This book was released on 2016 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intensive energy use is the major obstacle to deployment of CO2 capture. Alternative stripper configurations is one of the most promising ways to reduce the energy consumption of CO2 regeneration and compression. The advanced flash stripper (AFS) proposed in this work provides the best energy performance among other alternatives. A systematic irreversibility analysis was performed instead of examining all the possible alternatives. The overhead condenser and the cross exchanger were identified the major sources of lost work that causes process inefficiencies. The AFS reduces the reboiler duty by 16% and the total equivalent work by 11% compared to the simple stripper using aqueous piperazine. The AFS was demonstrated in a 0.2 MW equivalent pilot plant and showed over 25% of heat duty reduction compared to previous campaigns, achieving 2.1 GJ/tonne CO2 of heat duty and 32 kJ/mol CO2 of total equivalent work. The proposed bypass control strategy was successfully demonstrated and minimized the reboiler duty. Approximate stripper models (ASM) were developed to generalize the effect of solvent properties on energy performance and guide solvent selections. High heat of absorption can increase partial pressure of CO2 at elevated temperature and has potential to reduce compression work and stripping steam heat. The optimum heat of absorption was quantified as 70–125 kJ/mol CO2 at various conditions, which is generally higher than existing amines with 60–80 kJ/mol. The energy performance of AFS is not sensitive to the heat of absorption. A techno-economic analysis with process optimization that minimizes the annualized regeneration cost was performed to demonstrate the profitability of the AFS. The AFS reduces the annualized regeneration cost by 13% and the major savings come from the reduction of the OPEX, which counts for over 70% of the regeneration cost. The compressor and the cross exchanger are the major components of the CAPEX. The optimum lean loading is around 0.22 mol CO2/mol alkalinity for PZ but is flat between 0.18 and 0.24 with less than 1% difference. The AFS was demonstrated as a flexible system that can be applied to a wide range of solvent properties and operating conditions while still maintaining remarkable energy performance. Further improvement of energy efficiency by process modifications is expected to be marginal. Increasing solvent capacity will give the most energy and cost reduction in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Implementation of carbon capture using amine scrubbing is limited by the large energy penalty of CO2 capture and compression. Alternative stripper designs can reduce lost work in the stripper by implementing heat recovery unit operations and reducing opportunities for solvent degradation. The advanced flash stripper (AFS) has reduced the required equivalent work by 12-15% compared to the simple stripper by using multiple solvent bypasses to equalize heat capacity across cross exchangers and minimizing lost latent heat of water vapor in the condenser. The Advanced Flash Stripper using 5 m piperazine was studied at the National Carbon Capture Center (NCCC) pilot plant, which presented the novel opportunity to test the solvent and design configuration with coal-fired power plant flue gas. Piperazine (PZ) solvent was stripped of CO2 with an average stripper operating temperature of 150 °C The energy cost averaged 2.2 GJ/MT CO2 for the AFS and 3.8 GJ/MT CO2 for the simple stripper (SS). A temperature-control heuristic for controlling bypass flowrates was evaluated using five AFS test cases. Using bypass temperature differences of 7 °C, the bypass rates were automatically controlled to within 5% of the optimal bypass configuration. While the method was successful in simulations, unexpected heat loss in the NCCC plant limited the accuracy of the temperature-control heuristic due to the heat loss reducing the benefits of heat recovery unit operations. Overall energy balances of the AFS using the Independence model showed a positive heat gain of 65000 Btu/hr. The unexpected heat gain was attributed to an overestimated heat of absorption in the Independence model, as well as an underestimation of the total heat transferred from the process steam. A test AFS run was analyzed using three different assumption methods, with energy requirements varying from 2.1 – 3.0 GJ/MT CO2.

Download or read book Modeling the Advanced Flash Stripper for CO2 Capture Using 5 M Piperazine written by Junyuan Ding and published by . This book was released on 2016 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amine scrubbing is the most mature technology for post-combustion CO2 capture. Several studies have demonstrated that the advanced flash stripper (AFS) consumes less energy among stripper alternatives. This thesis seeks to demonstrate the AFS energy performance and cost over a wide range of CO2 loading. Solvent models based on experimental results have been created by previous researchers and are available for simulation and process modeling in Aspen Plus®. In collaboration with Membrane Technology and Research Inc., various hybrid amine/membrane configurations were studied to minimize the total CO2 capture cost. CO2 in the flue gas is enriched by membranes from 12% to 18 and 23% for coal-fired power plant, and from 6% to 12~18% for natural gas combined cycle power plant (NGCC). The CO2 loading covers the range of flue gas CO2 from coal-fired power plants and NGCC. For each configuration, the cold and warm rich bypasses are optimized to minimize the energy cost. The cost optimization is also demonstrated on 5 m PZ, 5 m MDEA/5 m PZ, and 2 m PZ/3 m HMPD. The most cost-effective solvent varies with the flue gas CO2. When applied to a coal-fired power plant, hybrid parallel amine/membrane designs with 99% and 95% CO2 removal cost less than hybrid series with 60% CO2 removal. The equivalent work of the parallel configuration with 99% CO2 removal using 5 m MDEA/5 m PZ (32.3 kJ/mol CO2) is less than using 5 m PZ (34.0 kJ/mol CO2). The equivalent work with 95% CO2 removal (Case 19) using 5 m MDEA/5 m PZ (32.5 kJ/mol CO2) is less than using 5 m PZ (33.3 kJ/mol CO2). The capital cost with 99% CO2 removal using 5 m MDEA/5 m PZ ($70.5MM) is more than using 5 m PZ ($67.5MM). The capital cost with 95% CO2 removal using 5 m MDEA/5 m PZ ($73.5MM) is less than using 5 m PZ ($79.5MM). The total annual cost with 95% CO2 removal using 2 m PZ/3 m HMPD ($38.7/tonne CO2) is less than using 5 m PZ ($41.5/tonne CO2). When applied to NGCC, the cost of amine scrubbing is reduced by increasing absorber inlet CO2 by membranes. However, this is offset by the membrane cost. As absorber inlet CO2 increases from 6% to 18%, the operating cost decreases from $18.8 to $15.4/tonne CO2, while total regeneration cost decreases from $35.6 to $33.1/tonne CO2.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis seeks to improve the economic viability of carbon capture process by reducing the energy requirement of amine scrubbing technology. High steam requirement for solvent regeneration in this technology can be reduced by improvements in the regeneration process. Solvent models based on experimental results have been created by previous researchers and are available for simulation and process modeling in Aspen Plus®. Standard process modeling specifications are developed and multiple regeneration processes are compared for piperazine (a cyclic diamine) in Chapter 2. The configurations were optimized to identify optimal operating conditions for energy performance. These processes utilize methods of better heat recovery and effective separation and show 2 to 8% improvement in energy requirement as compared to conventional absorber-stripper configuration. The best configuration is the interheated stripper which requires equivalent work of 29.9 kJ/mol CO2 compared to 32.6 kJ/mol CO2 for the simple stripper. The Fawkes and Independence solvent models were used for modeling and simulation. A new regeneration configuration called the advanced flash stripper (patent pending) was developed and simulated using the Independence model. Multiple complex levels of the process were simulated and results show more than 10% improvement in energy performance. Multiple cases of operating conditions and process specifications were simulated and the best case requires equivalent work of 29 kJ/mol CO2. This work also includes modeling and simulation of pilot plant campaigns carried out for demonstration of a piperazine with a 2-stage flash on at 1 tpd CO2. Reconciliation of data was done in Aspen Plus for solvent model validation. The solvent model predicted results consistent with the measured values. A systematic error of approximately +5% was found in the rich CO2, that can be attributed to laboratory measurement errors, instrument measurement errors, and standard deviation in solvent model data. Stripper Modeling for CO2 capture from natural gas combustion was done under a project by TOTAL through the Process Science and Technology Center. Two configurations were simulated for each of three flue gas conditions (corresponding to 3%, 6% and 9% CO2). Best cases for the three conditions of flue gas require 34.9, 33.1 and 31.6 kJ/mol CO2.
