Abstract

Examines factors that increase diethanolamine (DEA) degradation, which reportedly depends on temperature, pressure, gas composition, amine concentration, pH of the amine solution and the presence of metal ions. Plant operators have tried to solve the problem by changing operating conditions and/or installing activated carbon filters. DEA degradation is frequently experienced in gas plants used for removing acidic gases such as carbon dioxide and hydrogen sulfide from light hydrocarbons. Experimental results reveal that degradation is governed by: solubility of CO/sub 2/ in the DEA solution; degree of dissociation of the DEA molecules in solution; interaction of DEA and CO/sub 2/ molecules and/or ionic complexes. Most, or all, these phenomena are affected by temperature, pressure, DEA concentration and pH. A series of tests to determine whether activated carbon is capable of removing impurities from partially degraded DEA solutions showed that this treatment did not remove any major degradation compounds from the solutions.

Pilot plant studies of CO/sub 2/ absorption by DEA at high CO/sub 2/ partial pressures

Conference Ly, Y; Radovich, J - Proc. Gas Cond. Conf.; (United States)

The removal of carbon dioxide from natural gas is a frequently encountered gas conditioning process. Absorption of CO/sub 2/ by an aqueous amine solution is one of the most common methods for CO/sub 2/ removal. In the past total acid gas (CO/sub 2/ + H/sub 2/S) usually accounted for less than 30% of the gas from the producing well. With the use of CO/sub 2/ miscible flooding for enhanced oil recovery and gas from ultra deep wells, the acid gas contant may easily exceed 80%. There is a lack of operating data in the literature for such high CO/sub 2/more »« less
Degradation of aqueous DEA solutions in heat transfer tubes

Conference Meisen, A; Chakma, A

Experiments were performed on the degradation of aqueous diethanolamine (DEA) solutions passing through a coiled heat transfer tube (2.0032 mm ID, 3.175 mm OD, 4.8 m long) immersed in a constant temperature bath. The operating conditions were: DEA flow rate 0.011 to 0.0172 L/s, DEA concentration 20 to 40 wt%, DEA temperature 60 to 200/sup 0/C, CO/sub 2/ partial pressure 1.38 to 4.18 MPa. The degradation rate was found to increase with temperature, DEA concentration and CO/sub 2/ partial pressure; it decreased with solution flow rate. The degradation was accompanied by the formation of a fouling deposit. A simple mathematicalmore »« less
Physical solubility of hydrogen sulfide and carbon dioxide in alkanolamine solutions

Miscellaneous Abu-Arabi, M

The study was undertaken to develop a method that would make direct measurements of acid gases, hydrogen sulfide and carbon dioxide, physical solubilities in aqueous alkanolamine solutions possible. Hydrogen sulfide and carbon dioxide physical solubilities in 20, 35, and 50% by weight diethanolamine aqueous solutions were measured. The solubility measurements were made at acid gas partial pressure up to 1000 psia and temperatures of 80, 150, 240 F. The solubility of nitrous oxide in water and in protonated diethanolamine solution was also determined at 80 F. A method that allows for direct measurements of acid gases physical solubilities has beenmore »« less

Journal Article

A discussion by R.L. Pearce (Dow Chem. Co) at the 57th GPA Annual Conventional (New Orleans 1978) covers hydrogen sulfide removal with methyl diethanolamine (MDEA), including the development, description, and chemistry of the process; the removal efficiency of MDEA; the selectivity of MDEA for hydrogen sulfide removal from gases containing both hydrogen sulfide and carbon dioxide, including a comparison with the selectivities of monoethanolamine (MEA) and diethanolamine (DEA); the MDEA regeneration procedure; the low energy requirement for MDEA gas removal, as compared with other amines; the minor corrosion (about 26 mils/y) experienced at high (approx. 50 wt%) MDEA concentrations; andmore »« less
Mechanism and kinetics of COS-induced diethanolamine degradation

Journal Article Dawodu, O; Meisen, A - Industrial and Engineering Chemistry Research; (United States)

The degradation of aqueous diethanolamine (DEA) solutions by carbonyl sulfide was examined by using a 600-mL well-stirred reactor operating under the following conditions: DEA concentration 20--40 wt %, temperature 120--180 C, COS partial pressure 0.3--1.17 MPa. The reaction products were identified by GC/MS, and reaction mechanisms are developed which conform with experimental observations. The reaction rate constants are determined, and a mathematical model for estimating DEA degradation by COS is presented.
