Defining The Proper Operating Time For The Septa Extractor, Abigail Jones
Defining The Proper Operating Time For The Septa Extractor, Abigail Jones
Williams Honors College, Honors Research Projects
Anionic polymerizations are a common type of reaction used to produce synthetic rubber. During these reactions, it is necessary to charge initiators, modifiers, and other substances, through pressurized containers that are sealed with rubber septa. These septa prevent oxygen and moisture from entering the pressurized container, and the reactor, though they need to be cleaned before use to remove other impurities. Currently a glass Soxhlet Extractor is used to remove such impurities, and though effective, it has a limited capacity, so it has to run frequently. This limitation led to the commissioning of the Septa Extractor, which is an automated …
Coolant Capability Study, Christina Grassi
Coolant Capability Study, Christina Grassi
Williams Honors College, Honors Research Projects
The scope of my project is a capability study on different coolants used in manufacturing plants. From this study, the coolant qualities and impact on the manufacturing process will be evaluated in that process and will be documented as a changed standard at the Timken company. Since coolants are sometimes the only fluid on the surface of the parts being manufactured, the rust preventative capabilities will also be studied and evaluated through humidity cabinet testing with and without spiking the coolant with chlorides and sulfates. This project will be carried out on my co-op rotation with the Timken company so …
Comparing Weathering Effects Of Ultraviolet And Xenon Arc Accelerated Aging On Polyvinyl Chloride, Collin Mcinnes
Comparing Weathering Effects Of Ultraviolet And Xenon Arc Accelerated Aging On Polyvinyl Chloride, Collin Mcinnes
Williams Honors College, Honors Research Projects
As the ubiquitousness of polymers increases and begins seeing use in outdoor settings, the need to fully understand how these materials degrade is also necessary. This study aims to compare two known accelerated aging methods, namely an ultraviolet light chamber and a xenon arc light chamber, to understand what differences, if any, manifest in the mechanical, chemical, and cosmetic deterioration of polyvinyl chloride (PVC) after long-term exposure. The study utilizes Fourier-transform infrared spectroscopy, dynamic mechanical analysis, thermogravimetric analysis, and colorimetry analysis to determine the extent of degradation and potential discrepancies between the aging methods.
Cathodic Protection, Michaela Schaber
Cathodic Protection, Michaela Schaber
Williams Honors College, Honors Research Projects
This Honors Research Project explores cathodic protection of reinforcing steel in concrete. It uses NACE SP0408-201 Cathodic Protection of Reinforcing Steel in Buried or Submerged Concrete Structures as the guidelines for experiments and supporting literature. An economic analysis will be included to fulfill Design requirements. Different voltage and other applications will be explored to determine the lowest obtainable cost-efficient corrosion rate. The method of cathodic protection focused on for this project is impressed current cathodic protection.
Amino-Polymer For Co2 Capture By Vacuum Swing Adsorption, Sean Billy
Amino-Polymer For Co2 Capture By Vacuum Swing Adsorption, Sean Billy
Williams Honors College, Honors Research Projects
The applications of sorbent compounds in conjunction with amines and other additives is an innovative method at combating CO2 pollution. An ideal solution would use an amine sorbent to trap the high levels of absorbed CO2 with a low binding energy (less than 45 kJ/mol) and subsequently release them into a stored vessel at ambient temperature with a vacuum swing adsorption system. Attempts at finding a best mixture will be conducted through the usage of a vacuum swing system, utilizing a bed syringe containing the sorbent mix and a vacuum syringe to pull on and subsequently release the CO2 into …
Electrochemical Chloride Removal, Marcus Yudt
Electrochemical Chloride Removal, Marcus Yudt
Williams Honors College, Honors Research Projects
Electrochemical chloride removal (ECR) was tested to see its effectiveness in preventing corrosion on rebar samples within 3.5 wt% sodium chloride concrete. In order to do this, three scenarios were evaluated using electrochemical techniques such as cyclic potentiodynamic polarization and electrochemical impedance spectrsoscopy as well as visual inspections. The three scenarios that were evaluated were one with no chlorides present within the concrete, one that was a worst-case scenario where extreme pitting and corrosion were initiated, and one that had chlorides present and received the ECR treatment. Cyclic polarization curves showed that the ECR and reference without chlorides had similar …
