The existing studies largely focused on extracting specific knowledge from human experience or directly optimizing the scheduling performance, which failed to provide a dynamic optimization process for making the scheduling scheme updated online. In this study, an action-dependent heuristic dynamic programming (ADHDP) framework is proposed for the Linz-Donawitz converter gas (LDG) scheduling, in which the scheduling amount is calculated based on the gas system states by utilizing a Tagaki-Sugeno-Kang (TSK) fuzzy model, while a utility function is introduced in the critic network considering the time delay of the gas system to evaluate the scheduling performance over time. For achieving online learning process, the concept of a modified evolutionary algorithm is combined with the ADHDP to obtain the near-optimal scheduling policy at each time instance. To demonstrate the performance of the proposed method, the practical data coming from the energy center of a steel plant are employed. The results show that the proposed method can supply the human operators with effective solution for secure and economically justified optimization of the LDG system.","PeriodicalId":170851,"journal":{"name":"2017 6th International Symposium on Advanced Control of Industrial Processes (AdCONIP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130042179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key objective of this work is to control and optimize the purity and recovery of the adsorption product (carbon dioxide) by manipulating the time duration of the VPSA cycle steps. Based on a single fixed-bed 6-step VPSA process simulation using 5A zeolite as adsorbent for CO2 capture from gas mixture with 15% CO2 and 85% N2 (resembling post-combustion flue gases of power stations), a two-input/two-output control model was obtained, in which Feed step time and Purge step time are taken as manipulative variables and CO2 Purity and Recovery are the controlled variables. For control purpose, a multi-input/multi-output model predictive control (MIMO-MPC) system is proposed to handle the inherent non-linear nature and discontinuous operation of the VPSA process. The MIMO-MPC control scheme is tested and showed good results in terms of system stability and fast tracking of the set-points. Finally, PSO algorithm is applied to maximize the purity and recovery by finding the optimal duration time of feed step and purge step, the results shows that with such VPSA process, over 98% of CO2 is recovered with purity of 59%, at tfeed = 202s and tpurge= 114s.","PeriodicalId":170851,"journal":{"name":"2017 6th International Symposium on Advanced Control of Industrial Processes (AdCONIP)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122555833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional ECH production methods suffer from several disadvantages. Hydrogen peroxide is relatively non-toxic and widely accepted as an environmentally friendly and green oxidant. In the study, we propose the plant-wide process design and control for ECH synthesis by the epoxidation of allyl chloride with hydrogen peroxides over the catalyst of TS-1 in the presence of methanol. In the plant-wide process, the product from a plug flow reactor is separated by a distillation column. Nitrogen gas is fed into the column top for safety concerns. The column bottom product containing mostly ECH and water is decanted into two liquid phases. High purity ECH and water are obtained from the bottoms of two strippers which the liquids of organic and aqueous phases in the decanter are respectively fed into. The control strategy is constructed by steady-state analysis for the plant-wide process and its performance is evaluated by dynamic simulation. Simulation results reveal that the process can be safely operated and product purities can be maintained around the desired values by temperature control in spite of disturbances.","PeriodicalId":170851,"journal":{"name":"2017 6th International Symposium on Advanced Control of Industrial Processes (AdCONIP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124538450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photosynthetic fixation of atmospheric carbon into biomass, followed by carbonization of plant biomass into stable biochar which is then added to soil, results in a reversal of the normal flow of carbon from man-made systems. In addition, these systems can provide economic benefits, such as enhancement of soil quality for agriculture, or co-production of valuable goods (e.g., energy and chemicals) along with biochar. However, the amount of biochar that can be added to agricultural land without causing adverse effects is limited by impurities such as salts, heavy metals and dioxins, which can cause a decline in soil quality. Thus, allocation of biochar from different sources (i.e., pyrolysis plants) to different sinks (i.e., farms or plantations) can be framed as a source-sink optimizations problem. In process integration literature, such problems have been solved via mathematical programming, pinch analysis or allied techniques such as process graphs. In this work, a pinch analysis approach for planning biochar-based carbon management networks is proposed. This methodology provides an alternative or complementary approach that facilitates decision-making and interpretation through visually oriented graphical displays. A case study is solved to illustrate how system-wide carbon sequestration can be maximized, while still satisfying soil impurity limits.","PeriodicalId":170851,"journal":{"name":"2017 6th International Symposium on Advanced Control of Industrial Processes (AdCONIP)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115064999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new double-layered model predictive control strategy with dynamic trajectory calculation (DTC) in its upper layer is presented in this paper, which can be applied in the midst of a hierarchical control system. DTC includes a feasibility stage with prioritized constraints handling and an economic optimization stage in a compatible constraint set. The calculated trajectory for each output is tracked by MPC dynamically in the lower layer. The presented control algorithm with DTC inspired by the steady-state target calculation (SSTC) method from the existing research basis. It could achieve a better economic benefit and tracking effect of external targets (ET) obtained from real-time optimization (RTO). In the simulation example, the introduced and original algorithms are applied to a fluid catalytic cracking (FCC) model which is the core of refining industry.
