Kinetics of Co2 with Primary and Secondary Amines in Aqueous Solutions-i. Zwitterion Deprotonation Kinetics for Dea and Dipa in Aqueous Blends of Alkanolamines
The deprotonation kinetics of the DEA--C02 and the DIPA-COZ zwitterions have been studied in aqueous blends of an&es at 298 K. Amine mixtures investigated were: DEA-TEA, DEA-MDEA. DEL-DMMEA, DEA-DEMEA, DIPA-TEA, DIPA-MDEA, DIPA-DMME~ DIPA-DEMEA. FOG each blend the zwitterion deprotonation constant of the additonal base present in solution (i.e. the tertiary amine) was determined. The observed d...
متن کاملبررسی ترمودینامیکی حلالیت گاز سولفید هیدروژن در محلول آبی MDEA،MEA،DIPA و DEA
آزمایش‌های حلالیت، برای گاز سولفید هیدروژن در محلول آبی متیل دی اتانول آمین (MDEA)، دی اتانول آمین (DEA)، مونواتانول آمین (MEA) و دی ایزو پروپانول آمین (DIPA) در دماهای 40، 55 و 70 درجه سانتیگراد و فشارهای جزئی H2S از 20 تا حدود KPa 5000، انجام شد و داده‌های حلالیت برای این آلکانول آمین‌ها به‌دست آمد. این داده‌ها با استفاده از یک اتوکلاو به حجم 250 میلی‌لیتر مجهز به فشارسنج با دقت KPa 7/0 و کنت...
متن کاملThermodynamic Modeling for CO2 Absorption in Aqueous MDEA Solution with Electrolyte NRTL Model
Accurate modeling of thermodynamic properties for CO2 absorption in aqueous alkanolamine solutions is essential for the simulation and design of such CO2 capture processes. In this study, we use the Electrolyte Nonrandom Two-Liquid activity coefficient model to develop a rigorous and thermodynamically consistent representation for the MDEA-H2O-CO2 system. The vapor-liquid equilibrium (VLE), hea...
متن کاملLethal monointoxication by overdosage of MDEA.
A 19-year-old man died after the intake of ten tablets of Ecstasy containing 3,4-methyl-enedioxy-N-ethylamphetamine (MDEA) as the main active ingredient. According to an eyewitness the symptoms of intoxication were strong sweating, sudden aggressiveness followed by hallucinations, subsequent failure of motoric coordination, severe spasms of arms and back, complete depression of the respiratory ...
متن کاملMass Transfer Modeling of CO2 Absorption into Blended MDEA-MEA Solution
In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...
