Application Guidelines For Pumping Liquids That Have A Large Dissolved Gas Content
(Texas A&M University. Turbomachinery Laboratories, 1998)
A case history is presented pertaining to five (four operating and one spare), 150 hp sealless pumps operating in parallel in a closed loop-65° chilled liquid system. The pumping system is designed to use a liquid refrigerant ...
High Temperature Twin Screw Pumps
(Texas A&M University. Turbomachinery Laboratories, 1998)
High temperature applications present many engineering problems. Thermal growth of piping and vessels, coupled with typically lower viscosities at high temperature, has made centerline mounted centrifugal pumps the primary ...
Pump Impeller Lifetime Improvement Through Visual Study Of Leading-Edge Cavitation
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper describes the successful application of cavitation flow visualization to redesign the impeller of an 8.5-MW (11,400 hp) high energy double suction single stage boiler feedpump. Dual purpose of the investigation ...
Methods Of Investigation And Solution Of Stress, Vibration, And Noise Problems In Pumps
(Texas A&M University. Turbomachinery Laboratories, 1998)
This tutorial discusses mechanical problems that occur in pumps and their systems, and how pump users can best detect and solve these problems. The answers to pump operational or reliability problems are often not obvious, ...
Pump Reliability Improvements Through Effective Seals And Coupling Management
(Texas A&M University. Turbomachinery Laboratories, 1998)
Market pressures are demanding cost reductions in the process industries. Most operators are seeking to achieve substantial savings through reductions in the maintenance and “real” operating costs of centrifugal pumps of ...
Reciprocating Pump Dynamic Concepts For Improved Pump Operations
(Texas A&M University. Turbomachinery Laboratories, 1998)
In order to ensure safe, reliable, efficient and cost effective operation of reciprocating pumps, pump dynamics should not be ignored. Pump problems due to dynamics are often difficult to diagnose and solve. Dynamic problems ...
Safety Integrity Levels in Design
(Mary Kay O'Connor Process Safety Center, 1998)
The hazards identified with a new or modified chemical or petroleum refining process can be mitigated in numerous ways. If a system cannot be designed so that it is inherently safe, then other safeguards such as instrumented ...
The API Methodology for risk-biased inspection (RBI) analysis for the petroleum and petrochemical industry.
(Mary Kay O'Connor Process Safety Center, 1998)
Twenty-one petroleum and petrochemical companies are currently sponsoring a project to develop risk- based inspection (RBI) methodology for application in the refining and petrochemical industry. This paper describes that ...
An Application of Risk-based Design Criteria: HF Alkylation Rapid Acid Deinventory System
(Mary Kay O'Connor Process Safety Center, 1998)
A New Training Strategy: Design the Work Enviornent for Continuous Learning
(Mary Kay O'Connor Process Safety Center, 1998)
