Co2 Capture Systems

In this report, novel systems, based on highly abundant saccharides, d-mannose, d-glucose, β-cyclodextrin, alginic acid and mannitol, in combination with an organic superbase, tetramethylguanidine (TMG) or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), are studied for carbon dioxide capture. With d-mannose and d-glucose, several ratios of equivalents of alcohol groups of saccharide : superbase were tested: 1, 0.625, 0.5 and 0.25. High wt% values of CO2 uptake were obtained with TMG-based systems. However, TMG itself can react directly with CO2, and, in the presence of d-mannose, competition between carbonate and carbamate based products was established. In order to circumvent this competition and obtain exclusively the carbonate-based product, DBU was used instead as an organic superbase. In the d-mannose series the highest result was obtained with a d-mannose : DBU ratio eq. = 0.625 (13.9% CO2 uptake, 3.3/5 alcohol groups converted into carbonates). A more effective stirring system, designed to overcome the high viscosity of the products, allowed the use of a d-glucose : DBU = 1 : 1 ratio with 11.5 wt% of CO2 uptake and 2.47/5 alcohol groups converted into carbonates. Additionally a DSC thermal study was performed in order to study the stability/reversibility of the CO2 loaded systems.

Abstract Greenhouse gases emissions from large scale industries as well as gasoline based vehicles are mainly responsible for global warming since the 1980s. At present, it has triggered global efforts to reduce the level of GHG. The contribution of carbon dioxide (CO2) in polluting the environment is at a peak due to the excessive use of coal in power plants. So, serious attention is required to reduce the level of CO2 using advanced technologies. Carbon dioxide capture and storage may play an important role in this direction. In process industries, various carbon dioxide capture techniques can be used to reduce CO2 emissions. However, post-combustion carbon dioxide capture is on top priority. Nowadays the researcher is focusing their work on CO2 capture using hybrid solvent. This work highlights a review of carbon dioxide capture using various kind of hybrid solvent in a packed column. The various challenges for absorption efficiency enhancement and future direction are also discussed in the present work. It is concluded through the literature survey that hybrid solvent shows better efficiency in comparison to the aqueous solution used for CO2 capture.

Gasification Technology

Integrated Gasification Combined Cycle (IGCC) is believed to be one of the most promising technologies to offer electricity and other de-carbon fuels with carbon capture requirement as well as to meet other emission regulations at a relatively low cost. As one of the most important parts, different gasification technologies can greatly influence the performance of the system. This paper develops a model to examine the feasibilities and advantages of using Ultra Superheated Steam (USS) gasification technology in IGCC power plant with carbon dioxide capture and storage (CCS). USS gasification technology converts coal into syngas by the endothermic steam reforming reaction, and the heat required for this reaction is provided by the sensible heat in the ultra superheated steam. A burner utilizes synthetic air (21% O2 and 79% H2O) to burn fuel gas to produce the USS flame for the gasification process. The syngas generated from USS gasification has a higher hydrogen fraction (more than 50%) then other gasification processes. This high ratio of hydrogen is considered to be desired for a “capture-ready” IGCC plant. After gas cleanup and water gas shift reaction, the syngas goes to the Selexol process for carbon dioxide removal. Detailed calculations and analysis are performed to test the performance of USS gasification technology used in IGCC generation systems. Final results such as net output, efficiency penalty for CO2 capture part, and net thermal efficiency are calculated and compared when three different coal types are used. This paper uses published data of USS gasification from previous research at the University of North Dakota. The model also tries to treat the IGCC with carbon dioxide capture system as a whole thermal system, the superheated steam used in USS gasification can be provided by extracting steam from the lower pressure turbine in the Rankine Cycle. The model will make reasonable use of various waste energies and steams for both mechanical and chemical processes to improve the performance of the plant, and incorporate CO2 capture system into the design concept of the power plant.

Spontaneous atmospheric CO2 capture as carbonate anion occurred in the synthesis of a trinuclear Cd(II) complex with tris(2-aminoethyl)amine ligand. In reaction two types of compounds were obtained and structurally characterized by X-ray diffraction on a single crystal: initially [{Cd(tren)}3(tren)](ClO4)6·2H2O (1) and subsequently [{Cd(tren)}3(tren)][{Cd(tren)}3(µ3-ηCO3)](ClO4)10 (2). The carbonate anion replaces partially the bridging tren molecule and coordinates in a µ3 fashion. The luminescent properties of the compounds were investigated.

Cobalt dopping Fe-MIL-88B were successfully synthesized -in solvothermal procedure using DMF as solvent and with/without NaOH. The samples were characterized using SEM, BET and TGA techniques. The partly substitution of Fe by Co does not change the octahedral shape of their parent Fe-MIL-88B. Crystallizations conducted in NaOH medium, however, results in rod like with 2-end octahedral shape crystals. The BET specific surface area is 139cm2/g. The TGA data indicated that the presence of Co resulted in an increase in thermal stability of synthesized samples compared to parent Fe-MIL-88B. The CO2 adsorption isotherms in Fe-MIL-88B-Co samples were measured volumetrically at five temperatures:278K, 288K, 298K, 308K, 318K. The obtained results showed that Fe-MIL-88B-Co is a potential adsorbent with a maximum adsortption capacity of 1.2312 mmol/g (at T= 278K). The sample synthesized in alkali medium exhibited a better adsorbent for CO2 storage. Keywords MIL, adsorption, CO2 References [1] S.

Co2 Capture Systems

Global focus on greenhouse gas emissions has led the United State’s legislature to discuss various strategies to reduce carbon dioxide (CO2) emissions. With coal-fired plants responsible for roughly half of United States (U.S.) electricity generation and approximately 30% of the nation’s CO2 emissions, coal-fired plants will be largely affected by any future CO2 emission regulations. However, coal-based generation could continue to meet our electricity demands while complying with future CO2 emissions restrictions with the addition of carbon dioxide capture and sequestration (CCS) technology. Most studies of CCS systems have demonstrated a permanent energy requirement of 11–40% of a plant’s output when operating continuously at a 90% CO2 removal rate. This study, however, used a dynamic model of the Electric Reliability Council of Texas (ERCOT) electric grid to consider post-combustion CO2 capture systems that can operate flexibly. Post-combustion CO2 capture systems using chemical absorption and stripping are particularly suited for retrofitting existing plants and operating in a flexible manner. Flexible carbon capture allows plant operators to vary the energy used for CO2 capture and compression in order to regain this generation capacity when desirable. Thus, flexibility can be used to choose the CO2 capture rate that allows the most economical combination of operating costs, electricity price, and output levels. Furthermore, operating at lower CO2 capture energy requirement levels and increasing output capacity during peak demand periods could dramatically reduce the amount of replacement capacity needed to replace potential output lost when CO2 capture systems are in operation. This research uses an existing modeling framework of a dynamic hourly dispatch system to study the economic, environmental, and performance implications of flexible CO2 capture over an investment lifetime. The effects of CO2 prices, natural gas fuel prices, and replacement capacity costs were analyzed along with various operating strategies. The fuel mixture behavior and emissions effects are presented, showing that large emissions reductions can be achieved using the current ERCOT plant fleet with the addition of flexible CO2 capture. An annual system-level cash-flow analysis is used to determine a net present value (NPV) for a group of CO2 capture plants under a range of possible replacement capacity costs. If replacement capacity costs are accounted for, flexibility can improve the NPV of a CO2 capture investment by substantially lowering the associated capital costs to replace output lost to CO2 capture energy requirements.

Integrated Gasification Combined Cycle (IGCC) is believed to be one of the most promising technologies to offer electricity and other de-carbon fuels with carbon capture requirement at a relatively low cost. With the process of carbon dioxide capture, it can also actually meet strict regulations for other pollutants emission. However, the performances can vary depending on what kinds of technologies or processes are used. This paper has developed a model and calculated by using Engineering Equation Solver (EES) program to determine and compare different available technologies and processes. There are four main components in the model: Gasification Island; Gas Cleanup Island; Carbon Dioxide Capture Island and Power Island. Among them, the different options of Gasification Island; and Carbon Dioxide Capture Island are expected to be the most effective factors to influence the performance of the plant. Therefore, different gasification processes are examined in this paper, including Shell, GE (Texaco) and Lurgi. The carbon dioxide capture processes are based on SELEXOL, a physical absorption process, because of the high partial pressure of carbon dioxide in the syngas. A process called “double-absorption” is used for capturing sulfur compounds and carbon dioxide. This paper calculated and compared the net outputs, efficiency penalties for CO2 capture part, and net plant efficiencies for different technologies and processes by using EES program. This model tries to treat the IGCC with carbon dioxide capture part as a whole thermal system, instead of just looking at the capture system alone. Different gasification technologies mentioned above will result in various paths and efficiencies of using steam and waste energy in the system. It will make reasonable use of various waste energies and steams for both mechanical and chemical processes to improve the performance of the plant, and incorporate a CO2 capture system into the design concept of the power plant.
