O Biogás e biometano tem um enorme potencial no Brasil, dada a escala de produção de rejeitos industriais, agrícolas e urbanos. Cada vez mais aumenta o interesse pela produção estes combustíveis, e que muitas pessoas não sabem é que já existem cases de sucesso no Brasil relativos a estes biocombustíveis. Neste post, a FIGENER mostra um pouco do que já existe no Brasil e o tanto que o biogás pode representar na energia do país – onde a equipe técnica capacitada e experiência de 30 anos atuando na área de energia da FIGENER são o diferencial para atuar em diversas frentes num projeto de produção e integração de biogás e biometano na área industrial e de distribuição e gás.
Autor: Caio Joppert O biogás e biometano é uma realidade fora do Brasil, principalmente na Europa. Mas o setor energético no Brasil ainda tem receio de investir em empreendimentos de biogás e biometano, e um dos principais motivos é a impressão de que aspectos regulatórios e normativos ainda não estão estabelecidos no Brasil. No entanto,…

The increase in the complexity and size of the projects, as well as the need to guarantee the quality of the work performed, demand an efficient engineering process for the design and construction of substations. The traditional process based on plans and 2D drawings and lists of materials disaggregated among themselves do not allow the necessary agility to the workflow.
In partnership with CNI and ABRACE, FIGENER produced in 2012 a document with the concepts of a measurement and verification methodology (M&V) in order to clearly identify the reduction in energy consumption (electricity and fuels) and the respective reduction of greenhouse gas emissions resulting from industrial energy efficiency projects.
This paper presents the results obtained in the analysis for a typical FPSO electrical power system. The main objective of this analysis is to verify the presence of delayed currents zeros, the non-zero times and how the system operational condition and type of event may influence the results.
This work presents the results obtained in the study whose objective was to investigate the possibilities and alternatives of using natural gas for the forced drying of clay that is used in the production process of ceramic tiles.
This work proposes a new approach to the analysis of electrical stability of industrial cogeneration systems that integrates the characteristics and controls of the steam system to the electrical model.
A statistical approach through an innovative methodology and the optimal allocation of investments.
Parallelism of self-generating industrial systems and the public network: technical aspects of systems integration and future perspectives
This work deals with the technical aspects of parallelism with a focus on the typical philosophies of operation and protection of parallelism adopted today by cogeneration industries, based on studies carried out by FIGENER in the last two years. The work is developed in order to identify the aspects that can be improved and that allow a better integration between self-producers and electric energy concessionaires aiming at the global improvement of the quality of the electric energy supply and the energy efficiency.
This paper discusses the practical aspects of implementing the optimizer for COPENE's thermoelectric generation system, which aims to determine the operational conditions that minimize fuel and electricity costs. The focus will be on the modeling, simulation and database of the system and the interface with the supervisory system.
Despite the fact that digital protection, measurement and control systems are already used on a large scale in electrical power systems, many of the criteria used in electrical systems are still the same as those of electromechanical equipment, not allowing the full use of all the benefits that this type of equipment can bring to the electrical system as a whole.
Several industries of all sizes have converted their flamotubular boilers to oil for operation with natural or dual gas (oil/gas).
Transient analysis of integrated power systems to the dynamic behavior of protection devices: aspects of relay modeling
This article describes a generic approach to model the static and dynamic behavior of protection relays. A protection relay - overcurrent, impedance or any other type - is modeled using a multi-level method.
