Nuclear Energy As A Reliable And Safe Source Of Power Generation, Sarup Dhungana

Honors Theses

There is a high demand of energy for generating civil applicable power in the world and in the USA, correspondingly. The world has been consuming various sources to extract the power to meet its demands. Most of the power sources include renewable and non-renewable sources like fossil fuels, natural gas, coal, water, solar, wind, and nuclear power. Although most of these sources have many advantages in terms of their capacity and cost of production, nuclear power can be categorized as the emerging driving force in the United States and in the world for power generation, because of its reliability and …

Design And Analysis Of A Process To Convert Methanol Into Dimethyl Ether, Elisa M. White

Honors Theses

A recent economic downturn led to the loss of a contract for a company that sells methanol. The company has two options to recover some of the profit lost from the contract termination. One option is to sell the excess methanol at the spot market price, and the second option is to implement a process to convert the excess methanol into dimethyl ether. This project investigated the implementation of a process to convert the methanol from the lost contract into dimethyl ether. The process was simulated in AVEVA Process Simulation to estimate the size of equipment needed. A toller provided …

Aveva Competition 2021: Dimethyl Ether Production Process, Nicholas Gaouette

Honors Theses

The following study was conducted to assess the economic and process feasibility of a dimethyl ether (DME) production process. A portion of the methanol produced by an existing facility would be used to produce DME through a dehydration reaction. DME production is being considered as a means to compensate for lost methanol revenue, as methanol prices have recently decreased and an excess supply is present on the open market.

The first milestone in the study was the construction of a working process model within AVEVA Process Simulation. This steady-state process model would provide information essential to further design and optimization …

Ethylbenzene Production Case Study And Optimization, Brandon Borek

Honors Theses

The objective of this project was to investigate the process of producing ethylbenzene from the liquid-phase reaction of ethylene and benzene and perform parametric and topological optimizations to increase the net present value of the production facility. To do so, the base case conditions of the process were modeled and quantified economically followed by an investigation into the existing process to determine conditions that could be altered to improve the economic viability of the project. After optimizing the parametric conditions and topology of the process, the net present value of the project was increased by 305 million dollars to 191 …

Design, Analysis, And Optimization Of A Process To Produce Dimethyl Ether From Methanol, Thomas Mathwig

Honors Theses

The company that the engineering team works for is facing a contract loss with one of its customers of methanol. To avoid economic losses, a process has been proposed for converting the unused methanol to dimethyl ether (DME) through a dehydration reaction. After a preliminary simulation of the base case and optimization of the distillation column, an Equivalent Annual Operating Cost (EAOC) of $140,000 was calculated for the column. The EAOC was the sum of the annualized capital investment and the annual operating cost. Determining the process to be worth pursuing, a Toller was brought in to provide rental equipment …

Comparative Analysis Of Simulation Models Of The Production Of Ethylbenzene, Osariemen Imafidon

Honors Theses

Process Engineering is all about making sure a raw material can become the desired product with as little variation as possible, while achieving the customer's specifications. Many equipment used for chemical processes cannot be physically inspected during operation at steady state, hence, the need for simulation software. The objective of this study was to compare the results of three different simulation packages to evaluate their efficacy within process design.

This study focused on the economic analysis of the production of Ethylbenzene using various models. The base case variables were inputted into each model to simulate the calculations for a fully …

Ultrasound-Assisted Post-Pyrolysis Magnetization Of Microporous Biochar For Effective Removal Of Heavy Metals, Ronish Shrestha

Honors Theses

Low cost and efficient adsorption of heavy metals from wastewater and thorough removal of adsorbent after water treatment have become the two essential needs for the commercial use of any adsorbent. Biochar (BC), the solid byproduct of pyrolysis with microporous carbonaceous structure, has been increasingly recognized as an efficient adsorbent for a vast number of pollutants. Magnetization, though eases the separation and reuse of BC, significantly reduces its adsorption capacity to a comparatively much higher extent. In this study, a hybrid post-pyrolysis magnetization was developed which sustained and even significantly increased the adsorption capacity of biochar. The process included i) …

How Moisture Content Levels And Packing Density In Soil Affect Crude Oil Spreads, Shaylin N. Williams

Venture: The University of Mississippi Undergraduate Research Journal

Crude oil spills are one of the most destructive disasters that can occur, and they are extremely difficult to recover from. Many studies focus on what can be done to clean these crude oil spills, but more research should be focused on means of prevention. Currently, very little is known about how the moisture content levels and the packing efficiency of soil can affect an oil spill. These two factors alone can offer a variety of information to environmental agencies, manufacturers, and refineries. Through utilization of a chemical engineering lab, a recording mechanism, and ImagePro software, data was collected and …
