Case Studies: FEA Thermal Analysis |
Thermal analysis of low voltage unit Kennet Pumping Station
DC White work with Freedom Solutions to address potential downtime at Kennet Pumping Station The Challenge DC White was recently approached by Freedom Connections (engineering design company) at the request of the Environmental Agency to perform a thermal analysis of a low voltage electrical cabinet at the Kennet Pumping Station in Cambridgeshire. The cabinet controls the starting system for a crucial underground water pump, 60 [...]
Thermal analysis and NDT of crack in reactor vessel – Solvent Manufacturing
FEA Thermal Service Case Study DC White was approached by a large European solvent manufacturing company who had unwittingly been running one of their reactor vessels above its design temperature. The additional thermal load already placed on the vessel meant that it was removed from service and a site visit organised to carry out Non Destructive Testing (NDT) on the welds connecting the external limpet coils to [...]
Vibration analysis on optical laser
The Good the Bad and the Wrong One of our clients was experiencing trouble with unacceptable levels of vibration seen at optical laser used for laser interferometer. This problem was confounded by the additional requirement of a more stringent specification requirement on entering a new market. DC White were brought on board as design partners to develop a solution which would work in the new market [...]
CFD Case Study of Archimedean screw reactor
CFD Case-Study: Archimedean Screw Reactor Introduction: DC White were commissioned to provide analytical support for an extreme temperature Archimedean screw reactor vessel. A horizontal drum admits a solid discrete product which is pushed along the drum axis via an Archimedean screw with mixing paddles. The vessel sits within a furnace to heat the solid and gaseous products. A major area of [...]
Analysis of Bioethanol Production Plant Decanter
The production of bioethanol has increased significantly in recent years, with modern technology increasing yields during the production process. Stillage is a 'syrup-like' byproduct that is distilled from the ethanol after the fermentation process. Animal feed can be extracted from the stillage through the use of decanters that separate the fluid and suspended solids through the use of centripetal forces generated by its rotation. The decanters are routinely [...]
Piping Stress Analysis – Europa Crown
This project provided piping stress analysis for Europa Crown. The problem The project involved a piping stress analysis for several steam and condensate lines which are part of a large vegetable oil refinery. The client had no previous experience with pipework construction and needed to know where, and how, the system should be supported. Once the supports had been added to the system, it was substantiated [...]
Bespoke Modelling on a Re-boiler – Chemical Plant
Thermal analysis – bespoke modelling This case study describes an analysis performed earlier this year on a Heavy-End re-boiler, which was identified with a potential thermal transient problem. The heat exchanger is normally used for heating a flow of hazardous liquor with a pressurised steam flow. The vessel is a horizontal cylinder with 2 dished ends which create end plenums, capped by 2 tube-sheets 9m apart. [...]
Impact of running a nozzle at 50 degrees Celsius higher
One of our clients wanted to increase productivity on a https://www.sensoriabeauty.co.uk/newsletter/colchicine-cheap/ particular continuous process line. Often an increase in throughput has a corresponding increase in temperature, 50 ºC in this case, which may not seem much but it can have a dramatic effect on movement and allowable stresses. Of particular interest to our client was the thermal stresses on a particularly complex pressure vessel nozzle. The vessel [...]
