Optimization Of Styrene From Ethylbenzene Case Study, Jabria Daria Thompson

Honors Theses

The following pages detail the optimization process of styrene from ethylbenzene in the Styrene Production Plant, Unit 500. There were two parts of the assignment, each with slightly different end goals. The goal of the first part of the assignment, was to create a process that would effectively and efficiently increase the negative Net Present Value (NPV) of the production plant. Procedures taken in this process included developing a working kinetic process simulation model and optimizing this model through unit operations and heat integration, as well as developing an accurate economic model that will be used to evaluate the proposed …

The Design And Economic Optimization Of A Warehouse Refrigeration System, Hannah Talbot

Honors Theses

The purpose of this project was to design a cool warehouse refrigeration system for Acme Frozen Foods, Inc located in Newark, New Jersey. The refrigeration system was used to cool eighteen 300,000 ft³ refrigerated units (200 ft x 100 ft x 15 ft), each requiring 200 cooling tons of refrigeration at a level of 0 F. The scope of this project included determining the appropriate refrigeration cycle, selecting the most desirable refrigerant, and temperature ranges to optimize the performance of the system. This project also considered the economic cost of the power needed to run the refrigerated units and …

Thermal And Thermophysical Properties Of Anionic Amines And Their Aqueous Solutions For Co2 Capture In Confined Environments, Randi Swanson

Honors Theses

Air revitalization for the International Space Station (ISS) has been identified by NASA as a mission critical need which requires improvement. The current method uses13X zeolite, a solid adsorbent, to adsorb carbon dioxide. While this is effective, the zeolite adsorbent produces dust that is unwelcome on the space station. Furthermore, the adsorbentis too sensitive to humidity in moderate temperature gas streams [1]. Aqueous solutions of ionic amines show promise as a safe and efficient solution, as they do not volatilize and are not water sensitive [2]. Specifically, anionic amines have the most potential because of the amine functional group’s ability …

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 …

Distillation Optimization In The Pharmaceutical Industry, Clayton Carter

Honors Theses

Distillations are commonly used throughout industry to perform separations by phase change. producing a liquid phase and vapor distillate. However. the process of distilling can be slow and energy intensive, providing a limitation in the production process. Possible improvements to current distillation systems were considered on the basis of thermal efficiency, material throughput (cycle time), and material tolerance. Consideration was given to ensure maintenance is straightforward and relatively quick, as fouling, contamination and tank utilization were concerns. Economic viability of the improvements was completed to determine the project benefit. The optimized design offers increased efficiency for production lines.
