This book was released on 2018-05-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.
Download or read book Propylene Glycol Production from Glycerol Cost Analysis Propylene Glycol E12A written by Intratec and published by Intratec. This book was released on 2019-09-17 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Propylene Glycol production from glycerol using a vapor-phase process. The process examined is similar to Davy Technologies process. In this process, technical grade glycerol (99.5 wt% glycerol content) is used as feedstock and ethylene glycol is generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Glycerin, Davy Process Technology, DPT, Propane-1,2-diol, Hydrogenolysis, Cargill, Ashland

Download or read book Equilibrium Limitations and Selectivity on Conversion of Glycerol to Propylene Glycol written by Lizanette Rivera-Ramos and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogenolysis of glycerol to propylene glycol was performed at lower temperatures and pressures using concentrated glycerol. Reactions were carried out at 180, 200, 220, and 240°C and at a system pressure of 1, 2, and 4 bars in the presence of a copper-chromite catalyst. The effect of temperature, pressure, residence time, water content, and H2: Glycerol mole ratios were evaluated. All results indicate that lower temperatures and higher pressures promote the selectivity on conversion of glycerol to propylene glycol. The amount of byproducts decreased with decreasing the residence time. Product quality correlates with lower water content. Catalyst productivity increased with decreasing H2: Glycerol mole ratio. An optimal H2: Glycerol mole ratio is near 15:1. Lower temperatures (220°C) are the preferred operated conditions to increase the catalyst productivity. The results are also fully consistent with a two-step reaction in which the second step of conversion of acetol to propylene glycol is equilibrium limited.

This book was released on 2016-05-01 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Propylene Glycol production from glycerol using a liquid-phase process. The process examined is similar to Suppes process. In this process, technical grade glycerol (99.5 wt% glycerol content) is used as feedstock and ethylene glycol is generated as by-product. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) Keywords: Glycerin, Senergy Chemical, Propane-1,2-diol, Hydrogenolysis
