Robust optimization of a post-combustion CO2 capture absorber column under process uncertainty

Control of a post-combustion CO2 capture plant during process start-up and load variations

Dynamic and flexible operation of a carbon capture plant is important as thermal power plants must be operated very flexibly to accommodate large shares of intermittent energy sources such as wind and solar energy. To facilitate such operation, dynamic models for simulation, optimization and control system design are crucial. In this paper, we present a dynamic mathematical model for the absorp...

Biomass Waste Carbon Materials as adsorbents for CO2 Capture under Post-Combustion Conditions

A series of porous carbon materials obtained from biomass waste have been synthesized, with different morphologies and structural properties, and evaluated as potential adsorbents for CO2 capture in post-combustion conditions. These carbon materials present CO2 adsorption capacities, at 25°C and 101.3 kPa, comparable to those obtained by other complex carbon or inorganic materials. Furthermore,...

Robust optimization under multiband uncertainty

We provide an overview of the main results that we obtained studying uncertain mixed integer linear programs when the uncertainty is represented through the new multiband model [4]. Such model extends and refines the classical one proposed by Bertsimas and Sim [2] and is particularly suitable in the common case of arbitrary non-symmetric distributions of the uncertainty. Our investigations were...

Water Vapor Adsorption on Biomass Based Carbons under Post-Combustion CO2 Capture Conditions: Effect of Post-Treatment

Wet impregnation of a commercial low cost silica using DETA for a fast post-combustion CO2 capture process

This work presents an economic and simple method to manufacture low cost, but effective adsorbents for CO2 capture through impregnating DETA to a low cost, porous silica gel. The results have demonstrated that the low cost silica gel impregnated by low molecular-weight amine is stable and work very well at a temperature up to 130 C. The developed adsorbent has a fast adsorption kinetics and can...
