Senior Design Reports (CBE)

Hemorrhage due to trauma is the leading cause of preventable death among American soldiers, according the National Institute of Trauma. Uncontrollable bleeding is also seen regularly in civilian incidences of trauma and is a common major surgical complication. The human blood clotting process involves a complex cascade of tightly regulated enzymatic reactions. Two of the most important proteins in this cascade are fibrinogen and thrombin. Thrombin is an enzyme that activates fibrinogen monomers to form a polymeric fibrin network, forming the basis of a blood clot. During trauma, a state of consumptive coagulopathy, the body depletes these two proteins causing ...


Production Of 1,3-Butadiene From Propylene, Amanda Nestlerode, Victor Ngo, Safia Haidermota 2015 University of Pennsylvania

Production Of 1,3-Butadiene From Propylene, Amanda Nestlerode, Victor Ngo, Safia Haidermota

Senior Design Reports (CBE)

Our proposed plant design produces 103 million lb/year of 1,3 butadiene from propylene. Today, there are three chief methods to produce 1,3 butadiene. These include the Houdry process, oxidative dehydrogenation of 2-butenes and steam cracking of saturated hydrocarbons. The latter is the most widely used. The primary motivation behind this project was the production of 1,3 butadiene without the need for olefin cracker C4 crude oil streams. Olefin cracker C4 streams will decrease in availability as the trend towards lighter feedstock increases. Our plant is divided into four sections, namely metathesis, distillation, oxidative dehydrogenation and extractive ...


T-Cell Manufacture For Treatment Of Acute Lymphoblastic Leukemia, Amit Pujari, Chi-Wei Man, Jinsang Park 2015 University of Pennsylvania

T-Cell Manufacture For Treatment Of Acute Lymphoblastic Leukemia, Amit Pujari, Chi-Wei Man, Jinsang Park

Senior Design Reports (CBE)

Adoptive T-cell therapy is a recent medical development that has shown clinical success in treating relapsed acute lymphoblastic leukemia (ALL), a common form of cancer with a poor prognosis. Ironically, the treatment’s greatest advantage is at the same time deterring large pharmaceutical companies from commercializing it. Adoptive T-cell therapy is successful in treating ALL largely because it takes a patient’s own cells and engineers them to fight the cancer. While the autologous nature of the treatment helps to incorporate the engineered T-cells into the patient’s body, it also makes each treatment patient-specific. This does not fit into ...

Fluidized Catalytic Cracking To Convert Biomass To Fuels, Stephen Boust, Mo Green, Serena Machi 2015 University of Pennsylvania

Fluidized Catalytic Cracking To Convert Biomass To Fuels, Stephen Boust, Mo Green, Serena Machi

Senior Design Reports (CBE)

The process of biomass fluidized catalytic cracking (BFCC) has been adapted from the traditional fluidized catalytic cracking of crude oil in petroleum refineries. Instead of a naphtha feedstock, BFCC can accommodate various types of biomass that is cracked into more valuable aromatic and olefinic compounds. This plant inputs forest biomass and will be located in southwestern Louisiana, where wood output exceeds 100 million kg/yr in over ten counties. Biomass, procured in the form of wood chips, must first be dried to a moisture content below 10 wt% and crushed to a particle size of 100-500 micron. The wood sawdust ...


Production Of Btx From Ethane, Arthur Chen, Fiona Crowley, Jonathan Lym, Pablo Sanchez 2015 University of Pennsylvania

Production Of Btx From Ethane, Arthur Chen, Fiona Crowley, Jonathan Lym, Pablo Sanchez

Senior Design Reports (CBE)

This process will produce 0.5 MM tons of benzene, toluene, and xylene (BTX) per year from a feedstock of 0.82 MM tons of fractional-grade ethane. The conversion of ethane to BTX occurs in a steam reformer reactor operating at 1170°F, using a germanium-incorporated H-ZSM-5 zeolite catalyst. After the reaction occurs, the light components are separated from the product stream using a multistage compressor and flash followed by the PRISM separation system. The light hydrocarbons (ethylene, ethane, propylene, and propane) are recycled to the reactor and the hydrogen and methane are burned. The final BTX product is separated ...

Paraxylene From Corn, Antonio Barberio, Alexa Gallegos, Mandi Liu

Senior Design Reports (CBE)

This report details the preliminary design and economic analysis of a paraxylene production plant that uses glucose as the raw material in the form of a hydrolysate obtained from an ethanol plant. The process of taking glucose and converting it to paraxylene happens through three main chemical reactions. The first is the conversion of glucose to hydroxymethylfurfural (HMF), the second is the hydrogenolysis of hydroxymethylfurfural to produce dimethylfuran (DMF) and the last is the reaction of dimethylfuran with ethylene gas to produce paraxyelene. In this report the overall process is broken down in two sections, the first is the production ...


Ngl/Lpg Extraction From Marcellus Shale Gas, Jocelyn Champagne, Freddy Ordonez, Zhiyi Zhang 2015 University of Pennsylvania

Ngl/Lpg Extraction From Marcellus Shale Gas, Jocelyn Champagne, Freddy Ordonez, Zhiyi Zhang

Senior Design Reports (CBE)

This process describes a design in which 6 million metric tons per annum of Marcellus Shale Gas is separated into its components through heat exchangers, pressure drops, and, finally, flowing through distillation columns. The goal was essentially to remove all of the methane gas as the overhead product of the heavy removal column and use the subsequent columns to fraction off heavier hydrocarbons. Heat exchangers could not remove sufficient heat from the feed prior to entering the columns and as a result, the overhead product for the heavy removal column consists of 84% by mole of methane and 15% by ...

A Study On The Micro Electro-Discharge Machining Of Aerospace Materials, Mychal-Drew Moses 2015 Western Kentucky University

A Study On The Micro Electro-Discharge Machining Of Aerospace Materials, Mychal-Drew Moses

Masters Theses & Specialist Projects

Electrical Discharge Machining (EDM) is a non-traditional machining process that uses hundreds of thousands of minute electrical sparks per second to machine any electrically conductive material, no matter the hardness or how delicate it is. EDM allows a much greater range of design possibilities, unconstrained from the traditional machining processes, in which material is removed mechanically by either rotating the cutting tool or the work piece. Shapes that were impossible to machine by any other method, such as deep, precision, square holes and slots with sharp inside corners, are readily produced. It provides accurate geometries in high- aspect ratio holes ...

Nanonickel Catalyst Reinforced With Silicate For Methane Decomposition To Produce Hydrogen And Nanocarbon: Synthesis By Co-Precipitation Cum Modified Stöber Method, Upm Ashik, Wma Wan Daud

upm ashik

Co-precipitation cum modified Stöber method is a continuous process avoiding application of higher temperature treatment before supporting nanometal with SiO2, irrespective of pre-preparation methods. We have conducted the co-precipitation process without undertaking calcination under air in order to avoid even a partial particle agglomeration and hence maintained average particle size [similar]30 nm after enforcing with SiO2. This is the first report adopting such an unceasing preparation for preparing metal/silicate nanostructures. Furthermore, n-Ni/SiO2 nanostructured catalysts were used for thermocatalytic decomposition of methane to produce hydrogen and carbon nanotubes. The catalyst was found to be very stable and the ...

Thermal Invisibility Based On Scattering Cancellation And Mantle Cloaking, M Farhat, P.-Y. Chen, H Bagci, C. Amra, S Guenneau, A Alù

Electrical and Computer Engineering Faculty Research Publications

We theoretically and numerically analyze thermal invisibility based on the concept of scattering cancellation and mantle cloaking. We show that a small object can be made completely invisible to heat diffusion waves, by tailoring the heat conductivity of the spherical shell enclosing the object. This means that the thermal scattering from the object is suppressed, and the heat flow outside the object and the cloak made of these spherical shells behaves as if the object is not present. Thermal invisibility may open new vistas in hiding hot spots in infrared thermography, military furtivity, and electronics heating reduction.
