One-layer gradient-based MPC + RTO of a propylene/propane splitter
(Pergamon-Elsevier Science Ltd, 2017-11)
Here, the implementation of the gradient-based Economic MPC (Model Predictive Control) in an industrial distillation system is studied. The approach is an alternative to overcome the conflict between the MPC and RTO (Real ...
Modelagem cinética da produção de propeno a partir de acetona em uma única etapa
(Universidade Federal de Santa MariaBREngenharia de ProcessosUFSMPrograma de Pós-Graduação em Engenharia de Processos, 2014-02-19)
Propylene is a chemical compound with high value added, widely used in the industry and
usually obtained from petroleum. However, there is the need of the development of alternative
routes for the production of this ...
Hybrid model generation for superstructure optimization with Generalized Disjunctive Programming
(Pergamon-Elsevier Science Ltd, 2021-11)
We propose a novel iterative procedure to generate hybrid models (HMs) within an optimization framework to solve design problems. HMs are based on first principle and surrogate models (SMs) and they may represent potential ...
Optimal design of ethylene and propylene coproduction plants with generalized disjunctive programming and state equipment network models
(Pergamon-Elsevier Science Ltd, 2021-06)
In this work, we propose a superstructure optimization approach for the optimal design of an ethylene and propylene coproduction plant. We formulate a superstructure that embeds ethane and propane steam cracking technologies, ...
Avaliação dos parâmetros operacionais de uma torre de destilação de propeno
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia QuímicaUTFPR, 2018-06-12)
Propylene in a degree of purity above 99,5% in molar fraction (polymer grade) is a first generation basic petrochemical and It is also a vital link of refining-petrochemical integration in Brazil. This, associated with the ...
Estudo de viabilidade técnico-econômica para a implementação de unidades produtoras de propeno e polipropileno, a partir do gás liqüefeito de petróleo produzido na refinaria Gabriel Passos (Betim-MG), utilizando a técnica de opções reais
(Universidade Federal de Minas GeraisUFMG, 2005-06-24)
The technical and economical feasibility study were developed for the implementation of an industrial polypropylene complex in the Minas Gerais, State, Brazil, applying the Real Options analysis. The petrochemical complex ...
Valorization of Polyolefins Dissolved in Light Cycle Oil over HY Zeolites under Fluid Catalytic Cracking Unit Conditions
(American Chemical Society, 2003-07)
A study has been made of the valorization of polyolefins, PE (polyethylene) and PP (polypropylene), dissolved in LCO [light cycle oil obtained as a product stream in a fluid catalytic cracking (FCC) unit] by their cracking ...
Impact of traces of hydrogen sulfide on the efficiency of ziegler–natta catalyst on the final properties of polypropylene
(John Wiley & Sons Inc.United States, 2022)
Síntesis de procesos para la adición de valor y la diversificación de los productos derivados del ácido láctico mediante la metodología P-graph.
(Universidad Nacional de Colombia - Sede Bogotá, 2020-01-30)
This work illustrates the implementation of P-graph methodology for process synthesis, to generate conceptual designs, aiming at the addition of value for the products of the sugar cane’s productive chain. Specifically, ...
