Chemical Engineering Projects
Chemical engineering is the branch of engineering that deals with the application of physical science (e.g., chemistry and physics), and life sciences (e.g., biology, microbiology and biochemistry) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms. This section is dedicated to chemical engineering projects, project sample, design project, chemical engg project ideas, final year projects in chemical engineering for students, project topics, project list, chemical engineering project titles.
Mining waste and wetlands
This thesis gives a structural description of wetlands and some processes that are vital for the treatment of metal-polluted waters in wetlands. A number of factors affecting the productivity and useful lifetimes of treatment wetlands are also described. The sources of acid mine drainage (AMD) and ways to minimize production of AMD such as soil [...]
On The Fluid Dynamics of Virtual Impaction and The Design of a Slit Aerosol Sampler
It has been long established that Reynolds number effects can lead to flow instabilities and/or transition from laminar to turbulent flow regimes. The nature of free shear jets is well understood and heavily covered in the fluid mechanics literature. On the other hand, the study of confined nozzles presents some challenges and is still a [...]
Development of a method for pre-damping in laboratory offset printing units
At the Iggesund mill there are several methods and equipments in laboratory scale that simulate the offset printing process in order to evaluate mottle tendency or ink tack for instance. However, it is not possible to study the effect of pre-damping prior to printing on these properties, which mostly is the case in industrial printing. [...]
Micelles of Polybutadiene-b-Poly(Ethylene Oxide) in a Binary Solvent System
We studied the assembly behavior of a polybutadiene-b-poly(ethylene oxide) diblock copolymer in methanol, cyclohexane, and the corresponding partially miscible binary solvent system. Dynamic light scattering indicates that the copolymer forms coexisting spherical and cylindrical micelles in both of the pure solvents. In the binary solvent system… Contents Chapter 1: Introduction Chapter 2: Theory 2.1 Micelle [...]
Synthesis and Characterization of Diblock Copolymer Templated Iron Oxide Nanoparticles
Templating ordered assemblies of magnetic oxide nanoparticles within self-assembled diblock copolymers of varying morphologies is an important problem with a wide applicability such as in electromagnetics, optical devices, metal catalysts, medicine and biology. In this thesis, the effects of different polymer structures on particle ordering and resultant magnetic properties have been investigated using various microstructure [...]
Thermoreversible Transitions Between Self-Assembled Nanostructures in Aqueous Solution
We study an unusual transition between two different types of self-assembled structures in aqueous solutions. Mixtures of a cationic surfactant, CTAB and the organic compound, 5-methyl salicylic acid (5mS) spontaneously self-assemble into unilamellar vesicles at room temperature… Contents Chapter 1. Introduction and Overview 1.1. Problem Statement and Proposed Approach 1.2. Significance of this Work 1.3. [...]
Aerosol Impactor – Aerosol Sampling
The collection and characterization of chemical and biological aerosols is vital to several aspects of particle research for example toxicological studies, pollutant sampling, and biohazard analysis. This study presents the simulation of a low cutpoint, high volume aerosol sampling gadget referred to as virtual impactor
Coil-to-Helix Transition of Poly(ethylene oxide) in Solution
Poly(ethylene oxide) (PEO) is a simple polymer with repeating units [- C - C - O -] soluble in organic and aqueous solvents. The carbon atoms are hydrophobic; the oxygen atoms are hydrophilic and participate in hydrogen bonding… Contents Chapter 1: Introduction Chapter 2: Prior Work Aqueous Solutions of Poly(ethylene oxide) Theory Experiment and Simulation [...]
Relaxation and Stiffening Dynamics of a Single Semiflexible Polymer Chain
Both synthetic and biological polymers are a challenge to study because of the many features and functional roles they carry. A good understanding of the macromolecule’s dynamical properties is essential for biological processes such as the cytoskeleton … Contents 1 Polymer Physics 1.1 Introduction 1.2 Overview of Chapters 2 Numerical Method 2.1 Introduction 2.2 Model [...]
