HP) pumps, turbine/motor driven, rated for 262 m^3/hr (1,153 gpm) and 271 m (889 ft), ...
Use Of Noncontacting Seals In Volatile Services
(Texas A&M University. Turbomachinery Laboratories, 2003)
Sealing volatile high-pressure fluids has always been a challenge unless the temperature is cold enough to produce a true liquid state around the seal. Even handling true liquids having low boiling points can result in low ...
API 685 Tutorial
(Texas A&M University. Turbomachinery Laboratories, 2003)
For the first time, there is an API standard relating to the use of sealless pump technologies [canned motor pump (CMP) and magnetic drive pump (MDP)]. While sealles technology has been well accepted in chemical process ...
