This work presents an optimized design of a methyl diethanolamine CO 2 capture unit for clean hydrogen production via steam methane reforming natural gas, where is captured from the pressurized water-gas shifted syngas. We propose modified version standard MDEA-based process flowsheet, and we optimize operating conditions by solving multi-objective optimization problem to minimize energy consum...

In the treatment of many fuel gases such as biogas, natural gas, syngas, and so on, tertiary alkanolamines play an important role in selective removal H2S with respect to CO2. The selectivity might be required for various reasons: more stringent specifications, optimize performance Claus unit, lower cost CO2 capture, on. H2S/CO2 is mainly kinetic and, a lesser extent, thermodynamic. A novel exp...

In order to increase the rate of gas absorption, chemical reaction in the liquid phase is considered. The purpose of this paper was to simulate gas absorption process by a liquid film over a spherical packing incorporating eddy viscosity and diffusivity. Second order chemical reaction for two different cases (fast and slow) were considered. The system partial differential equations obtained...
