“…Indeed, the higher CO 2 content in coal-fired flue gases means that the separation is easier to achieve. These reported economic assessments 49,50 provide comparison points for our work. We have observed significant variation between these reported estimates and our work (3 to 10 times).…”

“…In Scenario 2 and Scenario 3, the auxiliary phases used for product separation are also included as raw materials. Susarla et al assumed a lifetime of 1.5 years for zeolite material used in continuous vacuum swing adsorption. Since thermal regeneration is known to promote adsorbent degradation, one year was assumed for the silicalite under the current operational conditions.…”

The conceptual design of a bio-based process for 2-butanol production is presented for the first time. Considering a hypothetical efficient producing strain, a vacuum fermentation is proposed to alleviate product toxicity, but the main challenge is the energy-efficient product recovery from the vapor. Three downstream scenarios were examined for this purpose: 1) multi-stage vapor recompression; 2) temperature swing adsorption; and 3) vapor absorption. The processes were simulated using Aspen Plus, considering a production capacity of 101 kton/yr. Process optimization was performed targeting the minimum selling price of 2-butanol. The feasibility of the different configurations was analyzed based on the global energy requirements and capital expenditure. The use of integrated adsorption and absorption minimized the energy duty required for azeotrope purification, which represents 11% of the total operational expenditure in Scenario 1. The minimum selling price of 2-butanol as commodity chemical was estimated as 1.05 $/kg, 1.21 $/kg, and 1.03 $/kg regarding the fermentation integrated with downstream scenarios 1), 2), and 3), respectively. Significant savings in 2-butanol production could be achieved in the suggested integrated configurations if more efficient microbial strains were engineered, and more selective adsorption and absorption materials were found for product recovery.

“…In this work, a PSA cycle was designed and simulated by using the best sample of AC derived from the CMSW for purification purposes. The cycle comprises typical four main steps including: i) pressurization with feed, ii) feed at high-pressure, iii) co-current depressurization, and iv) counter-current purge [37,38]. The considered boundary conditions to design the system of partial differential equations are presented in Table 2 .…”

Recently, developing bio-based carbon materials due to the surface chemistry and a large spectrum of pore structures have received much attention. In the present work, a series of activated carbon (AC) adsorbents were synthesized from the compost derived by the mechanical/biological treatment of municipal solid wastes and evaluated regarding their CO 2 uptake. The AC samples were characterized by sulfuric acid and calcination by N 2 at 400 and 800°C. Then, the CO 2 uptake capacities were evaluated by dynamic breakthrough experiments in a temperature range of 40-100°C and pressures up to 3 bar. The presented data were properly described by Langmuir model and it was revealed that the CMSW-S-800 sample, treated with sulfuric acid and activated at 800°C, has the highest CO 2 uptake capacity with an amount adsorbed around 2.6 mol/kg at 40°C. In the next step, a mathematical model has been developed to match the experimental dynamic breakthrough data and design a pressure swing adsorption (PSA) cyclic process to evaluate the capacity and potential of the best AC sample for CO 2 adsorption. The results arising from this work showed a possible route for the application of the compost as a source of activated carbon for the sorption of greenhouse gases.
