1. 6. CFD Analysis of Cold Stage Centrifugal Pump for Cooling of Hot IsostaticPress with Validation Case Study

   University essay from KTH/Mekanik

   Author : Shane Hereford; [2017]
   Keywords : CFD; HIP; Quintus Technologies; Centrifugal pump; pump curve;

   Abstract : Hot isostatic pressing (HIPing) has been a growing material treatment process for performance part manufacturingfor over 50 years. This process of using an inert gas at high temperature and pressure to densifymaterials leads to vastly improved material properties by removing pores and other micro- aws. READ MORE

3. 7. De-polymerization and Purification of Kraft Lignin Utilizing the Liquid-Lignin Phase

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Martin Sundin; [2017]
   Keywords : ALPHA; SLRP; Liquid-Lignin; Lignin; Technology and Engineering;

   Abstract : The effects of global warming are apparent and the work towards a sustainable future is underway. In order to reduce the environmental impact caused by the transportation sector, a transition from fossil fuels to those based on renewable resources are important. Using agricultural land to produce raw materials, e.g. READ MORE

4. 8. Maintenance optimisation of centrifugal pumps in a European refinery: : A case study

   University essay from KTH/Industriell produktion

   Author : Andrei Laquet; [2015]
   Keywords : ;

   Abstract : Maintenance has gained credit over the past decades. The oil and gas industry requires efficient maintenance programs due to the hazardousness surrounding the industry. Crude oil margins are also dropping and maintenance yields high controllable costs. Therefore, safety and economy are the driving forces of maintenance optimisation. READ MORE

5. 9. Development of pump geometry for engine cooling system

   University essay from KTH/Kraft- och värmeteknologi

   Author : Joel Björkman; [2015]
   Keywords : pump engine cooling pump curve impeller;

   Abstract : The engine cooling system is an important part of the engine’s performance to achieve optimum temperatures in cylinders and provide cooling to subsystems. With increasing emission demands from legislation, further development of the cooling system is necessary. READ MORE

6. 10. Experimental Transient Behaviour Characterisation of Induction Motor fed by Variable Frequency Drives for Pump Applications

   University essay from KTH/Elektrisk energiomvandling

   Author : Amer Halilovic; [2014]
   Keywords : Variable Frequency Drive; Centrifugal Pump; Induction Motor; Volts-per-Hertz Control; Speed Control; Overdimensioning; Frekvensomriktare; centrifugalpump; asynkronmotor; skalärkontroll; hastighetskontroll; överdimensionering;

   Abstract : The use of variable frequency drives in centrifugal pump applications has raised the question of how to select a drive. Clogging obstacles in waste water applications create unknown transient loads for the pump system. A sudden load increase occurrence can clog the pump if the drive cannot supply enough current to reach the motor’s torque demand. READ MORE
