Abstract:

The formation of subcritical methanol clusters in the vapor phase is known to complicate the analysis of nucleation measurements. Here, we investigate how this process affects the onset of binary nucleation as dilute water–methanol mixtures in nitrogen carrier gas expand in a supersonic nozzle. These are the first reported data for water–methanol nucleation in an expansion device. We start by extending an older monomer–dimer–tetramer equilibrium model to include larger clusters, relying on Helmholtz free energy differences derived from Monte Carlo simulations. The model is validated against th

Abstract:

The work presented in this thesis addresses the issue of hydration of a simple amphiphile-like molecule; methanol. High-resolution Raman spectroscopy is used to study methanol-water mixtures over the whole concentration range. A highly non-linear dependence of the carbon-oxygen and carbon-hydrogen stretching frequencies with composition is observed. The data suggest the first global picture of the progressive hydration of methanol: water first breaks up the molecular chains which exist in pure methanol, and then completely hydrates the hydroxyl groups before solvating in hydrophobic methyl gro

Adsorption of ethylene glycol is favourable to all of these surfaces with Al2O3 (0001) and PdO (101) showing the most favourable adsorption at -168 kJ mol-1 and -135 kJ mol-1 respectively. The MgO surfaces showed adsorption energies between -80 kJ mol-1 and -100 kJ mol-1, and the gold nanoparticles showed lower adsorption energies at approximately -35 kJ mol-1. Barriers to O-H

PEMWEs have several advantages in comparison with the alkaline electrolysis such as ecological cleanness, low power consumption, small mass, and high purity of the evolved gases.

It begins with an overview of the most important types of nanostructured surfaces, their preparation and characterization. It then considers the fundamentals of reaction processes, focusing on the kinetics and dynamics of adsorption and desorption. It also describes the experimental techniques used in the context of reaction studies under ultrahigh-vacuum conditions. Finally, it presents some experimental results of model reactions,

This work presents a robust flowsheet design for the recovery and purification of waste solvent streams containing ethyl acetate (EtAc), methanol (MeOH), and water. Separation of this mixture is challenging due to the presence of two azeotropes: a homogeneous EtAc-MeOH azeotrope and a heterogeneous EtAc-water azeotrope. These azeotropes create a distillation boundary that divides the ternary composition space into two distinct regions, making separation via conventional distillation difficult. Additionally, the wide variability in waste solvent compositions requires a versatile design, as flow

Potentiodynamic polarization curves on SS316 were performed in methanol-water-1M LiCl at different methanol concentrations ranging from (0 - 99 wt%).

In natural gas production and processing applications, methanol is commonly injected into natural gas streams containing water to prevent the formation of hydrates in gas lines and subsequent equipment damage. However, gas chromatographs (GCs) at field sites are typically not equipped to identify or measure methanol, and unless excess methanol is expected to carry over into a gas stream, samples sent to a laboratory are not likely to be analyzed for methanol. As a result, the potential exists for errors in gas property determination, particularly in heating value and sound speed. A previous PR

This report provides a review of the state-of-the-art knowledge on glycol-water mixtures carried over to dry gas transmission pipelines, i.e., physical properties, the causes of entry, and the corrosiveness. Findings obtained from literature include: Glycol-water mixtures can be potentially accumulated in dry gas transmission pipelines. Operation conditions of the dehydration unit should be optimized to control the amount and corrosiveness of glycol-water being carried over into transmission lines. The glycol-water hold-up in dry gas transmission pipelines contain high glycol content, i.e., gr

Abstract:

Research has assessed the accuracy of two commercially-available hydrocarbon dew point (HCDP) analyzers, an Ametek� Model 241 CE II and a Michell Condumax II. During a previous phase of this project, both automated analyzers, along with a Bureau of Mines chilled mirror device serving as a reference, were tested on gravimetrically-prepared gas blends chosen to simulate a transmission-quality gas and a production gas. The measurement repeatability of both units was found to be better than the manual chilled mirror. Trends in the analyzer and manual chilled mirror measurements suggested that diff
