“…A geração de recuperação de calor residual (WHRG-Waste heat recovery generation) é um sistema de usina que utiliza o gás de combustão para gerar uma energia elétrica na indústria do cimento (BIYANTO et al,2015) Portanto, cogeração de energia é a geração de energia elétrica produzida através dos gases de combustão gerados por uma fábrica de cimento. Furtado (2016), em uma análise sobre o imenso potencial inexplorado no país, comenta sobre uma iniciativa do reaproveitamento de calor de processos para geração de energia elétrica, com turbinas a vapor; embasado no estudo do Instituto Nacional de Tecnologia que mostrou diversas possibilidades de ganhos na área térmica e elétrica.…”

“…Using this way of working, an operational scenario that allows increasing production and improving the company profitability was identified. According to the above, a proposal was made to conduct the catalytic converter simulation by using the software Aspen HYSYS® Educational license provided by Aspen Technology, Inc., which has been widely used for an in-depth analysis and optimization of various productive processes [12][13][14][15][16][17][18]. This tool allows analyzing performance by means of operational changes and simulating the process using design data provided by the company.…”

The integration of both sensors and simulation in some industrial processes has received a large increase in the recent years, thanks to results such as increase in production indices or improvement in economic indicators. This document describes the development and validation of a simulation-based computer process for generating sulphuric acid. For this process, the data generated by simulation between the fixed beds of a catalytic reactor versus the results obtained using real data from a sulphuric acid production plant in the Antofagasta Region, Chile, have been used. This sulphuric acid production plant is designed for producing 720,000 tons of sulphuric acid annually, with a production capacity of 26 MW, which is used for both its own consumption and the Big North Interconnected System (SING, for its acronym in Spanish) and a sulphur consumption of 240,000 tons/year. For the simulation process, converter input variables such as temperature and gas flow to later observe the oxidation behavior under different operational scenarios were considered. To do it, a working method has been proposed and the software Aspen HYSYS® was used for the simulation. The simulation result was validated using design operational data provided by the company. The real results show a 99.9% of adjustment concerning the values obtained using the simulation. Based on the findings, a new operational scenario was created, and the economic indicators of the simulator implementation were determined: NPV=CLP 161,695,000 and IRR=53% with a 6% monthly production increase.

“…The second contribution is that extensive controllability and interaction analysis is performed for the entire CFB boiler using the DRGA and the PRG, which has not been done before. The steady-state RGA has been used to some extent, − commonly for the 3 × 3 input–output Åström-Bell drum boiler model. , For example, the block relative gain was also used for a 4 × 4 furnace temperature control problem by Manousiouthakis et al Unlike the existing papers, the present work not only addresses the control structure selection in a large 8 × 8 system, but also aims at analyzing the OTU-CFB to provide reasons for reduced controllability. The focus is on current OTU-CFB layouts, but the paper also serves as an evaluation of the chosen methods for future flowsheets, which may differ from current designs (e.g., combined heat and solar power).…”

Combustion power plants currently face major performance challenges, which require robust control design methods. Extensive relative gain analysis was conducted in this paper to generate plantwide control structures for a full-scale once-through circulating fluidized bed boiler. No such study has been reported before for steam boilers. The partial relative gain was employed to generate decentralized control structures based on integral controllability with integrity. The approach provided feasible control structures and verified that basic turbinefollowing boiler control is preferable in terms of controllability. The steady-state results were extended with the dynamic relative gain array for higher frequencies, which revealed that boiler-following control becomes feasible for faster disturbances. The results highlight the complex interactions between steam pressure and output electrical power control, as well as the loop interactions caused by the feedwater flow in the once-through steam path.
