“…[22] Therefore, a continuously producing multipurpose plant that can adapt its capacity to the market developments [23] and produce different products can be of strategic advantage. [24] Another strategy could be to enable a fast time to market by utilizing and modifying an already designed plant. [25] On the other hand, world-scale plants in bulk and basic chemicals are dominant.…”

Increasing economic and environmental challenges leads to the need for changes in the chemical industry. In this context, a promising approach is utilizing flexible apparatuses and flexible plants to react to changing boundary conditions. However, the concept of flexibility in chemical engineering, which originated in manufacturing, still lacks a comprehensive organization and categorization of different types of flexibility. Thus, in this work, the origin of flexibility in manufacturing is traced, and a literature overview on flexibility in chemical engineering is provided. Based on a subsequent cluster analysis, four types of flexibility are identified and defined. Furthermore, this work enables research on flexibility to be integrated into a general and consistent definition of flexibility. The definitions are applied to examples from literature to achieve comparability. While enabling the qualitative assessment of flexibility, this work identifies open research gaps regarding the quantification of flexibility.

“…Balanços de massa e energia da usina kraft de celulose considerada nesse estudo representam uma fábrica moderna no Brasil que produz 1,25 milhões de toneladas de polpa celulósica por ano (adt/ano) e tem excedente de energia elétrica de 19 MW (Figura 1; detalhes da usina estão disponíveis em Pereira et al, 2018). Para o projeto da planta de açúcares lignocelulósicos a ser anexada a usina de celulose foram avaliadas duas tecnologias de prétratamento (Organosolv e explosão a vapor) e três tipos de biomassaeucalipto convencional, 52 US$/ton seca; floresta energética de eucalipto, 56 US$/ton seca; e canaenergia, 39 US$/ton seca.…”

Produtores de celulose estão interessados em expandir seus negócios para a bioeconomia e uma opção são os açúcares lignocelulósicos. Contudo, ainda é desconhecido se biorrefinarias anexas a plantas kraft de celulose podem oferecer açúcares lignocelulósicos a preço competitivo. Por isso, desenvolvemos projetos conceituais de biorrefinarias considerando três tipos de biomassa (eucalipto convencional, floresta energética de eucalipto e cana-energia) e dois tipos de prétratamento (explosão a vapor e Organosolv). A opção que combina cana-energia e explosão a vapor ofereceu o preço mais competitivo de açúcares (186 USD/t contra 220-338 USD/t das outras opções). A cana-energia dessa maneira pode ser um fator de integração da indústria da celulose de eucalipto com o setor sucroenergético da cana.
