Study of Various Aqueous and Non-Aqueous Amine Blends for Hydrogen Sulfide Removal from Natural Gas
processes Article Study of Various Aqueous and Non-Aqueous Amine Blends for Hydrogen Sulfide Removal from Natural Gas Usman Shoukat , Diego D. D. Pinto and Hanna K. Knuutila * Department of Chemical Engineering, Norwegian University of Science and Technology (NTNU), 7491 Trondheim, Norway; [email protected] (U.S.); [email protected] (D.D.D.P.) * Correspondence: [email protected] Received: 8 February 2019; Accepted: 8 March 2019; Published: 15 March 2019 Abstract: Various novel amine solutions both in aqueous and non-aqueous [monoethylene glycol (MEG)/triethylene glycol(TEG)] forms have been studied for hydrogen sulfide (H2S) absorption. The study was conducted in a custom build experimental setup at temperatures relevant to subsea operation conditions and atmospheric pressure. Liquid phase absorbed H2S, and amine concentrations were measured analytically to calculate H2S loading (mole of H2S/mole of amine). Maximum achieved H2S loadings as the function of pKa, gas partial pressure, temperature and amine concentration are presented. Effects of solvent type on absorbed H2S have also been discussed. Several new solvents showed higher H2S loading as compared to aqueous N-Methyldiethanolamine (MDEA) solution which is the current industrial benchmark compound for selective H2S removal in natural gas sweetening process. Keywords: H2S absorption; amine solutions; glycols; desulfurization; aqueous and non-aqueous solutions 1. Introduction Natural gas is considered one of the cleanest forms of fossil fuel. Its usage in industrial processes and human activities is increasing worldwide, providing 23.4% of total world energy requirement in 2017 [1]. Natural gas is half of the price of crude oil and produces 29% less carbon dioxide than oil per unit of energy output [2]. -

Degradation of Amine-Based Solvents in CO2 Capture Process by Chemical Absorption
CORE Metadata, citation and similar papers at core.ac.uk Provided by Heriot Watt Pure Degradation of amine-based solvents in CO2 capture process by chemical absorption F. Vega1, 2, A. Sanna2, B. Navarrete1, M.M. Maroto-Valer2, V. Cortés1 1Chemical and Environmental Engineering Department, School of Engineering, University of Seville, C/ Camino de los Descubrimientos s/n 41092 Sevilla, Spain, Phone: 954481397, [email protected] 2Centre for Innovation in Carbon Capture and Storage (CICCS), School of Engineering and Physical Sciences, Heriot-Watt University, EH14 4AS, Edinburgh, UK ABSTRACT Carbon dioxide capture and storage (CCS) technologies have been proposed as promising alternative to reduce CO2 emissions from fossil-fuel power plants with post- combustion capture. Absorption by aqueous amine-solutions is considered the most mature and industrially developed technology for post-combustion capture. One of the most significant issues hindering a large deployment of this technology is potential amine degradation. Amines degrade in presence of O2, CO2, NOx, SO2 and heat resulting in solvent loss, equipment corrosion and generation of volatile degradation compounds. Two types of degradation have been identified in the literature, namely oxidative and thermal degradation. A review of the amine-based solvents, its main degradation products, the apparatus and analytical methods most widely used, as well as the mechanism proposed and kinetic studies are presented and discussed here. Moreover, amines emissions from CO2 capture units can react in the atmosphere via photo-oxidation and also via NOX reactions to give nitrosamines and nitramines, which are potentially harmful to the human health and the environment. A discussion of the recent works on atmospheric degradation of amine solvents is also included in this review. -

Final Amended Report on the Safety Assessment of Ethanolamine And
Final Amended Report On the Safety Assessment of Ethanolamine and Ethanolamine Salts as Used in Cosmetics March 27, 2012 The 2012 Cosmetic Ingredient Review Expert Panel members are: Chairman, Wilma F. Bergfeld, M.D., F.A.C.P.; Donald V. Belsito, M.D.; Ronald A. Hill, Ph.D.; Curtis D. Klaassen, Ph.D.; Daniel Liebler, Ph.D.; James G. Marks, Jr., M.D., Ronald C. Shank, Ph.D.; Thomas J. Slaga, Ph.D.; and Paul W. Snyder, D.V.M., Ph.D. The CIR Director is F. Alan Andersen, Ph.D. This report was prepared by Monice M. Fiume, Senior Scientific Analyst/Writer, and Bart Heldreth, Ph.D., Chemist, CIR. Cosmetic Ingredient Review 1101 17th Street, NW, Suite 412 ♢ Washington, DC 20036-4702 ♢ ph 202.331.0651 ♢ fax 202.331.0088 ♢ [email protected] ABSTRACT: The CIR Expert Panel assessed the safety of ethanolamine and 12 salts of ethanolamine as used in cosmetics, finding that these ingredients are safe in the present practices of use and concentrations (rinse-off products only) when formulated to be non-irritating. These ingredients should not be used in cosmetic products in which N- nitroso compounds may be formed. Ethanolamine functions as a pH adjuster. The majority of the salts are reported to function as surfactants; the others are reported to function as pH adjusters, hair fixatives, or preservatives. The Panel reviewed available animal and clinical data, as well as information from previous relevant CIR reports. Since data were not available for each individual ingredient, and since the salts dissociate freely in water, the Panel extrapolated from those previous reports to support safety. -

Box 13501 Research Triangle Park, North Carolina 27709 November 2002 Toxicological Summary for Dimethylethanolamine and Selected Salts and Esters 11/2002 Executive Summary Nomination Dimethylethanolamine (DMAE) was nominated by the NIEHS for toxicological characterization, including metabolism, reproductive and developmental toxicity, subchronic toxicity, carcinogenicity and mechanistic studies. The nomination is based on the potential for widespread human exposure to DMAE through its use in industrial and consumer products and an inadequate toxicological database. Studies to address potential hazards of consumer (e.g. dietary supplement) exposures, including use by pregnant women and children, and the potential for reproductive effects and carcinogenic effects are limited.
